MERV-13 filters are engineered to effectively block impurities down to sub-micron levels (. 3 microns) with 99.97% efficiency. These filters offer the highest level of face mask insert filtration available, while maintaining breathability. … Thus, MERV-13 is considered by most to be the optimal face mask filter.
What does MERV 13 mean in air filters?
MERV stands “minimum efficiency reporting value” and a filter receives a MERV rating as determined by the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE). … A MERV 13 will trap less than 75% of air particles that are 0.3-1.0 micron in size (the coronavirus is 0.1 microns).
