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.
