The particular strain of coronavirus that’s causing COVID-19 (known as SARS-CoV-2) measures between .05 and .2 μm in diameter. Typically you have a MERV 8 — MERV is a rating system for filters — and those capture less than 50 percent, it could be down to 20 percent of small particles. When used as final filters, they are the primary filters for an HVAC system. In comparison, an N95 mask goes a step further and must filter out at least 95% of particles smaller than 0.3 µm. This multi-filter system extends the life of the more expensive final filters, leading to overall cost savings. A PECO filter mightmake a difference, but only in a limited way. Building technology group ASHRAE has compiled recommendations for filtration, humidity set points, automation and more. A MERV rating of one is the lowest efficiency, with 20 being the highest.

Where possible, change to MERV-13 filters. If a MERV 13 filter is not a viable option in the HVAC system, then use the highest MERV rating you can. The diagram below demonstrates that MERV 16 filters trap up to 96% of virus-sized particles *, to help prevent the proliferation of airborne viruses in the home. Minimum Efficiency Reporting Value (MERV) MERV is a measure used to describe the efficiency with which particulate filters remove particles of a specified size from an air stream. Install MERV 8 or better filters. To remove coronavirus from the air, the U.S. Centers for Disease Control and Prevention recommends MERV-13 filters in schools, restaurants, office buildings and many indoor spaces. Coronavirus MERV 13 filters are also recommended in your home. What filter should I use to protect those in my building from COVID-19? Research has shown that the particle size of the COVID-19 virus is around 0.1 µm (micrometer). Filters like a MERV 13 get you closer to 80 or 90 percent, or HEPA filters capture 99.97 percent of particles, so upgraded filters can be effective. ", The health benefits of particle filtration are proportional to "the reduction in total exposure to particles less than 2.5 µm in diameter.
