The MPR indicates the filters ability to capture tiny particles between 0.3 and 1 micron in size. MPR, or Micro-Particle Performance Rating, pertains only to products developed by the 3M company; typical MPR ratings range from 300 to 2200. FPR, MERV, MPR – it doesn't matter! APR 650 Rating = MRP 600 = MERV 8 Efficiency: Clean air of dust mites & mold spores. Captures particles such as dust, pollen, and pet dander. In this article, we’ll take a look at the differences between two of the most common air filter rating systems– MERV and MPR. For instance, a filter with a rating of MPR 2200 is able to remove 69% of E1 particles– particles in the 0.3 to 1.0 micron range. The MPR rating system is measured on a scale from MPR 300 to MPR 2800. MERV vs. MPR vs. FPR: What Air Filter Rating Should I Choose Air filters are a key component in any air conditioning system. These are the smallest particles that are measured on the MERV and MPR scales. Particles smaller than 0.3 microns are not measured on either of these scales. Just be sure to remember that the higher the MERV rating, the better the filtration. Filtrete said MPR 1900 is equivalent to MERV 13, MPR 1500 to MERV 12, and MPR 1000 to MERV 11. The diagram below shows a comparison between the sizes of E1, E2, and E3 particles. When it comes to the average home, anything rated MERV 7 to 12 is sufficient to filter airborne contaminants. The higher the MERV rating, the higher the effectiveness of the air filter Microparticle Performance Rating, or MPR for short, is a filter rating system developed by 3M to rate a filters ability to cature the smallest airborne particles. Same quality, same filter, half the price of retail store brands. This Website requires your browser to be JavaScript enabled.Please enable JavaScript and reload this page. MERV isn’t the only performance rating that you might run into when shopping for a furnace filter. Basically, the more particles that were trapped in the filter, the higher the filter’s efficiency. The size of these particles is typical of dust, pollen, and mold spores. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. E1 particles are representative of extremely small particles such as smoke, haze, bacteria, and some viruses. In other words, popular brands are using their own rating systems to rate their filters. PM2.5 particles consist of mostly E2 and E1 particles. Here’s how MPR stacks up with the MERV rating. Since particles in this range are the cause of health problems, filtering them out will improve the air quality inside your home and help prevent health issues that stem from microparticles. FPR - Filter Performance Rating The MPR rating system was created by 3M to measure an air filter’s effectiveness at filtering out microparticles. Any filter rated on the MERV scaleis rated based on its ability to capture medium to large particles that range from 1 to 10 microns, as well as its ability to capture submicron particles that range from 0.3 to 1.0 micron. It rates the manufacturer’s filters and their ability to capture airborne particles smaller than 1 micron. The MPR-2800 would qualify as a MERV-14, so even though 3M emphasizes the smallest size range of particles, their best filter doesn’t qualify for the highest MERV … Available in MERV 6, MERV 8, MERV 11, and MERV The E1, E2, and E3 particle groups are determined by ASHRAE standard 52.2. When you want the best possible air filter for your home, microparticles matter most — they make up 99% of the particles that are in the air. 3M filters focus strictly on the latter—the submicron particles, and they use a rating system called MPR. For instance, a MERV-13 filter is very similar to an MPR 1500 filter in terms of how effective they are at capturing particles of E1, E2, and E3 sizes. FilterBuy Bronze MERV 6 vs Filtrete MPR 300 Bronze is the entry-level filter from FilterBuy. The MPR filter rating system is intended to measure a filter’s effectiveness for particles in the PM2.5 range. MERV: Minimum Efficiency Reporting Value developed by the American society of heating,refrigerating and Air Conditions Engineers. PM10 particles are typical particles in the E3 range. See our section below on the differences between E1, E2, and E3 particles. The higher the MPR rating the better the filters ability to capture particles from the air. At Air Filters Delivered, we label our air filters by their MERV filter rating. Also shown is the cross-sectional diameter of a human hair, which is much larger than any of those particles. E1, E2, and E3 are the three different size groups of particles that are tested with air filters. For instance, in order for a filter to obtain a MERV-13 rating, the filter must be able to capture at least 50% of E1 particles, 85% of E2 particles, and 90% of E3 particles. The MERV rating system is the industry-standard rating system. This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). APR 1550 Rating = MPR 1000 to 1200 Rating = MERV 11 Efficiency: Clean air of pet dander, smog and smoke As an Amazon Associate, we earn from qualifying purchases. This rating is exclusive to filters that are manufactured and sold by the home improvement brand 3M in partnership with Filtrete. You may choose from four different options: To better understand what sets the four ratings apart, take a look at our MERV rating chart! The higher the MPR, the more microparticles — such as pollen, pet … The MPR, or Microparticle Performance Rating system is designed to measure an air filter’s filtration of microparticles. Home Depot shared a basic comparative chart but no test data or protocols; it … MERV 6 = ~MPR 300; MERV 8 = ~MPR 600; MERV 11 = ~MPR 1000-1200; MERV 13+ = ~MPR 1500-1900+ The Filter Performance Rating, developed by Home Depot for brands sold through their store including Honeywell and Holmes brands. Different companies have different rating systems. Minimum Efficiency Reporting Value, or MERV for short, is a filter rating system devised by ASHRAE, the American Society of Heating, Refrigeration and Air Conditioning Engineers, to standardize and simplify air filter efficiency ratings for the public. The MPR rating system is an air filter rating system created by 3M. These particles can be inhaled and cause health concerns. MERV 8 pleated air filters attract and trap large airborne particles such as lint, dust, pollen, bacteria, pet dander, dust mites, mold spores and other contaminants. FPR, or filter performance rating, labels filters based on a number scale from 4 through 10 in addition to a color-coding system. FPR ratings are on a scale from 4 through 10. The higher the rating, the smaller the particles the filter catches. Many HVAC companies and distributors offer filters with a MERV rating between one and 20. Specifically, the system focuses on measuring a filter’s efficacy for particles in the 0.3 to 1.0 micron range. HEPA filters are tested and certified to filter out at least 99.97% of 0.3 micron particles. ASHRAE 52.2 defines the performance level that a filter must achieve to obtain a certain MERV rating. 4-pack of MERV-13 filters. Check out our article for information on the differences between the MERV and MPR ratings. MPR (Microparticle Rating) is a rating system that includes microscopic particles not visible to the naked eye. If you have been shopping for air filters, you’ll notice that there are a few different rating systems out there. Engineers. The table below shows what percentage of particles must be trapped in order to obtain each MERV rating. It is the industry-standard air filter rating system. With our custom air filter wizard, you can build a size to fit your needs. The ability to capture a lot of th… The higher the MPR, the more microparticles—such as pollen, pet dander, smoke, bacteria and viruses—your filter will capture from the air passing through it. Also captures bacteria, smoke, and some viruses. For reference, a typical dust particle is between .2 and 8 microns, while pollen starts at 7 microns and can get up to 70 microns in size.
