Filtrete 705-4 Air Filter, 20 in L, 14 in W, 8 MERV, 700 MPR, Fiberglass Frame

You run a tight ship at home, from floor to ceiling -- so opt for a Filtrete™ Air Filter. Bad news is that ordinary home non-electrostatic air filters aren't super effective at capturing unwanted particles. GOOD NEWS is: 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.

• ATTRACTS AND CAPTURES particles such as lint, pollen, dust, and pet dander.
• OUTPERFORMS FIBERGLASS, WASHABLE AND NON-ELECTROSTATIC 3-month pleated 1 in. air filters for your furnace, air conditioner or HVAC system
• DESIGNED WITH EXCLUSIVE Filtrete™ Brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner air flow through.
• FOR OPTIMAL PERFORMANCE of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1 in. filters and 12 months for 4 - 5 in filters.
• MPR 700 has a rating of MERV 8
• The higher the MPR, the more microparticles - such as pollen, pet dander and smoke - your filter will capture from the air passing through it
