What is the difference between true HEPA and HEPA 13?

The best HEPA air purifiers will use H12 HEPA filters. However, H13 is even better than normal HEPA filters. Specifically, the H13 filter captures particles that are more than 3x smaller than classic HEPA filters. … “H13 HEPA filters remove at least 99.9% of airborne particles 0.1 micrometers (μm) in diameter.”

Is True HEPA the same as HEPA 13?

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 HEPA 13 air purifier?

H13-H14 HEPA are within the highest tier of HEPA air filtration and are considered medical-grade. “A HEPA grade of H13 can remove 99.95% of all particles in the air measuring 0.2 microns in diameter, while a HEPA grade H14 removes 99.995%,” says Nagl.

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.

Whats better MERV 13 or HEPA?

HEPA filters are at the highest MERV level and do the best with protecting against air pollutants. … 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).

Does HEPA 13 filter Covid?

Is True HEPA real?

Although the standard for HEPA filters is that they need to be able to filter out 99.95% or more of all particles which are 0.3 microns in diameter, they are actually capable of filtering out particles of almost any size. A True HEPA filter can trap dust, smoke, pet allergens, PM2.

Can a HEPA filter help with Covid?

When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19.

Does MERV 13 filter out viruses?
