MERV ratings let you know the efficiency and level of filtration that an air filter can handle under normal circumstances. The higher the MERV rating, the finer the particles are that are filtered our of the air in your home. Many air filter retailers use MERV or a similar rating to rate their air filters.
MERV Rating is the primary rating system used in the industry, both domestically and internationally. Established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, MERV rates a filter’s ability to capture and hold particles and pollutants.
MPR Rating is a rating system developed by 3M. It rates the manufacturer’s Filtrete product line and their ability to capture airborne particles smaller than 1 micron.
FPR Rating is a rating system developed by The Home Depot for brands sold through their stores, including Honeywell. It utilizes a color code and number scale (4 to 10) that closely resembles the MERV rating.

"Through no fault of Factory Direct, I got the wrong size filters. However FD made it easy to return my filters and purchase the correct size. The new filters arrived promptly and fit fine."

"I have bought these filters for years from Factory Direct, they are excellent, and their service is great, but, this is three times now that the box has come pushed down in shipment, with the filters kind of smushed inside. I would recommend factory direct to tell shippers not to load heavy boxes on top of their shipments. Thanks"
