3M Filtrete 1000 MPR 14 x 25 x 1 Inch Allergen Defense Air Filter 4 Pack

Outperforms fiberglass, washable and non-electrostatic 3-month pleated 1 in. home air filters for your furnace, air conditioner or HVAC system

Designed with exclusive filtrete™ brand 3-in-1 technology from 3m to trap unwanted air particles while letting cleaner air flow through

Attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog

1000 MPR has a rating of MERV 11

The higher the mpr, the more microparticles–such as pollen, pet dander, smoke, bacteria and viruses–your filter will capture from the air passing through it

For optimal performance of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1 in. filters, and at least every 12 months for 4 in. and 5 in. filters

A dirty filter will slow down air flow and make the system work harder to keep you warm or cool–wasting energy

For residential use only
