What is a 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.

About MERV, MPR and FPR Rating

MERV Rating (Minimum Efficiency Reporting Value):

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.

Overall rating: 4.931818 / 5 from 44 reviews.

Reviews

Annual Filter Purchase

"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."

— Charles R. (5/5)

The first shipment arrived damaged.

"The first shipment arrived damaged. They re-shipped quickly. Good customer service."

— William F. (5/5)

Good quality product

"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."

— Mark W. (5/5)

Quick and easy

"It’s always easy and quick dealing with Factory Direct for purchasing my filters. Thank you!"

— Elaine A. (5/5)

Best service

"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."

— Victoria L. (5/5)

Works good

"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. ."

— Donna D. (5/5)

"Product as expected. Thanks"

"Tight size, fast delivery"

— James (5/5)

Rigid Activated? Carbon

"I have always thought of activated carbon as being composed of loose grains of carbon almost like sand so that the air could be in contact with all of the carbon. I wonder whether the more rigid, compact carbon in your filters will be as effective since most of the carbon is not in contact with the airflow. I would be interested in reciving a reply/answer."

— Julius H. (4/5)
