Air Purification

Clean Rooms in Pharmaceutical Production

Pharmaceutical production is a critical industry for supporting the healthcare and well-being of the world’s population – is it also a tightly regulated industry with precise methods developed through decades of scientific study. Stringent conditions that must be the same in all circumstances are placed on pharmaceutical production to guarantee that the outputs will be virtually identical in all cases. When administering a sensitive or concentrated pharmaceutical product, even very slight impurities or contaminants could lead to widely varied and undesirable outcomes meaning healthcare practitioners need absolute confidence in what they are prescribing. It is for this reason that clean rooms place a vital role in pharmaceutical production, and in turn medical-grade air purification systems that create clean room conditions like the Air Fit from Aeroex.

How Does Air Purification Help Pharmaceutical Production?

Clean rooms with air purification address many of the quality and safety priorities of the pharmaceutical industry. Common conceptions of how we transmit contaminants could include things like breathing germs, not washing your hands, not having a clean workstation, etc. However, there are actually many airborne contaminants like dust, pollen, aerosols, and bacteria in ambient atmospheric conditions that would interfere with pharmaceutical production if they were not removed. Many of these contaminants are not detectable to the naked eye, meaning incredibly fine filtration or other methods of purification are needed to remove them. This helps the pharmaceutical industry by providing a guarantee that impurities will not enter a product at any stage in the pharmaceutical production process. 

Clean rooms can also support other industries as recognized by the recent updates in clean room ISO standards, which cited food production, aerospace, and automotive manufacturing as other applications.

What is a Clean Room for Pharmaceutical Production?

Clean rooms are used in a variety of industries but are most common in pharmaceutical production on account of the previously mentioned quality requirements. According to ISO 14544:2015, clean rooms are specified by “the classification of air cleanliness in terms of concentration of airborne particles”… “based on threshold (lower limit) particle sizes ranging from 0.1 µm to 5 µm”. Clean rooms can provide varying levels of stringency and cleanliness – these standards rang from ISO-1 (the “cleanest”) to ISO-9 (the “dirtiest”). 

The most common clean room standards used for pharmaceutical production are ISO-8 and ISO-7. Typically these facilities require a sterile environment but don’t handle hazardous materials. The required air circulation would be around 30 cycles per hour, with approximately 83,000 particles less than one micron in size being allowed per cubic meter of air (this may sound like a lot but not when these particles are incredibly small!). 

Higher standards like ISO-5 are typically reserved for specialized technologies like nanotechnologies where even the smallest impurities can have an outsized impact on very small products. These clean rooms typically require unidirectional flow as well, which not all pharmaceutical clean rooms require provided the right purification takes place. To learn more about clean rooms and the breakdown of air purification requirements and methods, check out our recent article on the subject.

Air Purification for Clean Rooms in Pharmaceutical Production

Aeroex specializes in all types of air purification for industries ranging from swiss lathe machining to public schools or hospitals to specialized manufacturing and pharmaceutical production. Our offering for pharmaceutical production clean rooms is the Air-Fit, a clean room system using ceiling-mounted fan filters equipped with the highest standards in air purification technology. The high-efficiency particulate air filter (HEPA) has an efficiency rating of 99.99% for particles as small as 0.3 μm. This rating is notably smaller than the 0.5μm and 1.0μm requirements of ISO-7 clean rooms cited for industries like pharmaceutical production, making the Air-Fit the ideal model for such clean rooms. 

Calculate the Air Circulation of a Clean Room for Pharmaceutical Production

Clean rooms are defined not just by the level of cleanliness an air purification system can provide, but at what scale and capacity so as to constantly maintain the cleanliness of facility of a given size/volume. Therefore, the air handling of the air purification system needs to be considered. The Air-Fit comes in two models providing either 500 or 1000 cubic feet per minute of air handling, with speed variations within each. To determine your capacity required to circulate purified air at the necessary frequency (for example 30 times per hour), the volume of the clean room needs to be taken into account. The Air-Fit delivers the high air handling using a centrifugal fan and high volumes of filter media. 

In cases where a staged approach to fan filtration was needed, the modular nature of the Air-Fit units and integration with existing mechanical systems could provide the necessary air handling. Typically units should be spaced to provide ambient conditions unless unidirectional flow creates added requirements. If multiple units are deployed, the Air Fit would provide additional benefits (as discussed below) by using a control panel to configure all units simultaneously. 

Ways to Improve your Clean Room

Beyond meeting or exceeding the specifications of clean rooms, the Air Fit provides many other benefits to the operation that can improve your clean room. First, our models provide similar air handling to competitor units but do so more efficiently, using a compact model with a smaller footprint to do so when clean room ceiling “real estate” can be in short supply due to lighting, appliances, containment devices, etc. also appearing on the ceiling. Our control panel for configuring multiple Air-Fit units is easy to use, saving an airflow engineering from having to locate and calibrate each unit individually (they’ll thank you for it with a lower invoice!). Our models are designed and manufactured in Canada, giving a long-lasting unit that adds efficiency with long useful life. Our filters use high filter media and rarely clog, leaving you operating longer without a filter replacement. And when you do need to replace the filter you can easily do it yourself thanks to the improved safety we’ve added to the access hatch after seeing issues in competitor models with this process. These benefits combine to improve your clean room and give you greater value.

Commercial Clean Rooms

Clean rooms are commonly associated with industries like pharmaceuticals and healthcare, but advances in manufacturing have led to clean rooms being used in many other commercial applications. A clean room is a sanitized space that is maintained using air purification along with other measures like gowning, frequent cleaning, and airlocks to create a neutral environment devoid of contaminants that can pose quality issues. Clean rooms are specially designed so that users are able to monitor and maintain the environment of the room by controlling factors such as humidity, temperature, airflow, pressure, and filtration. Aeroex is an experienced supplier of clean room fan filter units like our Air-Fit for the commercial sector – click here to learn more.

Why Do Commercial Industries Need Clean Rooms?

Clean rooms are a necessary part of many commercial applications that require heightened quality or safety standards or use complex processes that could be impinged by airborne contaminants. The primary purpose of a clean room across these industrial applications is to provide a clean working space in which manufacturing processes can take place without interference from contaminants that can jeopardize the final product.

Contaminants include (and are not limited to) dust, vapor, microbes, fibers, as well as other potential biological contaminants. When these particles interfere with a process, products may be wasted or the time and money of the operation could be lost.

