Air Purification and Covid-19
Will Air Purifcation systems kill viruses?
With talk of coronavirus blanketing the airwaves and so many companies claiming to have special filters and air purifiers that can kill the virus, it’s no wonder we’ve received so many calls and emails from customers looking to protect their families and employees from this new illness, so we wanted to pass along some information to help you separate the signal from the noise.
Let’s start with the basics, according to the Centers for Disease Control and Prevention (CDC), coronavirus (COVID-19) spreads mainly through respiratory droplets produced when an infected person coughs or sneezes. It’s possible to get COVID-19 by touching a surface that has the virus on it, then touching your mouth, nose or eyes, but this is not thought to be the main way the virus spreads.
Noting that airborne particles play a significant role in the spread of the disease, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has released proactive guidance that addresses COVID-19 concerns with respect to the operation and maintenance of HVAC systems.
You should know that viruses, like COVID-19, are much smaller than bacteria (roughly 100 times smaller) and other pollutants like pollen and pet dander which are the primary culprits when it comes to poor indoor air quality. This means that a standard HEPA filter will not remove viruses from the air.
Unlike air filters, some air purifiers can capture viruses, but they won’t destroy them so the virus will remain alive inside the
