Did you know that 40 million Americans have allergies? To help improve indoor air quality in your home, upgrade to a high performance air filter like 3M’s Filtrete Elite Allergen Reduction Filter . It captures 94% of large airborne particles such as pet dander, mold  spores and dust mite  debris. It also traps up to 40 times more microscopic particles than ordinary fiberglass filters, so your family breathes cleaner air. The U.S. Environmental Protection Agency recommends changing your air filter every three months, but changing your filter more often may also help your heating and cooling system run more efficiently, helping it last longer.
