Shop by Filter Ratings

The FPR Rating is a grading system for filters based on a scale from a good quality 4 rating (green) to a premium rating of 10 (black). Air filters remove airborne contaminants ensuring you healthier air. The higher the rating, the fewer unwanted particles will pass through the filter.

The Home Depot has developed an Air Filter Performance Rating System on a scale of 4 (good) to 10 (premium) to help you select the type of filter that best suits your home's filtration needs.
