- 9-12 MERV – These filters are more efficient and usually offer the best indoor air quality improvement for residential applications.
What MERV rating is a HEPA filter?
MERV 17
All HEPA filters have a rating of a MERV 17 or higher. A HEPA filter with a MERV 17 rating will trap 99.97% of air particles that are 0.3-1.0 micron in size and an even better % of particles below 0.3 microns and above (HEPA filters are rated at their worst performance).
Can a HEPA filter stop a virus?
Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes.
