HEPA Air filters remove tiny particles from dust, mold, pollen, bacteria, viruses, and more from the air. Thin glass fibers are randomly arranged into a dense, paperlike material that is folded into pleats to create the filter.
As air particles pass through these filters, pollutants are trapped in the fibers. Then, as larger particles stick to the filter, they keep other smaller particles from passing through. A HEPA filter can trap particles as small as 0.1 microns. For reference, the smallest thing the human eye can see is 25 microns, and a strand of hair is between 17 and 180 microns in diameter.
When placed into filtration systems like air cleaners and purifiers, HEPA filters can remove 99.97 percent of particles from the air. These filters were initially used in nuclear plants, but a host of new devices use this technology in products that can help clean the air in your home.
Air purifiers help trap dust before it has the chance to settle, reducing build up and leaving your workplace or home cleaner.
Air purifiers remove up to 99% of airborne bacteria. Small airborne particles like pollen, mold spores, viruses and other bacteria float around in the air, the air purifier effectively removes these particles. They do this by cycling the air in the room repeatedly through internal filters capturing particles as small as 0.1 microns.
