Filtrete 14x20x1 AC Furnace Air Filter for Asthma & Allergy Friendly

Your home should be your sanctuary, starting with the air you breathe. Filtrete Allergen, Bacteria & Virus Air Filters help capture unwanted particles from your household air, contributing to a cleaner, fresher home environment. By proactively capturing dust, bacteria, viruses and allergens, these high-performance filters help improve your home's air quality.

The Filtrete 1500 MPR Ultra allergen reduction filter not only vastly improves the air quality in your home, but it also keeps your air conditioning and heating systems running efficiently, saving on utilities and maintenance costs. The electrostatic filter attracts and captures airborne dust, pollen, dust-mite debris, lint, mold spores, pet dander, smoke, smog, bacteria, and particles that can carry viruses. With each pass through the specially pleated filter, the air in your living space improves, making for a healthier home environment. This high-performance filter outperforms comparable non-electrostatic fiberglass and washable and reusable one-inch filters.

Electrostatic filters, including the 3M Ultra allergen reduction filter, perform better than comparable non-electrostatic fiberglass and washable/reusable filters because they attract and capture the small, allergy-aggravating microparticles that non-electrostatic filters can't.

With indoor air a surprising two to five times more polluted than outdoor air, the 3M Ultra allergen reduction filter can make a difference in maintaining a healthier home environment by cleaning air with each pass through the filter. The 3M Ultra allergen reduction filter features a 1500 Microparticle Performance Rating (MPR), which means it is able to capture large and small particles from the air, including household dust, pollen, dust-mite debris, mold spores, pet dander, smoke, smog, bacteria, and other allergens. This high-performance filter meets American Lung Association of the Upper Midwest Health House Program's indoor air quality guidelines.

This high-performance allergen-reduction filter also keeps your heating and air conditioning equipment working efficiently by removing dirt and reducing strain on the motor. It is recommended that you change the filter every three months, but the effectiveness and life of the filter can vary and depend on the individual conditions in your home.

For nearly 25 years, Filtrete filters have delivered cleaner air to millions of homes, becoming a leader in residential air filtration. Developed by 3M engineers to help capture airborne allergens, the Filtrete filter media is electrostatically charged to act like tiny magnets to attract and capture microscopic particles from the air as it passes through the filter. Today, a dedicated technical team continues to develop innovative filtration solutions for around the home, including air cleaning filters, room air purifiers, and water filtration products.

The pack includes four 3M 1500 MPR Ultra allergen reduction filters. These 3-month pleated 1" Filtrete 14x20x1 MPR 1500 AC Furnace Air Filters are slightly different from the nominal size, with exact dimensions of 19.81 x 13.81 x 0.81. They are designed with exclusive Filtrete 3-in-1 technology to pull in and trap unwanted particles, allowing cleaner air to flow through. With a 1500 MPR and MERV 12 rating, as well as a 54% small particle capture rate, these filters help capture many microparticles from the air passing through. They are CERTIFIED asthma and allergy-friendly and help capture dust, lint, and other allergens in your household air. These versatile filters can be used for changing any air filter in your furnace, air conditioner/heating system, or HVAC system, and it is recommended to change them at least once every 90 days for optimal performance.
