Opt for a Filtrete Allergen Defense Air Filter to transform your central heating and cooling system into a whole-home air filtration operation. This no-nonsense filter helps capture varying sizes of particles, from the large (lint, pollen, dust and pet dander) to the microscopic (smoke and smog).
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.

This used Micro 1000 allergen reduction filter shows how much dust it collected from the air ().
By removing dust from the air, the filter also reduces strain on your furnace and air conditioner, helping to keep them running efficiently ().Electrostatic Design Captures More Particles
The 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 Quality
With 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 Efficiency
This 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. However, the effectiveness and life of the filter can vary and depend on the individual conditions in your home.
