20x20x1 700 Mpr Filter

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.

Features:

• The higher the MPR, the more microparticles your filter will capture from the air passing through it
• For optimal performance of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1 inch filters, and at least every 12 months for 4 inch and 5 inch filters
• Attracts and captures particles such as lint, pollen, dust, and pet dander
• A dirty filter will slow down air flow and make the system work harder to keep you warm or cool--wasting energy. Sign-up for a filter change reminder program
• Designed with exclusiveFiltrete Brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner air flow through
• Attracts and captures microscopic particles
• MPR 700 has a rating of MERV 8