Air Purification for Commercial Clean Rooms

An essential piece of equipment employed in clean rooms are air filters, as they are responsible for the control of contaminants within the clean room. Air filters are engineered to trap contaminants as well as to circulate fresh, clean air into the clean room at specified intervals. The type of air filter used will largely depend on the specifications of the clean room in question, as well as the standards set by the ISO 14644. The Air-Fit 500 uses a HEPA filter with 99.97% removal efficiency for 0.3um particles, which is better than many clean room requirements.

From manufacturing to medical and pharmaceutical applications, clean rooms are employed to meet the regulatory standards set by set employment or environmental standards. ISO 14644 typifies clean rooms into 9 separate categories – all of which are defined by the nature and the purpose of the processes used to manufacture the end-product needed. ISO-1 cleanrooms have the strictest standards for cleanliness, and have the least number of particulate in the air. ISO-9 cleanrooms, in comparison, have the lowest standards of the 9 cleanroom classifications. 

Common Commercial Clean Room Applications

In today’s blog we’ll look at a few industries that rely on the use of clean rooms for their manufacturing processes.

Pharmaceutical Production

As mentioned at the introduction, pharmaceutical production facilities are some of the most common applications for clean rooms due to stringent health and safety requirements. These industries are tightly regulated. Clean rooms are also required during medical trials and other scientific investigations where the interference of airborne contaminants needs to be eliminated as a potential unknown variable in the results of any studies.

Medical Device Manufacturing

Whether producing single-use medical devices like syringes and catheters, or implantable devices like pacemakers, any product that’s interacting with bodily systems needs to be full sterile and devoid of any contaminants. History shows the damage and lawsuits that improperly manufactured medical devices can lead to. Therefore, given the intimacy of certain medical devices they are often manufactured in clean room conditions with air purification. 


The aerospace industry requires precision and specification – when thousands of feet up in the air, even the slightest quality issue could lead to an unforeseen challenge. The aerospace industry often enlists other technologies like optical devices and instrumentation that have similar clean room requirements to other aerospace components. Aeroex is a trusted partner for “mission-critical” industries like the aerospace sector. For example, we are trusted by manufacturers supplying nuclear industry clients like CANDU nuclear power utilities.


Optical device manufacturers require clean rooms to ensure no impurities interfere with the crafting of lens and other fine components. These components must be absolutely dust free, and some specialized devices also require specific levels of temperature and humidity. For an illustrative example, check out this interesting showcase of Fujifilm’s use of clean room. Aeroex also has a strong understanding of supporting optical requirements from supplying clients like Benmur Precision with oil mist collectors used in machining parts for Nikon


There is growing awareness of the need to establish clean rooms for the production of solar panels. Typically, solar panel materials have been able to tolerate some impurities that would otherwise be rejected in higher-grade electronics and improvements to the supply chain have mitigated some of the historical quality issues. However with the need to scale up solar and a push for more efficiency, low-level clean rooms are now being used by industry leaders. A recent industry survey found that combustible dust, or gasses from processing, could be creating impurities mitigated by clean rooms.

Food and Beverage Packaging

Clean rooms in the food manufacturing industries often focus on preventing microorganisms from entering the product. This can significantly extend the shelf life of a product by ensuring no contaminants are present that would speed up the deterioration of the product. Clean rooms with air filtration are often paired with other measures to preserve food like chilling. 

The Use of Commercial Clean Rooms is Expanding

With advances in technology, the use cases for clean rooms are continuing to expand. Aeroex is known for being at the forefront of industry developments and we take pride in innovation. Whether you are developing clean rooms for an established industry or you want an air purification partner who can help in developing a new application, Aeroex is your trusted partner for commercial clean room air purification.

What Is A Fan Filter Unit?

Fan filter units are a dual-purpose technology that simultaneously purifies the air in a room with state-of-the-art filtration and increases the airflow through the space in which it’s installed using a motorized fan. Fan filters bring many benefits for workplace health and safety, bring stringent quality to operations with a building, and offer significant value when compared to other technologies that deliver similar functions. Fan filters are commonly used in workplaces and facilities that require purified air and frequent cycling of rooms, such as clean rooms, specialty manufacturing, food, pharmaceuticals, and science labs.

What Does A Fan Filter Do?

Fan filter units purify and circulate air to improve workplace conditions, even creating clean rooms. First, one or more fan filter units are ceiling mounted and integrated with your existing mechanical and electrical systems (models like Aeroex’s Air Fit are lightweight and have a small footprint that makes this part easy). Once installed, the fan filter unit operates a motorized fan that circulates air through the filtration system to purify it by removing 99.99% of all contaminants.

To create clean room conditions, the smallest of airborne contaminants must be removed (smaller than one micron) from the air and circulated with positive pressure. Airborne contaminants could include dust, spores, smoke, vapors, viruses, bacteria, etc. To purify the air, the Aeroex Air Fit fan filter unit first screens out larger particles with a primary filter so they don’t get caught in the more intricate secondary filter. Next, the Air Fit uses a powerful high efficiency particulate air filter (HEPA) to remove up to 99.99% of particles less than one micron in size. HEPA filters are the highest known standard for air filtration technology and work by forcing air through a randomly aligned mesh of incredibly fine synthetic fibers to catch any particles trying to travel through. By the time air leaves the filter, it is fully purified and ready to be circulated into your cleanroom or facility. As air is purified and released, the motorized fan is blowing air to create a higher flow.

Supply Purified Air

Aeroex fan filters offer significant benefits for those wishing to establish clean rooms and airflow regimes that meet ISO 14644 certification, or those who simply wish to get the full benefits of air purification and flow. Fan filter air purification can virtually remove common environmental risks such as the heightened prevalence of microbiological contagions. In other scenarios, clean rooms require the elimination of dust and other particulates that can interfere with intricate production processes (e.g. nanotechnology) or would introduce impurities in strictly regulated substances (e.g. pharmaceuticals). 

How to Choose A Fan Filter

Cleanroom technologies like Aeroex’s AIR FIT and ISO 14644 certification are generally understood as having many of the benefits listed above. Nevertheless, choosing a fan filter unit requires careful consideration. Air purification and removal of the smallest particles are foundational to ISO 14644 standards, making a purification system the logical starting point – in this area, Aeroex’s designed and made-in-Canada technology delivers by producing high-quality filters with a large volume of filter media.

