Classroom Air Purifiers – Keeping Our Children Safe

COVID-19 sent our country into an unprecedented period of uncertainty. As schools begin to reopen and phase back in-person learning, it is important for our communities to ensure this is done safely. Masks, social distancing, handwashing, and manual sanitation efforts will still be enforced, but is there more that can be done? Classroom air purifiers are a must for keeping our children safe and ensuring a safe return to school. Below, the experts with Action Services Group detail the modern air purification technologies that can help reduce the spread of COVID-19 and other illnesses in classrooms.

Recommendations from the ASHRAE

Recently, the American Society of Heating, Refrigeration and Air Conditioning (ASHRAE) released a set of guidelines to help ensure the safe reopening of schools across the nation. Aimed at preventing the spread of COVID-19 amongst our student and teacher population, these guidelines can help protect your children, as well as your family, from transmissible illnesses that can devastate an entire population. Classroom Air Vents Recirculating infectious droplets One of the main reasons illnesses, including COVID-19, are spreading so quickly in schools and universities is due to the shared HVAC systems. These systems push and pull air from all different areas within a school, making it more likely to pass germs from a sneeze or cough in Classroom A to Classrooms B and C as well. However, thanks to modern technology, indoor air quality in these spaces can be greatly improved. While this will not take the place of proper sanitation procedures, masks, and hygienic practices, such as washing hands, it can help reduce the number of airborne pathogens.

Indoor Air Quality in Schools

By following the guidelines established by ASHRAE, schools can help to reduce airborne pathogens, thus helping to limit the spread of illnesses that may be inhaled. While social distancing, masks, and proper sanitation protocols are still required, this reduction goes a long way in helping to reduce the likelihood of cross-contamination. Schools and universities are made up of many different types of spaces. We understand it can be costly to add these protective measures to every single space within a facility. To help reduce costs, professionals recommend that the focus areas should be classrooms and the school nurse’s office.


Improving an organization’s ventilation effectiveness is one of the main guidelines experts suggest for all industries. In Improving Ventilation Effectiveness and Dose Reduction of PM 2.5, we discuss particle matter and the importance of dose reduction as it pertains to mortality rates.


Classroom Air Purifiers

Per the ASHRAE guidelines, experts recommend that schools use a combination of HEPA filters and air purifiers for the classroom. As these spaces are the primary areas of congregation, they become the first priority in combating the spread of COVID-19 and other illnesses. Our Halo Smart P filtration stations utilize a HEPA H14 filter, which traps virus-sized particles. These filters are for the most complex health situations. They effectively and significantly reduce the spread of all viral and bacterial pollutants, particulate matter, and allergens. These filters are the same as those used in laboratory microbiological safety cabinets for handling pathogenic microorganisms in total safety. ASHRAE recommends installing these air purifiers in each room to ensure maximum effectivity. Additionally, they recommend that each unit should be able to perform at least two total air changes per hour (ACH). Ultimately, the more air changes classroom air purifiers can make, the more effectively airborne pathogens disappear.

Improving Office Air Filtration for School Nurses

When children feel sick while in the classroom, they report to the school nurse’s office. As with medical facilities, these areas can be a hotspot for germs and cross-contamination. As such, ASHRAE recommended the school nurse’s office operate off a dedicated HVAC system. While this may not be possible, investing in an air purifier that has a higher rate of air changes per hour is ideal. In fact, whether the school nurse’s office has an independent HVAC system or not, ASHRAE recommends these spaces have HEPA filters and air purifiers to ensure maximum protection.


While the global pandemic has brought air purification systems to the forefront, we have been battling air pollution for decades. In Recognizing Air Pollution’s Link to the Global Burden of Disease, we take an in-depth look at PM 2.5, the impact of air pollution on airborne viruses (COVID-19), and the importance of establishing a long-term mitigation plan.
