## Description

desertcart.com The Filtrete 1000 MPR Micro allergen reduction filter not only vastly improves the air quality in your home, 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, and bacteria. With each pass through the specially pleated filter, the air in your living space improves, making for a healthier home environment. This air-cleaning filter outperforms comparable non-electrostatic fiberglass and washable and reusable one-inch filters.Electrostatic Design Captures More ParticlesThe 3M Micro allergen reduction filter is made with both positively charged and negatively charged fibers that act like tiny magnets to attract air-polluting contaminants. Since particles in the air are either positively or negatively charged, they are attracted to and captured by the filter and kept out of your living space.Electrostatic filters, including the 3M Micro 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.Improves Indoor Air QualityWith indoor air a surprising two to five times more polluted than outdoor air, the 3M Micro allergen reduction filter can make a difference in maintaining a healthier home environment by cleaning air with each pass through the filter.The 3M Micro allergen reduction filter features a 1000 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, and bacteria.Improves EfficiencyThis allergen-reduction filter also keeps your heating and air conditioning equipment working efficiently by removing dirt and reducing strain on the motor.
