Filtrete™ 20 x 20 x 1 Air Filter, 12 HVAC Filters, MPR 700, MERV 8, Optimized HVAC Airflow, Dust, Pollen & Pet Dander, 3 Month AC and Furnace Filters

The Filtrete™ Dust, Pollen, and Pet Dander outperforms non-electrostatic pleated and washable filters. This filter helps capture particles including lint, pollen, dust and pet dander. You run a tight ship at home, from floor to ceiling--and everywhere in between. Unfortunately, ordinary home non-electrostatic air filters aren’t super effective at capturing unwanted particles. GOOD NEWS : The unique design of the electrostatically charged Filtrete™ Dust, Pollen & Pet Dander Air Filter attracts--and traps--more particles from your air through your heating and cooling system, making quality control a breeze. With each cycle through the filter, your indoor air becomes a little bit cleaner.
