How Does Air Filtration Work?

 

With the identification of the novel coronavirus, we began to rethink the safety of our workplaces and what factors would need to be adjusted in the “new normal”. Within this context, the need to consider air filtration in the workplace became widely apparent. 

 

In 2020, it quickly became clear that many of the existing industrial air filtration systems were ill-equipped in their ability to adequately purify the air, notably in institutional facilities and other public workplaces like schools or offices. This finding demonstrated the need for greater investment in air purification. Despite this need, agencies are increasingly being asked to meet rising performance expectations while making greater use of limited funds. This means that the ideal air purification solutions that are needed can effectively mitigate risk, align with public health practices, and demonstrate investment performance. 

 

Medical Grade Air Purification

 

Aeroex understands the need for medical-grade air purification. We are experts in the science behind the process and have designed products to match. First and foremost, for medical grade applications, the main threat is biological matter (which is millions of times larger than the atmosphere’s molecules), therefore the filter efficiency should be very high, generally falling under the HEPA classification. However, this strategy does not help with small molecules such as VOCs. To tackle VOCs, one highly effective technique that is available involves a material called activated carbon. Understanding this, Aeroex uses multi-stage filtration processes that have compounding efficiency benefits in each stage, finishing with medical-grade HEPA filtration. 

 

Air purification needs to effectively improve the safety of the workplace in areas where there may be low ventilation or few options for physical distancing whereby in-room filtration is needed rather than products like UV lights which do not improve filtration. Aeroex products provide assurance and risk mitigation, and our understanding of the science behind medical-grade air filtration has allowed us to engineer state-of-the-art air purification systems used in public workspaces across North America. In-room air purification technology has been proven to significantly reduce the spread of COVID-19 by organizations like the WHO. Commercial HEPA Air Purifier filters should be used as an additional control measure to reduce the risk of exposure to COVID-19 – while they do not guarantee the complete elimination of a virus or replace any government recommendations, the performance they deliver will provide you with balanced risk management that keeps your facilities operational.

 

Aeroex IRIS Commercial HEPA Air Filtration Systems

 

If you operate a school, office building, or another public setting like a doctor or dentist’s office, Aeroex recommends the IRIS Medical Grade Air Purification Unit as a device that embodies the science of air purification and the practicality of your operation. It is specifically designed for occupied spaces that will protect your students and staff. Consequently, hundreds of our products can be found in school boards, colleges, and universities across Ontario, Canada.

 

IRIS Medical Grade Commercial HEPA Air Filtration Systems are equipped with a dual-stage, high-performance odour control MERV8/Carbon Primary filter and a 2nd stage HEPA filter with an efficiency rating of 99.97% @ 0.3 μm. Our exchange ratings use CDC guidelines to provide airborne risk mitigation through high-grade air purification. The IRIS series includes both portable and central purification systems and offers several secondary benefits like variable speed control and high-performance odor control.

 

Many cheap alternatives make big promises about the performance of their HEPA filters, but leave out key details about the capacity, air flow, and compatible room size for in-room air purification. This is a big issue that Aeroex is trying to combat – The effectiveness of an air purifier is usually reported in terms of efficiency, which can be misleading, as it only tells half of the story. The other crucial factor to consider is air flow. Together these two factors equal the Clean Air Delivery Rate (CADR), which is a better measure of how a device will perform. For example, 99.99% efficiency may sound great, but if the air flow is only 20 cubic ft./min. (cfm), one would be better off with a purifier at 90% efficiency and 50 cfm (CADR: ~20cfm VS. 45cfm). If the unit is incapable of providing sufficient air exchanges for the space it is located in, the efficiency rating is borderline meaningless.n. Make no mistake, Aeroex will deliver not just on the promise of long lasting HEPA filters but the availability of multiple models capable of an array of air flow ratings will make certain that a proper solution is matched to your needs.. For proof, check out our live demonstration of the IRIS-400 Medical Grade Air Filtration System in action versus smoke in an unventilated room for a visual depiction of how quickly we purify your workspace. We have successfully purified air for clients like schools, dentists, hospitals, and commercial offices.

Aeroex Emphasizes Safety, Quality, and Trust

 

By purchasing an in-room air purification system, you are putting trust in a company and a product that will keep your visitors safe. However, many companies are exploiting the circumstances of the past year to mislead customers and distribute dangerous products. As recently as May 2021, it has been uncovered that thousands of best-selling air purification devices purchased by schools with government grants are producing toxic chemicals and do not work as intended. As reported by Mother Jones, one of the United States’ top manufacturers (Global Plasma Solutions) is now facing a $750 Million lawsuit from the State of Delaware, charging that company claims were “deceptive” and made the air worse due to the ions it discharged. Be skeptical of companies like Global Plasma Solutions who make claims of advent “technologies” like bipolar ionization. 

 

Aeroex has an established history of producing air purification systems well before the COVID pandemic. Our investment in efficient designs and our decision to manufacture our products in Canada are part of our strong commitment to valuing the trust you place in us. We strive for longevity and wish to gain your confidence through demonstrated results from tried-and-true technologies. Aeroex is a company you can trust to provide in-room air purification for your school or meeting space.  

 

Lower Total Lifecycle Cost

 

The maintenance requirements for your purification system should also be scrutinized – products with cheaper prices often rely on badly designed filters that need to be replaced constantly. The same way a printer company wants to sell you ink cartridges, many air purification systems want you to keep coming back for costly filter replacements. If you are hoping to upgrade your facility with an air purification system funded by a grant opportunity or similar one-time funding, Aeroex products are likely the better solution because they have lower operating impacts on your business in future years. Competitors often use a fraction of the filter media used by Aeroex, resulting in competitor drops in efficacy within a few months of application and increased maintenance costs from high filter changing cycles. Aeroex wants you to get the best value for your investment.

Air Filtration For Schools and other educational facilities.

Air Filtration For Schools and other educational facilities.

Air quality has always been important, however, it’s never been more top of mind than now! The current global situation has forced us to look at air quality in a different light, especially in enclosed spaces, such as educational facilities. Let’s dive into air filtration for schools.

Daycares, schools, colleges, and universities face unique challenges in keeping their air clean. Essentially, they are densely populated spaces in which people tend to spend extended periods of time, thus increasing exposure for students and faculty to air pollutants that may be present.
It is not uncommon to find dust, viruses, bacteria, allergens, and mold circulating in the air.

Our educational facilities should be clean and fit for learning. One way to reduce air pollutants and potential exposure to disease in classrooms and lecture halls is by using air purifiers. There are various options available, but essentially they all try to achieve the same result – clean air by neutralizing or filtering out contaminants.

What are Air Purifiers?

Air Purifiers are machines that either filter or neutralize airborne contaminants. They achieve this by employing various methods, but most can be classified in one of two ways: Filter driven air purification systems (such as HEPA air purifiers) or Needlepoint Bipolar Ionization, which neutralizes contaminants by ionizing the air.

HEPA filtration works by forcing air through a filter media, with numerous redirections in its path, causing 99.97% of microns smaller than 0.3 μm to be trapped. HEPA air purifiers are ideal for educational facilities as they are designed for use in occupied spaces, produce no byproducts, and can operate continuously with minimal maintenance.
Public Health Ontario has stated that “Air cleaners equipped with HEPA filters should be able to remove COVID-19 virus-sized particles from indoor air, which may contribute to a reduction in exposure to the virus.” (https://www.publichealthontario.ca/-/media/documents/ncov/ipac/2021/01/faq-covid-19-portable-air-cleaners.pdf?la=en)
