WHAT are FPR Air Filter Ratings?
FPR stands for “Filter Performance Rating.”
Created by The Home Depot for brands only sold in Home Depot stores, including popular Honeywell filters. This rating system was established to provide a unified ranking system but lacks specific figures for comparison and simplicity.
The FPR rating system features a number scale from 4-10 and color code is used to rate the filter’s quality and ability to trap certain particles.