After setting performance and specifications, you may not have considered the ongoing operations, configuration, and maintenance costs. Here, Aeroex has made specific research, design choices, and investments that will deliver value for your fan filter across its entire lifecycle. Consider the filter replacements – many competitor products create unexpected expenses due to frequent filter maintenance (e.g. clogging) and replacements. Aeroex lowers your costs in the medium-long term by using high volumes of filter media to extend the life of the filter until replacements. The volume and primary mechanical filter are also meant to prevent clogging. Our clients report filters performing past their 1 to 3 year expected service life. Competitor products may require a filter change as soon as every six months. The Air Fit also delivers stronger airflow despite being smaller than competitor products, thanks to Canadian engineering.  

Clean Room Installation

Most importantly, Aeroex has also designed the Air Fit to avoid costs specific to cleanroom configuration and airflow engineering. To provide a clean room, balancing, and certification from an airflow technician is required after design and deployment. Larger cleanrooms often have multiple fan filters, requiring each one to be individually inspected and balanced. This can become highly costly once technicians have to work at heights and provide individual attention (and billable hours!) to each fan filter. Luckily, the Aeroex Fan Fit comes with a central control panel that can configure and operate multiple units remotely – significantly streamlining the balancing process!

Supply Purified Air

Fan filter units are the best way to supply your clean rooms and facilities with purified air at sufficient flows, and Aeroex’s Air Fit is uniquely designed to provide the most value for air purification. Contact Aeroex today to learn how to get started.


Air Purification

Fan Filter Unit for Clean Room

Clean rooms are special facilities with engineering controls to prevent contamination from vectors like airborne pollutants. Clean rooms are important because they ensure the safety and integrity of critical applications and industries like manufacturing quality control, or the production of pharmaceuticals and medical supplies.  Special industries using cleanrooms include specialized optical devices (ex. cameras and telescopes), production of personal protective equipment, food production, fuel cells, military applications, and academic research or experiments (per Terra Universal). In any cleanroom, purified air is one of the most important parts of meeting the required standards. Recognizing this need, Aeroex provides ceiling mounted fan filter units with the airflow capacity, medical-grade filtration, and flexible configuration options to create a cleanroom air purification system.

Which Type of Filter Should Be Used to Filter The Air Entering a Clean Room?

Clean rooms are measured and defined by the levels of airborne particles within the controlled environment. Clean rooms have many other considerations like the usage, entry points, design, etc., but these factors all contribute or relate back to the permissible level of contamination. This is recognized by the ISO 14644 series of standards for Cleanrooms and Associated Controlled Environments (some cleanroom users like American industries also reference Federal Standard 209).

Per the International Standards Organization, clean rooms fall into one of nine categories of cleanliness based on the maximum allowable density of sub-micron sized particle contaminants in the cleanroom air. A logarithmic scale is used to delineate cleanliness levels. Different industries may require varying levels of cleanliness – for example, a general pharmaceutical manufacturing cleanroom may require an ISO-8 standard (15–25 air changes per hour and a maximum allowable concentration of 3,520,000 0.5 um particles / cubic meter), whereas a pharmaceutical clinical trial may require an ISO-7 standard (30–60 air changes per hour and a maximum allowable concentration of 352,000 0.5 um particles / cubic meter) (Source: Mecart Clean Rooms). Fan filtration with adequate capacity and performance is critical to meeting these requirements. The highest standards may require additional measures, such as unidirectional flow or an airlock system.

Aeroex understands the unique parameters that define clean rooms that go beyond general standards for air quality referenced by OSHA, the EPA, and other industry bodies. Aeroex’s understanding of cleanrooms is also supported by other standards-related but not captured by ISO 14644, such as standards for the measurement or distribution of airborne particle sizes. Aeroex has designed a fan filter for clean rooms with this technical understanding as the foundation.

How To Make a Clean Room With Air Purification

Clean rooms are not possible without several design factors. The cleanroom also needs to enable the end-user, such as manufacturing. The method of establishing a clean room will depend on the size and configuration of the facility but generally includes a few key items – notably air purification systems. A cleanroom is achieved with the following inputs (Source: Trax Industrial):

  • Air purification systems: a cleanroom must be void of dust, aerosols, vapors, smoke, microbes, and other contaminants suspended in the air that could interfere with quality or processes. To achieve ISO standards, air filtration must target particles smaller than one micron, like Aeroex’s fan filter devices.
  • Positive air pressure: to promote the flow of air and the proactive extraction of contaminants, positive pressure needs to be enforced. This quality measure ensures that if the cleanroom were compromised, the higher pressure air of the cleanroom would push air towards the breach rather than drawing unpurified air into the cleanroom. This means any air purification system needs sufficient air handling.
  • Exfiltration: To sustain a positive air process, the room must be properly sealed. As much as possible, escape from windows, doors, electrical conduits, and other pathways must be eliminated.
  • Environmental factors: Humidity, temperature, conductivity, and laminar (smooth) airflow are all required considerations for a proper cleanroom.

Aeroex understands the pivotal role that air purification systems serve in making a clean room, and has designed its fan filter units to provide the necessary performance and filtration specifications to eliminate contaminants while maintaining positive air pressure.

Fan Filter Unit for Clean Room

The Air Fit is a fan filter unit for clean rooms and other facilities providing air purification. Air Fit integrates with your existing mechanical systems to deliver more airflow and clean room air purification simultaneously. The Air Fit is light and compact, fitting onto the ceiling with the existing ventilation. Once installed, it purifies the air with a two-stage filtration system.

Why are HEPA Filters Used in a Cleanroom?

Aeroex HEPA filters meet the highest standards for efficiency and purification. The primary filter removes large particles to minimize impacts to the second stage high-efficiency particulate air filter (HEPA). The secondary HEPA filter provides 99.99% efficiency for particles as low as 0.3 microns – this standard meets or exceeds many of the cleanroom classifications set by ISO 14644. Aeroex provides high-quality filters within this system that lower your operating costs, using large volumes of filter media to extend the service life until an eventual replacement – the primary filter is also designed to reduce wear on the secondary filter.

