Filtrete 20 in. W X 20 in. H X 1 in. D 6 MERV Pleated Air Filter 1 pk

You run a tight ship at home, from floor to ceiling - any 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 Pollen 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.
