What Is Mpr Filter Rating

There are lots of acronyms out there to draw filter ratings, and they tin can all be a little confusing. MERV…MPR…FPR. What do they all mean, and how practise they differ from each other? Basically, they are all ratings systems for the filters you apply in your furnaces every day.

Ane refers to the domestic and international Industry Standard rating organization established past the American Society of Heating, Refrigerating, and Air Conditioning Engineers, while the others were created past 3M and The Home Depot. Let's go over each of them.

MERV Rating (Minimum Efficiency Reporting Value): This is the preferred, primary rating system used in the furnace filter industry established by the American Gild of Heating, Refrigerating, and Air Conditioning Engineers. Essentially, MERV reflects a item filter's ability to capture and hold particles and pollutants such as pollen, dust mites, mold spores, tobacco smoke, smog, dust and pet dander. They range from one to 16, with the lower and heart ranges designed for common residential and commercial use, and the high ranges designed for clean room and hospital employ. When it comes to the boilerplate habitation, anything rated MERV vii to 12 is sufficient to filter airborne contaminants.

MPR (Micro-Particle Performance Rating): This rating system was developed by the company 3M, designed to rate the manufacturer's filters and their power to capture airborne particles smaller than 1 micron. This system helps customers compare Filtrete filters based on the level of air filtration desired. The college the MPR, the better the filter's ability to capture particles from the air, simply taking into account microscopic particles between 0.iii and i microns.

FPR (Filter Performance Rating): This rating organisation was created by The Home Depot pertaining to brands sold in their stores, including Honeywell. A color lawmaking and number scale (4 to ten) closely resembling the MERV rating characterizes the FPR. The Abode Depot stopped using MERV ratings a few years agone and now exclusively relies on its own system, which accounts for the ability to capture big and small particles, too as measure weight gain over the filter's lifetime.

While all of the above systems accept unlike numbers to represent the power of capturing particles, they are all substantially saying the aforementioned thing. That existence said, MERV is the merely nationally regulated, independent rating arrangement for air filters. Why are there iii dissever ratings systems for substantially the same filters? Most likely simply a marketing ploy by these companies to promote their own brands, but that'south just a all-time guess. The fact remains that nosotros rely on MERV ratings here at Filtration Montreal.
