Is MERV 13 the same as HEPA?

While a MERV 16 filter captures >95% of particles in the entire size range tested (0.3-10.0 microns), a HEPA filter captures 99.97% of particles with a size of 0.3 microns. The filtering efficiency is even higher for particles larger or smaller than 0.3 microns.

Do HEPA filters have MERV ratings?

HEPA Filters HEPA air filters are not MERV rated as they exceed the ASHRAE test protocol 52.2 used in determining the MERV ratings. In fact, HEPA air filters are the ONLY mechanical air filters that are tested and certified to meet a specific efficiency at a specific particle size.

Is MERV 15 a HEPA filter?

HEPA stands for High Efficiency Particulate Air filters and they are super-efficient. They will range from 17-20 MERV. HEPA filters meet standards that remove at least 99.97% of airborne particles down to the size of 0.3 microns.

Is MERV 13 too high?

How efficient is a HEPA filter?

HEPA filters have a minimum particle collective efficiency of 99.97% for particles of 0.3 µm diameter or more. A HEPA filter typically lasts three to five years, depending on hours of operation, cleanliness of the laboratory, and type of work being performed.
