What is a HEPA Filter and How Does It Work?
What is a HEPA Filter?HEPA stands for high efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. You can find HEPA filters in most air purifiers and in almost every cleanroom.Why are HEPA Filters Important?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. Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes).This means that you can guarantee a clean and repeatable process, each and every time.HEPA Filters for CleanroomsIn almost every cleanroom, HEPA filters are a necessity. HEPA filters are often mounted in … Continued