Ceiling Filters for Clean Room Requirements

Filtration efficiency is only one determinant of a proper cleanroom – systems also need to deliver adequate capacity for positive air pressure and many exchanges per hour. The capacity needed will depend on the size and configuration of the room. To meet different needs, Aeroex provides the Air Fit 500 as an entry point to deliver 500-600 cubic feet per minute of airflow, with the larger Air Fit 1000 Clean Room System delivering up to 1100 cubic feet per minute.  

Aeroex understands the specific needs of fan filter units for clean rooms. A larger air exchange volume may be needed to meet higher levels of cleanroom certification. In these situations, there are two general approaches – a larger unit and/or several smaller and supplementary units could be deployed. To ensure you meet ISO certification, Aeroex provides a central control unit with the Air Fit 1000 for operation by an air balancing engineer who will measure and configure airflow. Controlling all units from a single panel creates a safer and more efficient balancing process, rather than working at heights to modify and balance several units individually. This is one example of how Aeroex is committed to the full lifecycle of your cleanroom operation and continued ISO certification.

Fume Extraction with Activated Carbon

Treating Fumes with Granulated Activated Carbon

Granulated activated carbon is commonly used as a filter media to remove harmful fumes, odors, and gaseous compounds to improve indoor air quality. 

Humans have been using carbon filtration for thousands of years. Ancient Egyptians were the first documented to have used carbon medicinally – to remove odors as the result of infection. Before this, it was used in the manufacture of bronze to remove impurities. Gas masks manufactured in WWI used charcoal filters to remove some of the deadly gases used in combat. 

Today, a primary usage for granulated activated carbon is in work environments where limiting exposure to toxic fumes can prove difficult. Effectively treating and removing fumes can mitigate the negative outcomes that are the result of long-term exposure – thereby protecting the health of a facility’s personnel and staff. 

Activated carbon is an effective filter media for removing harmful fumes and gases due to its ability to remove volatile organic compounds (VOCs) and other pollutants from the air. Activated carbon achieves this through the process of adsorption in which pollutants are trapped outside the pore structure of the activated carbon granules. 

In today’s post, we discuss in-depth everything you need to know about treating fumes with granulated activated carbon – including what it is, how it works, and what options are available to you based on your needs.

What is Granulated Activated Carbon?

Carbon (also known as charcoal) refers to what is left behind after incomplete combustion. Industrial processes of manufacturing activated carbon occur in a 2-step process. First, material from wood, coconut shells, or coal is carbonized in a vacuum until all organic compounds are volatilized – leaving behind the carbon. 

Next, high-temperature steam, air, or carbon dioxide is applied to “activate” the carbon. This makes the carbon more porous and vastly increases its surface area – allowing an increased number of places for which gas molecules can be trapped.

How does granulated activated carbon work?

Granulated activated carbon effectively filters harmful pollutants from the air via adsorption. 

This process is different from the similarly named absorption. The key distinction between adsorption and absorption is that in the process of adsorption – pollutants adhere to the outside of the carbon. This is in contrast to absorption, where pollutants are absorbed within the structure of the substance much like that of a sponge.

Activation of the carbon expands its surface area which is what enables more pollutants to adhere to the outside of the carbon in the process of adsorption. 

Why do we use granulated activated carbon to treat fumes?

Granulated activated carbon has proven to be effective at removing odors, impurities, and harmful gases historically so it would make sense (and there’s science to prove it) that it would make for an effective filter media to treat against harmful fumes and gases.

The vast surface area of activated carbon makes it a more effective filter media than other substances as the larger surface area creates more surface tension, thereby promoting adsorption of harmful gases to its surface. 

Granulated activated carbon filters are effective where other filters are not at removing harmful fumes and VOCs from the air. They will typically feature a bed of activated carbon to trap gases and harmful fumes to improve indoor air quality. 

There are some gaseous substances that some mechanical filters are ineffective at trapping. Mechanical filters are unable to remove unpleasant odors – so it is often the case that carbon filters are used in tandem with mechanical filters that remove fine particles from the air, to improve indoor air quality overall. 

Activated Carbon Filters in Commercial Places

In manufacturing facilities, regular exposure to harmful fumes can be difficult to mitigate. Depending on the types of substances being used in different manufacturing processes, exposure to fumes can negatively impact the health of facility staff and personnel. As such, a powerful and effective filtration solution needs to be in place to improve indoor air quality. 

This is where the use of carbon filters can come into play. While many facilities may already have existing and effective dust or mist collection systems in place, the mechanical filters used in these systems are unable to properly filter out harmful gases and fumes. 

Granulated Activated Carbon Solution for Your Unique Needs 

There’s no question that minimizing exposure to harmful fumes is paramount to ensuring the health and safety of your shop personnel. It is for this reason that Canadian-based Aeroex Technologies has engineered a solution capable of effectively removing harmful fumes to improve the indoor air quality of your work environment. 

The Aeroex team of professionals will assess your facility’s unique needs to offer a tailor-made solution for fume treatment in your indoor work environment. Models in our IRIS series of medical-grade air filtration systems are equipped with a dual-stage, high-performance odour control MERV8/carbon primary filter as well as a second-stage HEPA filter to effectively mitigate the impact of exposure to harmful fumes via ambient or source-capture filtration.

Air Purification

Air Filtration System for Wood Shop

An overlooked hazard in any industrial woodshop is toxic fumes that come from the woods and the products you work with. Regardless of whether you operate an industrial woodshop or are a casual hobbyist, the danger of long-term exposure to toxic fumes from the wood you work with should not be taken lightly. 

In today’s blog, we further discuss the impact of toxic fumes in the woodworking industry and how Aeroex Technologies offers an engineered air filtration system that is capable of reducing toxic fumes from your woodshop facility.

Health Risks Associated with Toxic Fumes from Woodworking 

Wood Processing Fumes 

Exposure to toxic fumes can come directly from the constituents of coniferous trees such as cedar and pine woods. Wood dust particles is considered a Group 1 carcinogen according to the International Agency for Research on Cancer (IARC). Specifically, exposure to fumes from wood dust particles can result in health issues due to the natural chemicals of the wood and substances in the wood i.e. bacteria, molds, pesticides, and fungi being released into the work environment as fumes. 

Wood dust particles emit fumes in woodworking processes such as sawing, routing, sanding, and other operations, freeing microscopic particles into the shop that can irritate the eyes, noses, and mouth of your shop personnel. Toxic effects will range depending on the species of wood. 

