High-efficiency particulate air (HEPA) filters are proven to be the most trusted filter technology on the market. HEPA is a flat, pleated sheet composed of millions of microscopic fiberglass threads, forming a complex maze which traps airborne particles. It is the most advanced filter technology on the market and removes 99.97 percent of particles as small as 0.3 microns.
