HEPA Filters for Improving Indoor Air Quality
HEPA Filters FAQ
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).
What is a HEPA air purifier?
HEPA stands for High Efficiency Particulate Air. A HEPA air filter is made up of thousands of extremely fine fibres arranged into a matt to intercept both microscopic particles and larger ones. An air purifier will push air from the room through the filter to remove pollutant particles.
What is a high efficiency HEPA filter?
High-efficiency particulate air. High-efficiency particulate absorbing. High-efficiency particulate arrestance. In theory, a HEPA filter is literally any filter that can capture at least 99.97% of very small 0.3 microns in size particles.
How does a HEPA air filter work?
A HEPA air filter is made up of thousands of extremely fine fibres arranged into a matt to intercept both microscopic particles and larger ones. An air purifier will push air from the room through the filter to remove pollutant particles. By definition HEPA filters can trap close to 100% of the particles in the air that are 0.3 microns or smaller.
Do HEPA filters work?
