What is the difference between a HEPA filter and a true HEPA filter?

The main differences between HEPA-type and True HEPA filter are the filtration efficiency. In general, HEPA-type filter has a 99\% efficiency rate of capturing particles as small as 2 microns. True HEPA filter up the game with a better 99.97\% efficiency rate at particles as small as 0.3 microns.

What Merv is a true HEPA filter?

MERV 17
All HEPA filters have a rating of a MERV 17 or higher. A HEPA filter with a MERV 17 rating will trap 99.97\% of air particles that are 0.3-1.0 micron in size and an even better \% of particles below 0.3 microns and above (HEPA filters are rated at their worst performance).

Is HEPA 13 True HEPA?

True HEPA generally ranges from H10-H12. This is the “grade” of HEPA or the level of efficiency. The higher the grade, the better the filter. Whereas H10-H12 filters only trap 85-99.5\% of all particles that are 0.1 microns in diameter, HEPA H13 and H14 trap 99.95\% and 99.995\% of such particles, respectively.

What is an ultra HEPA filter?

ULPA filters trap more and smaller particulate matter than HEPA filters. ULPA filters are 99.999\% effective at removing submicron particulate matter of 0.12-micron diameter or larger, while HEPA filters are 99.97\% effective for eliminating particulate matter of 0.3-micron diameter or larger.

Is MERV 13 bad for HVAC?

Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.

Is MERV 13 too restrictive?

MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.

What is H13 true HEPA?

A True HEPA filter often ranges between H10 and H12 which traps 85-99.5\% of particles that are 0.1 microns or larger. An H13 HEPA filter is designed to capture 99.95\% of pollutants of that size. This basically means that there is only a tiny percentage of extremely small contaminants will get through.

    What is true HEPA?

    HEPA is an acronym that stands for High Efficiency Particulate Air. This is a pleated filter that traps airborne particles as they pass through an air purifier. A true HEPA filter removes 99.97\% of all particles that are 0.3 microns in size or larger. This is known as the HEPA standard.

    What is a HEPA filter?

    HEPA is a type of pleated mechanical air filter. It is an acronym for “high efficiency particulate air [filter]” (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97\% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).
