What MERV filter stops Covid?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.
What does MERV 16 mean?
A filter with a MERV rating of 13 to 16 captures particles greater than 0.3 micrometers. This includes bacteria, droplets from sneezing, smoke, and most other sources of pollution. This level of filtration is used in patient and surgery areas of hospitals.
Does MERV 16 restrict airflow?
While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow.

Can I use a MERV 16 filter in my furnace?
The problem is, most residential heating and cooling system aren’t rated to handle this much. That means, if you’re using a filter with holes that are smaller than recommended, you’re essentially plugging up your HVAC system. … This is why we almost never recommend MERV 16 filter for home-usage.
