How Do High Efficiency Air Cleaners Work?

High efficiency air cleaners incorporate a filtering media made from microscopic fibers woven into an intricate web that traps and holds airborne particles of dust, pollen, animal dander, etc. The spaces between the fibers are so small that particles as tiny as 0.01 micron are easily captured. By comparison, a particle 300 microns in diameter (30,000 times larger) would fit easily through the eye of a sewing needle!
