3M Filtrete 20 x 30 x 1-Inch 700 MPR MERV 8 Dust Reduction Furnace Air Filter, 4-Pack - 4021892-4 Pack

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. For residential use only. 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.