Long-term exposure to cedar and pine wood fumes can exacerbate the symptoms of respiratory conditions such as asthma, and in some cases, can result in the permanent damage of lung tissue. According to the Canadian Centre for Occupational Health and Safety, Western red cedar, in particular, has been proven to contribute to the development of asthma. Plicatic acid is a common allergen and exposure to red cedar wood dust that contains this acid is what can cause an asthmatic reaction.

Case Study: Dundalk Leisurecraft 

Aeroex Technologies offers the expertise needed to ensure that the toxic fumes emitted from woodworking businesses are reduced in the working environment. 

Canadian manufacturer, Dundalk Leisurecraft specializes in building rustic, solid wood indoor and outdoor furniture, saunas, tiki bars, gazebos, and more – all constructed from maple, pine, and cedar. Dundalk reached out to our team about finding a solution for dealing with the toxic fumes that were being emitted into their work environment – specifically, from working with red cedar. 

Dundalk had a working dust collector in place, but their shop personnel were experiencing some of the symptoms associated with toxic fumes from wood dust. Their existing dust collector system was effective at collecting wood dust particles, however, it was also circulating toxic fumes from the wood dust around their facility. They needed an air filtration system that was able to mitigate the exposure of their shop personnel to these fumes. 

The Aeroex team of professionals assessed their shop needs and installed 2 IRIS-200 Air Purification Units that use activated carbon filters for ambient air filtration to remove the fumes in their workshop and keep the air clean. After the installation of the IRIS-200 Air Purification Units, the Dundalk staff noticed that the smell of the toxic fumes, as well as their symptoms, were substantially reduced.

Wood Smoke 

Some woodworkers finish wood using fire in their facilities to create a sought-after charred wood or shou sugi ban inspired effect – however, finishing wood with fire can leave woodworkers exposed to the negative health implications of wood smoke. 

Wood smoke is notorious for containing thousands of irritants and carcinogens such as polycyclic aromatic hydrocarbons (PAHs) and Benzopyrenes – both of which are toxic to humans. Like the effects of exposure to wood dust, exposure to wood smoke can cause eye, nose, and throat irritation in addition to headaches and nausea. Long-term exposure to wood smoke can also worsen the symptoms of existing respiratory conditions such as asthma.

Case Study: Montreal Bagels 

Montreal-style bagel businesses authentically produce their bagels by hand and in-shop. Using wood-fired ovens to cook these bagels is what gives them their notable flavour. However, the untreated wood smoke released from these ovens can lead to large environmental and health issues without an air filtration system. 

Luckily, Aeroex Technologies offers experience working with Montreal-style bagel businesses that use wood-fired ovens to produce their bagels. Our line of IRIS and ARO air filtration systems can keep wood smoke emissions at bay – mitigating the environmental and health risks associated with their untreated release.

Wood Treatment and Finishing Products 

Wood treatment and finishing products commonly used in a woodworking shop can also lead to health issues. 

In wood treatment, there are certain pesticides used as preservatives to maximize the service life of the wood. Small amounts of treated wood chemicals can escape or leach from the treated wood. The number of pesticide chemicals released from the wood will depend on a few factors. However, working with treated wood in a shop will exacerbate the release of these chemicals into the work environment as wood dust fumes – exposing you and your personnel to its effects. 

Wood finishing products such as oil-based stains, varnishes, and shellacs emit fumes that contain harmful volatile organic compounds (VOCs) that can degrade the quality of air in the shop and negatively impact human health. Breathing issues, nausea, dizziness, eye and throat irritation, and headaches are all potential symptoms of exposure to the VOCs in the fumes when using these products. Long-term exposure to these products’ toxic fumes can also result in wood stain poisoning with symptoms that include a burning sensation, blurred vision, and collapse, and cancer in more serious cases. 

If you’re concerned about exposure to toxic fumes from wood treatment and finishing products in your woodshop, consider Aeroex’s line of IRIS air purification systems. As in the case of toxic fumes from wood processing, IRIS purification systems utilize activated carbon filters for ambient air cleaning to remove toxic fumes and improve indoor air quality in your workshop.

Air filtration system for Toxic Oil Fumes in Woodshop

As you can see above, there are a myriad of ways in which exposure to toxic fumes can occur in the woodworking industry. Long-term exposure and improper precautions to fumes from wood processing, wood smoke, and wood treatment and finishing products can negatively impact the health of you and your shop personnel.

It is for this reason that a proper air filtration system is in place to remove the presence of these particles and protect you and your workers from the long-term effects of exposure to toxic fumes in the woodshop. 

Aeroex air purification solutions target toxic fumes that are common in many woodworking facilities. We use multi-stage filtration techniques that target the sources of air quality issues. Our systems are designed to capture the smallest particles with the highest efficiency, and our made-in-Canada devices are designed to maximize the lifecycle of your filters (important given the volume of toxic fumes produced in large-scale woodworking operations). 

Models in our IRIS and ARO series are capable of mitigating the impact of toxic fumes using ambient or source-capture filtration. Aeroex offers the ability to augment any existing ventilation systems you have with an air filtration solution. This can be an option when you already have some mitigation measures in place at the source, but wish to improve the working conditions across your shop. 

Given the various options and models, we recommend that Aeroex get to know your operation to make a recommendation about the most affordable and efficient options. With over 20 years of experience and a variety of filtration media to choose from, we can assess your woodshop’s unique needs and offer you a tailor-made solution to remove toxic fumes from wood processing, wood smoke, and wood treatment and finishing products from your facility.

Reopening Businesses Safely With Air Purification

Reopening Businesses Safely With Air Purification

Businesses are still navigating the unknown of operating in the face of the COVID-19 pandemic, with changing public health policies and an evolving body of knowledge about the transmission of airborne viruses. Many workplaces have likely had to deal with some positive cases among their workforce, disrupted supply chains, or an abrupt change in reopening plans. With the economy entering new stages of reopening thanks to reduced case counts and increasing vaccination rates, there is now a need to pivot towards increased utilization of public spaces. The most successful businesses in this time will be those able to seize the opportunities of the new economy. Because COVID-19 and its variants cannot be eliminated altogether it is understood that reopening will carry residual risks related to the virus, and various methods of screening those COVID-19 risk factors are needed. As gathering restrictions are reduced and more workers and customers return to public places, new risks will emerge related to COVID-19 transmission and heightened expectations for workplace safety. Improving the ventilation of your business or public space with air purification will be a critical part of successfully adapting to this reality. 

