Features: Filtrete 800 MPR Micro Particle Allergen Reduction Air and Furnace Filters not only vastly improve the air quality in your home, they also keep your air conditioning and heating systems running efficiently, saving on utilities and maintenance costs. The The 3M Micro Particle Allergen Reduction Filter is made with both positively charged and negatively charged fibers that act like tiny magnets to attract air-polluting contaminants. Since particles in the air are either positively or negatively charged, they are attracted to and captured by the filter and kept out of your living space. Electrostatic filters perform better than comparable non-electrostatic fiberglass and washable/reusable filters, because they attract and capture the small, allergy-aggravating microparticles that non-electrostatic filters can't. Indoor air quality is a surprising two to five times more polluted than outdoor air. The 3M Micro Particle Allergen Reduction Filter cleans air with each pass through the filter.
