The Dust-Reduction Filter helps you maintain a healthier home environment. View larger.

Electrostatic filters like the 3M Dust-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 Dust-Reduction Filter can make a difference in maintaining a healthier home environment by cleaning air with each pass through the filter.

Ideal for capturing large particles from the air, including household dust and pollen, the 3M Dust-Reduction Filter features a 300 Microparticle Performance Rating (MPR).

Improves Efficiency
This dust-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.
