Captures particles such as dust, pollen, and pet dander. ASHRAE 52.2 defines the performance level that a filter must achieve to obtain a certain MERV rating. The goal of these tests is to give an accurate representation of an air filter’s performance at removing particles of different sizes. MERV vs MPR vs FPR . 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 … Designed by The Home Depot for brands sold through their stores, including Honeywell, this rating structure is very similar to MERV rating. HEPA filters are able to filter out 99.97% of the smallest E1 particle on the MERV scale. PM10 particles are typical particles in the E3 range. 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. The MERV filter rating is the domestic and international industry standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning There are twelve different size ranges of particles that are tested. 05.27.2020. HEPA filters are typically only used for the absolute most stringent environments– such as hospital operating rooms, clean rooms for computer chip manufacturing, etc. MPR - Microparticle Performance Rating. Hey, it’s going to be okay. However, at the end of the day, the ratings apply to the SAME filters! APR 450 Rating = MPR 300 = MERV 6 Efficiency: Clean air of lint, dust & pollen. Many HVAC companies and distributors offer filters with a MERV rating between one and 20. MPR measures ratings based on sizes 0.3 to 1 microns. We’ll make sense of these two systems and compare them to each other to show you what they measure, how they measure it, and what their differences are. Learn the differences between MERV, MPR & FPR to choose the best filter for your needs. None the less all of these rating systems were created to do the same thing... Rate Filters. Available in MERV 6, MERV 8, MERV 11, and MERV The diagram below shows a comparison between the sizes of E1, E2, and E3 particles. Learn more about proper air filter maintenance and associated benefits. Select from 1", 2', and 4" depths. HVAC Training Shop is reader-supported. E1, E2, and E3 are the three different size groups of particles that are tested with air filters. FilterBuy Bronze MERV 6 vs Filtrete MPR 300 Bronze is the entry-level filter from FilterBuy. The Minimum Efficiency Reporting Value, or MERV rating system is defined in ASHRAE standard 52.2. The published MPR Rating numbering system is a scale of 0 – 2700, with their highest published furnace filter equaling the Nordic Pure MERV 13. However, at the end of the day, the ratings apply to the SAME filters and can be used in your furnace or AC unit! With our custom air filter wizard, you can build a size to fit your needs. It rates the manufacturer’s filters and their ability to capture airborne particles smaller than 1 micron. To learn more about MERV ratings, click here. MPR is helpful when comparing one 3M Filtrete filter to another, but it does not directly translate to MERV. 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. FPR, MERV, MPR – it doesn't matter! When it comes to the average home, anything rated MERV 7 to 12 is sufficient to filter airborne contaminants. It is the industry-standard air filter rating system. When it comes to purchasing a new air filter , you may feel out of your depth when trying to understand the various acronyms that you’ll find within product listings. For comparison, MERV-16 filters are rated for only capturing >95% of E1 particles, which include particles between 0.3 and 1.0 microns. The testing factors for ASHRAE 52.2 were developed to provide filter efficiency data for different particle sizes. HEPA filters are tested and certified to filter out at least 99.97% of 0.3 micron particles. HVAC Training Shop is reader-supported. 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. MPR was created and is used by 3M while FPR is created and used by Home Depot. 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. As you have already learned, the MERV rating is the primary rating system used in the industry, both domestically and internationally. MPR FILTERS. In other words, popular brands are using their own rating systems to rate their filters. These particles can be inhaled and cause health concerns. The higher the rating, the smaller the particles the filter catches. Catch All*: MERV 13 - blocks particles = 0.3–1.0 μm (2200 MPR, FPR= 10/Black) * When we say "Catch All", we mean it collects all the particles you could worry about in an average household while still providing proper air flow. The higher the MPR rating the better the filters ability to capture particles from the air. Particulate matter that is less than 2.5 micrometers in diameter poses the greatest risk to your health. The MERV system is the only nationally regulated and independent filtration system. MERV ratings extend from 1 to 16. Take a breath and whatever you do, don’t read the newspaper. The E1, E2, and E3 particle groups are determined by ASHRAE standard 52.2. This rating describes how effectively the filters remove particles and … Each of these size ranges is put into one of three different groups: E1, E2, and E3. 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. of Energy). See our section below on the differences between E1, E2, and E3 particles. Check out our article for information on the differences between the MERV and MPR ratings. As the air flows through a test duct, it passes through the filter, and some of the particles become trapped in the filter. The air filter’s performance is determined by counting the particles before and after the filter. FilterBuy MERV 8 Pleated AC Furnace Filter. Even though they have completely different numbers, they are still air filters and can be compared directly against each other. Typical E2 particles are pet dander and some larger bacteria, such as E. coli. The MPR filter rating system is intended to measure a filter’s effectiveness for particles in the PM2.5 range. Also captures bacteria, smoke, and some viruses. The table below shows what percentage of particles must be trapped in order to obtain each MERV rating. MERV stands for minimum efficiency reporting value. The largest selection of AC and Furnace Filters, shipped directly to your home. MERV, or Minimum efficiency reporting value, is a measure developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE); MERV ratings range from 1-20.

This is not to say that MERV filters are poor quality in reality they are more than adequate for the needs of most homeowners. At 3M, we believe MERV only tells part of the story. FPR ratings are on a scale from 4 through 10. 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. 0.3 micron particles are the smallest particles that are tested by the MERV rating scale. Six tests are done on a single filter– the test is started with a clean filter, then that same filter is used for five additional tests. Captures particles such as dust, pollen, and pet dander. FPR, or filter performance rating, labels filters based on a number scale from 4 through 10 in addition to a color-coding system. 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. Dust Mites, Mold Spores, Lint, Household Dust, & Pollen, Pet Dander, Smoke, Smog, Coughing, Sneezing Dust Mites, Mold Spores, Lint, Household Dust, & Pollen, Bacteria, Virus Carriers, Pet Dander, Smoke, Smog, Dust Mites, Mold Spores, Lint, Household Dust, & Pollen.