Air Purification – Part of a Reopening Strategy

For a business owner or facility operator, there is no “silver bullet” to reopen. Instead, a suite of measures is needed to eliminate or mitigate the different threats of COVID-19. This is true for restaurants, shopping malls, offices, schools, medical centers, and other gathering locations. Air purification will be an important strategy when paired with other measures such as mask-wearing, social distancing measures, or hybrid work arrangements. Air purification will significantly reduce the risk of airborne COVID-19 transmission but is not a replacement for other public health measures or workplace best practices. The combination of strategies that you use in your workplace will depend on your operations but are likely to include a portable or industrial air purification solution given its effectiveness in reducing the transmission of airborne viruses. For example, check out our case study below on why the Ontario government is using HEPA filters like Aeroex’s as a way to scale back mask-wearing policy for low-risk cohorts.

What To Know About Air Purification for COVID-19 

Improving indoor air quality is a key way to reopen business safely because of how COVID-19 is transmitted. Per the CDC, viruses like COVID are transmitted when a contagious person breathes out droplets and very small particles that are carried through the air to recipients. Infections occur when this air is breathed in or received by other vectors. However, as reported by sources like the New York Times, medical-grade air purifiers (like those produced by Aeroex) with a HEPA filter can capture these small particles highly effectively. Particles that cause the virus are around 125 nanometers in size while a HEPA filter captures particles as small as 10 nanometers (the HEPA standard is 30 nanometers but a recent NASA study showed its highly effective past this). Therefore, deploying HEPA filter air purification systems like those produced by Aeroex in your workplace is an excellent strategy. Understanding the science of air purification and the root causes of COVID-19 transmission, buyers should be aware of claims from other technologies like UV lights that don’t prevent transmission – evidenced by recent controversies like the UV light recalls ordered by Health Canada.

How to Know What HEPA Filter To Use for Air Purification

While science shows the power of HEPA filters, the way they are deployed is important for success. There are many different public spaces in need of protection ranging from condo lobbies to the storefront of an independent business – in each case, the existing ventilation, air volume, and gathering size will be different. To prevent transmission, air needs to be purified at a rate that prevents particles containing the virus from staying too long in the air – this is measured by something called air exchanges per hour. To prevent transmission, an air purification system catered to your space must provide sufficient air exchanges. Aeroex is aligned with the ongoing research recommending ~6 exchanges per hour and uses tools like our volume calculator to propose the appropriate model with sufficient capacity. It is important to ensure that the HEPA filters used to provide this air exchange capacity, either using a larger unit or several small units where a large unit is not possible. Many companies claim to provide the HEPA efficiency, but not with the air exchanges you need. When deploying for locations with large open rooms, Aeroex typically uses models like our IRIS 4500, a unit that mounts into your existing ventilation systems and provides a primary MERV 8 carbon filter and a secondary HEPA filter with an efficiency rating of 99.97% at 0.3 microns. Other strategies include leveraging existing mechanical ventilation and choosing the right locations inside the room. If you do not have mechanical ventilation, we will help you to see a portable (non-mounted) model.

Case Study – Provincial Government Deploys 70,000 HEPA Filters in Ontario Schools

Medical grade air purification systems with HEPA filters like those designed by Aeroex are widely accepted as an industry best practice, which is why the Province of Ontario continues its deployment of HEPA filters in schools. To date, 50,000 have been deployed and another 20,000 are being deployed in time for the 2021 school year (as reported by Global News). The Province wishes to enhance the safety of schools and prevent the spread of COVID-19, using HEPA filters as part of a range of policies and measures. The Province is using air purification systems to enhance mechanically ventilated classrooms, as well as to provide standalone coverage in areas like cafeterias and gymnasiums that do not have mechanical ventilation. In the announcement by Minister of Education Stephen Lecce, highlights relevant to the case study included the following:

  • It’s another added layer of protection that recognizes that our youngest learners in this province will not be required to wear masks” – Stephen Lecce, Minister of Education
  • “Standalone HEPA filter units should be used in places where mechanical ventilation and improvements to ageing HVAC systems was difficult to achieve” – Ontario’s COVID-19 Science Advisory Table

Aeroex is a proud contributor to the fight against COVID-19 and high-quality classrooms for Ontario children. Our IRIS system is popular among public workspaces and institutions, including education, medical, government, and commercial buildings. Even before COVID-19, hundreds of our units were deployed in school boards, colleges, and universities across Ontario (we are an Ontario Education Collaborative Marketplace approved vendor). This has only increased due to the increased business case for deploying HEPA filters.

Air Purification

Industrial Odor Removal

Industrial odor control is a key determinant of a safe and healthy workplace and an indicator of the quality of your facility operations. In some industries, odors are a natural and important part of the business – examples here could include composting, cannabis cultivation, industrial food production, or wastewater treatment. In others, odors may arise as a result of equipment malfunction, incorrect batch ingredients, or other operational issues.

In each case, the odor has a direct impact on the products you distribute, the services your facility provides, and the way your staff and customers interact with your workplace. Odor is not always the first thing that comes to mind when industrial air purification is considered – often, issues like visibility, inhalation, and related safety concerns are top of mind. However, after consideration, it is clear that industrial odor control is necessary to maintain a safe and successful business. Therefore, attention should be paid to understanding your odor challenges and translating them to industrial odor control solutions.

Causes of Odor Issues

Odors are caused by volatilized chemical compounds traveling through the air. Typically, more volatile compounds have stronger bad smells. We smell odors when particles enter our nose, which usually occurs when odor molecules freely move through the air via diffusion (random movement in all directions, with a net flow from high concentration source areas to low concentration receiving areas). Sources of odor molecules may include cleaners, building materials, and aerosols. These particles tend to be incredibly small.

