What MERV rating is HEPA?
17 to 20High-Efficiency Particulate Air (HEPA) filters are not MERV-rated, but a HEPA filter is typically considered as MERV 17 to 20, which is the highest group in MERV ratings. True HEPA filters have at least 99.97% efficiency in trapping 0.3-micron particles.
How often should you change a MERV 11 filter?
