Filtrete 720-4 Air Filter, 24 in L, 12 in W, 8 MERV, 700 MPR (Pack of 4)

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 and 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. Online purchases are in packages of 4.
