  4. MPR Rating: The Key to Cleaner Air at Home

Tough on Microparticles

  • Close up of Filtrete filter media with text “Captures up to 2x more microparticles vs MERV alone*”
  • Meet your new partner in air quality.

    Filtrete™ Air Filters are the only air filters with both MERV (the industry standard) and MPR (specially engineered to measure microparticles) ratings. What does that actually mean? Our filters capture more particles than the industry standard without compromising airflow. You’ll get cleaner air without overworking your HVAC.

  • What is MPR?

    When it comes to air filtration, remember this one acronym: MPR (Microparticle Performance Rating). These three little letters zero in on those sneaky microparticles that could worsen your indoor air quality. Unlike MERV (Minimum Efficiency Reporting Value), which simply sets the baseline for performance, the MPR rating system goes above and beyond to measure the capture of microparticles as small as 0.3 microns.

How to Choose the Right MPR Rating

Every home has its quirks, and that’s especially true when it comes to air quality needs. Whether it’s allergens, pets or the local pollen forecast, we’re here to help you find the perfect Filtrete™ Air Filter that suits your lifestyle.

Filtrete™ Filters capture more microscopic particles than required by the MERV Standard.

Check out how MPR-rated Filtrete™ Filters outperform MERV standards.

Why Microparticle Capture Matters

Dust, pollen, bacteria, viruses and smoke particles—just because you can’t see them doesn’t mean they’re not there, wreaking havoc on your indoor air quality. Think of your air filter as the superhero in the fight against these invisible troublemakers. Filtrete™ Air Filters harness the power of 3M Science to effectively capture and remove these unwanted particles from your air. Every MPR level not only filters out larger pollutants (like pollen and pet dander), but each level up targets more and more microparticles that could affect your home’s air quality.

  • *Filtrete MPR 1000 - 1200 capture 2x more small particles than MERV 11 requirement. Microscopic particles are 0.3-1.0 in size.
