MERV or Minimum Efficiency Reporting Value is the industry-standard reporting value for air filters. AC filter MERV ratings start at 1 and go up to 16. At FiltersFast.com, our branded air filters are categorized by MERV ratings. We sell the most recommended MERVs for residential application: MERV 8, MERV 11 and MERV 13.

MPR or Microparticle Performance Ratings were developed by 3M which is the company that makes Filtrete Air Filters. MPR Ratings range from 100-2800 and indicate the filter’s capacity to remove particles from 0.3-1 micron. We do carry 3M Filtrete Filters on our site, so we’ve done some research to see what MERV ratings a few MPR ratings have:

  • 800 MPR, 1000 MPR, 1085 MPR & 1200 MPR have a rating of MERV 11
  • 1500 MPR & 1550 MPR have a rating of MERV 12
  • 1900 MPR & 2200 MPR have a rating of MERV 13
  • 2800 MPR has a rating of MERV 14

FPR or Filter Performance Ratings were created by The Home Depot. Ratings go from 4 to 10 and are very similar to MERV ratings. Here’s a simple way to remember what FPR numbers mean: the higher the number the better the air filter performance is according to The Home Depot.