Odor control has been a source of some debate with 2020’s need to manage the COVID pandemic – some of the basic COVID control measures like masks do not mitigate odor – this is because odor particles are much smaller than those that cause COVID! Therefore, filtering the odor molecules that cause odor must be scaled to the causes of the odors themselves. Aeroex has a strong foundation in the science of odor causes and controls and has created an industrial odor control system (odor eliminator) matched to eliminate odors

Eliminate odors with our industrial Odor Control Solutions

The IRIS Series Medical Grade Air Filtration System optimizes indoor air quality, providing clean air by capturing the particles that cause odors, allergies, and other undesirable airborne contaminants like aerosols, particulate matter, microorganisms, and the previous discussed volatile organic compounds (VOCs). It accomplishes this through a highly engineered solution, recognizing that the particles that cause odor tend to be incredibly small (discussed above). Therefore, the filtration technique used needs to be small enough to eliminate those particles.

Our industrial odor control solution uses two progressive, powerful filters for removing odors. The first filter in the IRIS series is made of activated carbon, and as our primary filter, it has a MERV 8 rating (it will be followed by an even stronger filter in the second stage). Carbon fiber is an excellent odor eliminator because of its distinct ability to adsorb the particles it interacts with, chemically reacting and sticking to the filter. This is an important technique for odor control because it targets the root causes of odors rather than the odor itself. MERV 8 filters are excellent at targeting particles in the range of 3 to 10 micrometers – particles in this range typically include mold spores, dust, and cleaners – also known as the particles that commonly cause industrial odors!

The second stage filtration in the IRIS commercial odor eliminator machine is a high-efficiency particulate air (HEPA) filter with a 99.97% removal efficiency for particles with a size of 0.3 microns. This is the highest standard for air filtration systems and is referenced by guidance documents from leading organizations like the CDC. By removing larger particles first with the MERV 8 filter, the HEPA filter is then able to target the smallest particles that cause industrial odor.

To eliminate industrial odors you need an odor eliminator that efficiently filters the smallest particles, and the Aeroex commercial odor eliminator machine can do this at scale. Aeroex provides a range of models that are portable or can be centrally mounted, allowing you to employ source control solutions that are targeted odors nearby or ambient solutions that integrate into an existing HVAC system. The size of the unit will depend on the volume of your facility. Additional consideration could be given to how frequently you wish to cycle the air. Larger odor eliminators are often used where industrial odors are commonly associated with the workplace and occur throughout the building, such as a waste collection facility. Aeroex staff will advise on what unit is most efficient for you based on your operational context, but as a starting point check out our air purification requirements calculator for the IRIS system.

Trap odor molecules and Secure Your Workplace

Industrial odor control is an important issue, but the 2020-2021 pandemic has taught us that there are many other reasons to be concerned about indoor air quality in workplaces and public spaces. While industrial odor eliminators do not supplement government or public health guidelines, the medical grade status of the IRIS system means that it will minimize the presence of airborne infectious diseases, including COVID-19. The IRIS system is popular among public workspaces and institutions, including education, medical, government, and commercial buildings. Aeroex is proud to be able to support the efforts to fight COVID-19, with hundreds of our units being deployed in school boards, colleges, and universities across Ontario.

Evident from the discussion of the health benefits of medical-grade air purification is that there are many reasons to adopt an industrial odor control solution. As our awareness of workplace safety increases, so too does the need for air purification systems that attack the root causes of odors by filtering out the smartest particles. Aeroex achieves this while delivering a level of efficiency that helps to make an IRIS system a sound investment – our primary filters last 6 months and our HEPA filters last 3 years. The progressive filtration stages not only provide contaminant removal performance but also minimize the frequency by which you have to replace your HEPA filter.

Air Purification Manufacturing

3D Printing Fume Extraction

Three-dimensional (3D) printing is an increasingly popular technique for prototyping and additive manufacturing. The  ever expanding number of applications for 3D printing technology means the industry is expected to increase from $0.7 Billion in 2019 to $5.6 Billion in 2026. 3D printing can use a variety of materials including plastic, resin, ceramics, wood, metal, graphite, nitinol, and paper. Due to the diversity of 3D printing applications, the scalable nature of 3D printing technology and the rapid growth of the industry, every 3D printing company is likely to hit a point where the need for fume extraction becomes apparent. Similar issues surrounding fugitive fumes caused by various production and fabrication processes exist in comparable industries like laser printing, laser etching and laser cutting to name a few. For the majority of these industries, there is an alarming lack of awareness and education revolving around the negative health impacts attributed to fugitive fume inhalation in the production phase. Even though 3D printing is a fairly new idea, fume extraction is not. For more than 20 years, Aeroex Technologies has been at the forefront of developing mist and fume extraction products for the industrial and commercial sectors. With decades of experience and expertise in air purification systems, the team at Aeroex was able to modify and improve on already highly efficient filtration technology to meet the specific needs of the 3D printing industry. 

Challenges of 3D and Laser Printing

With many institutional and DIY newcomers to the 3D printing realm, health and safety is becoming an increasingly discussed topic. To understand the health hazards associated with fugitive fume inhalation, we must first understand where the fumes come from. In the process of 3D printing, filament reels are melted by the printer as it moves along the pre-programmed path. While heating and melting the material, fumes are generated as a byproduct of the process. The composition of the fumes will depend on the material being printed. Some of the most common materials like thermoplastic polymers (e.g. ABS) are known to emit styrene, a suspected carcinogen that also causes headaches, drowsiness, and fatigue. Some materials can be substituted to reduce the toxicity levels of fumes, but this does not discount that fumes will be generated regardless of material. 3D printing often takes hours and even days to complete a project, with machines running for a long time to print each layer. 3D printing is an incredibly powerful and scalable technology, but output rates should not be limited by health and safety concerns and you should not have to downgrade your materials from durable thermoplastics to reduce the risk of these fumes. Instead, an air purification system designed for fume extraction in 3D printing will allow you to safely continue your prototyping or manufacturing work without compromise to productivity or health. 

Aeroex’s 3D Printing Strategy

Before proposing a solution for 3D printing fumes, the engineers at Aeroex spent considerable time researching  the nature of the fumes generated by 3D printing including the materials involved, equipment used, typical shop configurations, and the nature of the fumes released (composition and quantity). Much like our medical-grade air purification systems and/or mist extraction systems that are used  for other processes that generate fumes like CNC machining, we apply the principles of source capture  and ambient control. In the case of 3D printing, processes are usually quite modular and the sources of fumes are easy to pinpoint. Therefore,  the source capture method is bound to be highly efficient because fumes can be extracted before they enter the ambient conditions of your shop, which would require purification of much larger volumes of air at lower concentrations. Our attention to strategy and deployment planning is a key consideration when many other air purifiers cite the performance of MERV or HEPA filters without a plan for you to experience this level of performance.

