Not Every Air Filter Can Protect You From COVID
The filter in an air purifier unit can capture airborne particles, but if it can capture an airborne virus depends on the virus’ size. For example, if the virus is larger than 0.3 microns (the size of most viruses), the filter will be able to catch it before it passes through your lungs and into your bloodstream.
If the virus is smaller than 0.3 microns, you’ll need a HEPA filter (or equivalent) with openings that are small enough for even small viruses to get caught in them.
What Is A HEPA Filter?
A HEPA filter is an air filter that can remove 99.97% of airborne particles. Particles that are larger or smaller than 0.3 microns are trapped with even higher efficiency; this includes viruses, bacteria, dust, pollen, and pet dander.
HEPA filters are highly effective because they have microscopic pores that trap these particles as air passes through them. Therefore, unlike other filters for air purifiers, HEPA filters can effectively remove SARS-CoV-12 from the air in your home.
Why You Need A HEPA Filter In Your Home Air Purification System
If you want your home air purification system to be effective at removing harmful airborne viruses, it’s essential to make sure it has a HEPA filter. HEPA filters are the most effective air filters to eliminate these particles from the air.
If you or someone in your home suffers from allergies, asthma, or other respiratory conditions, having a HEPA filter for your home air purification system is even more important.
