HEPA stands for high-efficiency particulate air [filter], and it is a form of mechanical filter. Theoretically, HEPA filters can remove bacteria, dust, pollen, and airborne particles of size as small as 0.3 microns with 99.97 percent efficiency.
While purchasing an air purifier, it is suggested to check for the authenticity of the HEPA filters. HEPA-13 and HEPA-14 are medical-grade filters. They are the highest tier of HEPA air filtration.
The difference between the two is that H13 can remove 99.95% of particles up to 0.2 microns, whereas H14 filters up to 99.995%. If you are unsure which one is best for you, get in touch with us today.
