3M Filtrete 10 In. x 20 In. x 1 In. Basic Dust & Lint 300 MPR Furnace Filter

You run a tight ship at home, from floor to ceiling -- and everywhere in between. Unfortunately, ordinary home non-electrostatic air filters arent super effective at capturing unwanted particles. GOOD NEWS: The unique design of the electrostatically charged Filtrete Basic Dust Air Filter attracts -- and trap --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:

• 3-month pleated 1 in. air filters for your furnace, air conditioner or HVAC system
• 3-in-1 technology traps unwanted air particles while letting cleaner air flow through
• Attracts & captures large particles such as lint, household dust and dust mite debris
• Outperforms fiberglass, washable, and non-electrostatic filters
• MPR 300 has a rating of MERV 5
• The higher the MPR, the more microparticles - such as pollen, pet dander and smoke - your filter will capture from the air passing through it
• Change filter at least every 90 days for optimal performance of your heating & cooling system or HVAC system
• A dirty filter will slow down air flow and make the system work harder to keep you warm or cool - wasting
• For residential use only
