What is the MERV & MPR rating of these filters?
Jana B. asked on Dec 13, 2013
The MERV is 11. The MERV (minimum efficiency rating) is the industry standard for rating air filters and MPR is not recognized by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) as that is a 3M Filtrete rating system. FPR rating of 6 is the Home Depot proprietary rating system and these filters were certified that way also.
