What is a HEPA Filter?
A HEPA filter is a high efficiency air particulate air filter that can capture
ultrafine pollutants. HEPA filters are considered the industry standard for removing
dust, pollen, mold, bacteria, particulate matter, and other airborne particles. A
HEPA filter is found in air purifiers and forced-air HVAC systems. There are two
common standards for HEPA filters: European and U.S. In Europe, HEPA filters must
remove 99.95% (ISO) of particles that are 0.3 microns in size. In the U.S., HEPA
filters must remove 99.97% of particles that are 0.3 microns in size.
