Serving Clark County & Portland-Metro Area
As we social distance and practice healthy habits during the COVID-19 pandemic, some of you may have concerns about possible aerosol transmission and what you can do to your HVAC system to help limit the spread of the virus.
Can an Air Filter help stop the spread of COVID-19 in the home?
Air filtration is only a small part of a solution against COVID-19. It doesn’t address surface contamination or contamination between individuals. However, in addition to frequent hand-washing, disinfecting, and social distancing, some air filters, air purifiers, and air cleaners may also help.
It all comes down to particle size and a filter’s ability to capture those particles effectively which can be determined by its MERV rating. The higher the MERV rating number, the better the filter is at filtering particles.
Size of SARS-CoV-2
Researchers say the virus that causes COVID-19 is about 0.125 micron in size. So this is something to consider when researching COVID air filters for the home. MERV rating is also important.
HEPA Air Filters for COVID-19
HEPA or high-efficiency particulate arresting, are filters that are designed to trap particles including allergens, mold, pet dander, and dust particles. The coronavirus is at the lower end of a HEPA filter’s range at 0.125 microns so while it could trap some particles, others may still filter through.
Electronic Filters for COVID-19
Electronic air filters are designed to electrically charge any particles that get passed a prefilter. Electronic filters are ozone-generating products that in the past have been successful against SARS, another coronavirus. It’s not certain, that it will effectively kill COVID-19.
UV Lights for COVID-19
UV lights are also important to mention as some air filters use this technology. UV lights don’t filter particles, rather they kill viruses, mold spores, and bacteria that are in the air. UV lights in homes are installed somewhere in your HVAC system where the rays will not directly shine on anyone. UV lights have been effective in killing MERS and SARS. To learn more about UV radiation and its effectiveness on SARS-CoV-2 Coronavirus take a look at this informative article from the FDA.
