About MERV, MPR and FPR Rating
The three rating systems were created by different organizations. MERV is the domestic and international Industry Standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. The other two rating systems were created by 3M and The Home Depot, but all are rating the same filter.
MERV Rating (Minimum Efficiency Reporting Value): As you have already learned, the 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 (Micro-Particle Performance Rating): 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 (Filter Performance Rating): 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.
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.

Review topics: [size, fit, delivery, service, quality, price, use, filters, order].
"I really can't review the product at this time since I only had the filter installed for a few weeks. But I can review how easy it was to order and receive 6 filters. Price for 6 was comparable to other sellers, Factory direct had FREE shipping which is a perk for me. Arrived in 5 days, good packing. Will re-order in 6-7 months if they still offer FREE shipping."
"Great price and everything delivered as promised"
"Fit to size well made easy install"
"Foun"
"Always pleased with my filters from Factory Direct. I buy a box of them and label them by month. At a glance I know whether I changed the filter or not by looking at the box of remaining filters."
"The first shipment arrived damaged. They re-shipped quickly. Good customer service."
"A quality product and a company with excellent service. Factory Direct sent the wrong filters for my last order but immediately corrected the issue by sending the correct order. I like that they covered the mistake promptly and did not ask me to return the others. I was able to benefit someone else from their mistake."
"It’s always easy and quick dealing with Factory Direct for purchasing my filters. Thank you!"
"I tried to get my filters from somewhere else, however after a few years my "buy again" messed up and they sent the wrong size which I didn't notice right away. I feel more confident now and know I can rely on getting things on time."
"These fit my carrier air conditioner. They’re hard for me to find because carrier made them an odd size. I changed them once a month when the electric bill comes in so I don’t forget and I’m good to go. ."