The Right Filter for the Job

Beyond our overall strategy, the filters in question will ensure complete fume extraction during 3D printing or laser printing. For fumes like styrene which are associated with 3D printing, Aeroex uses activated carbon filters with a HEPA standard for particle size and efficiency. HEPA (also known as high-efficiency particulate absorbing, as defined by the US Department of Energy and the EPA), has an efficiency rating of 99.97% for particles as small as 0.3 μm. Typically, fumes exist in the particle range smaller than one micron, making the HEPA filter the optimal application for 3D printing. 

Commercial HEPA Air Filtration Systems with Activated Carbon

Activated carbon is a powerful technology that removes airborne gaseous chemicals through adsorption (adhesion of molecules to a surface without inducing solubility), which is why it’s a trusted part of sacred processes like the treatment of drinking water and wastewater. Activated carbon is also the focal point of Aeroex’s air purification systems design for fume extraction in 3D printing and laser printing. In an industry where claims about carbon are abound, Aeroex goes beyond the competition. We use real carbon made of coconut shells. While some companies will use small sprinkles of carbon in their filters so it can be cited in their product description, Aeroex goes as far as filling the filter media with small elongated pellets. During fume extraction, the air is pushed through the pellets to maximize the adsorption process, providing you with superior efficiency and long lasting filters.. The composition of our activated carbon and the sheer amount of it we use is a key reason to choose Aeroex, especially once you begin to understand the underlying “gold standard” technology of our products versus others who claim to provide fume extraction.

There are both established 3D printing practices in North America as well as quickly emerging companies that are still fine-tuning their processes. 3D printing companies are quickly realizing the need to focus on health and safety, but we would encourage you not to rush – instead take time to understand your fume sources and the purification technology. Some companies are offering “technologies” like bipolar ionizers, hydroxyl generators, and disinfectant foggers (as reported by outlets like Mother Jones and Colorado State University) that claim to be quick fixes, when in fact these will leave you at risk without the fume extraction you truly need. Due to the growth of 3D printing and the ever expanding variety of materials used for printing, the industry is still zeroing in on the best methods of industrial air filtration and ventilation, like our HEPA filters. 

We Are Committed to Supporting the 3D Printing Industry

Plastic Welding Fume Extraction

Plastic welding is a popular technique for assembling goods from plastic components or materials because it allows you to directly join two compatible pieces without relying on adhesives or fasteners. This technique often produces products with a seamless appearance due to the components all being the same plastic material, without joints or clamps. The surface of the plastic is usually melted with a hot air welding gun. Although, there are other techniques like acoustic vibration, friction welding, laser welding, and contact welding. These manual techniques are useful for small operations, while larger operations can scale up with automatic welding. With these technologies, many of the goods we use in our everyday lives can be produced fairly inexpensively. However, any production technique that involves melting plastic will produce fumes that raise health and safety concerns and operational issues like accumulating by-products on the facility’s equipment. 

Challenges with Fumes in the Plastic Welding Industry

Plastic welding poses some unique challenges for air quality due to the types of materials being used and their operating conditions. Typically, rigid thermoplastics like PVC are welded at air temperatures of around 350 degrees Celsius to avoid discoloration or scorching of the product. Unfortunately, the melting point of these plastics and the operating temperature of the equipment mean that the emissions produced are bound to contaminate the ambient air in the facility.. The following are a few indicators  associated with industrial fume emissions: 

  • Acrylonitrile butadiene styrene (ABS) is known to produce black smoke and soot flakes.
  • Polyvinyl chloride (PVC) produces black smoke.
  • Acrylics produce a lot of odor.
  • Polycarbonate (PC) produces yellowish smoke and soot.

In each of these cases, fumes are producing chlorine, styrene, and other harmful by-products that cause acute effects like irritated skin or eyes, nausea, and headaches – with chronic effects including cancer. The rate at which these toxins are released can vary with your operating temperatures, complicating matters further. A plastic welding operation that wants to scale up has to manage these risks to remain safe and sustainable. 

As mentioned above, plastic welding smoke is often dark and mixed with fumes (the finer solid particles). Suspended in these emissions are large and fine airborne solid particles produced by vaporizing and condensing plastic particles, causing the dark color. The transient state of these particles means that they do not remain vaporized or airborne. The result? Condensation of smoke and fumes from plastic welding, leaving behind waxy residues! Setting aside the health and safety concerns of the fumes, these residues will impact and clog your machinery and conventional HVAC systems – driving up maintenance costs and reducing the useful life of your assets. The variation of particle sizes from smoke and fume combinations means that a uniform approach will not mitigate all emissions equally.

Strategies for Industrial Air Filtration and Ventilation

The waxy fumes and smoke from plastic welding are a reality of the production process that should be managed effectively for both safety and the longevity of your shop. This unique challenge is where Aeroex’s air purification systems perform as advertised while some competing air purification systems fall short as they advertise high efficiency, yet provide insufficient airflow to fully mitigate the inbound emissions. To manage waxy residues, a special design is needed to prevent clogging. Otherwise, you will be stuck doing perpetual maintenance without realizing the true benefits you should expect from your air purification system. 

Aeroex’s industrial air filtration units use progressive filtration technology where each stage is designed to complement the shortfalls of the last, and ultimately results in longer-lasting filters as well as allows filtration of particulate sized emissions and emissions on the molecular level. . Typically, this is where other air purification systems fall short and get clogged as these systems rely on the filter itself without primary mechanical elements. While these air purification systems “perform” well when brand new or during demos, they don’t have a design that will sustainably deliver the service you need. 

Since waxy emissions are a reality of plastic welding, then, there needs to be a way to deal with them in a way that does not impact your maintenance budget significantly. Your competitors are likely dealing with the same issue, due to the nature of plastic welding emissions. The progressive filtration approach allows the wax to accumulate on the primary washable elements, keeping your consumable activated carbon and HEPA filters in an environment where minimal wax residue is able to get through. The primary filtration elements are easily removable and hand-washable, a periodic and very low-cost maintenance activity. This design choice was intentional because it will prevent you from having the frequent filter replacement costs seen in other competitor models.
