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.

• Electrostatically charged fibers attracts and capture large airborne allergens like: Pollen, Household Dust, Lint
• Ideal for high-velocity heating and cooling systems
• 300 MPR Performance Rating
• Lasts up to 3 months
• 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 energy. Sign-up for a filter change reminder program that works for you!
