54% Small particule capture, like bacteria and particles that carry viruses ( % captured is based on ASHRAE 52.2 testing for 0.3 to 1 micron particles from the air passing through the filter, which relates to HVAC … of Energy). HVAC Training Shop is reader-supported. Go to Comment. Allergen Defense Filters, including Filtrete™ Allergen Reduction + 2x Dust Defense Filters, are capable of capturing even more particles. To test a filter, an aerosol generator is used to spray particles of known sizes into an air stream. It is also an excellent choice for homeowners who live in metropolitan areas with a lot of air pollution and smog. ASHRAE 52.2 defines the performance level that a filter must achieve to obtain a certain MERV rating. See our section below on the differences between E1, E2, and E3 particles. PM2.5 particles consist of mostly E2 and E1 particles. Learn more about proper air filter maintenance and associated benefits. 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 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. Here’s a simple way to remember what FPR numbers mean: … The other two systems were created by "3M" (MPR) and "The Home Depot" (FPR) to differentiate their offerings. Allergen Defense Filters, including Filtrete™ Allergen Reduction + 2x Dust Defense Filters, are capable of capturing even more particles. MPR 1500 (equal to MERV 11) These HVAC air filters remove up to 90 percent of all indoor air particles between 3 and 10 microns. Side by Side Comparisons . Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings. Filtrete 1500 MPR (Microparticle Performance Rating) equates to MERV 12; 1550 MPR available in 4”, 4” slim fit and 5” air filters; For maximum performance, change your home air filter at least every 90 days for 1” filters, and at least every 12 months for 4” and 5” filters. Because the filter is thin and the MERV is high, it reduces airflow into the duct system. Need a hard-to-find or extended size? The three rating systems were created by separate organizations. For example, let's say you have a pleated filter that's 1-inch thick and has a 13 MERV rating. 1500 MPR has a rating of MERV 12 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 APR 650 Rating = MRP 600 = MERV 8 Efficiency: Clean air of dust mites & mold spores. MPR 1900 (equal to MERV 12) These HVAC air filters remove up to 93 percent of all airborne particles between 3 and 10 microns. 1500 MPR has a rating of MERV 12; 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; 54% SMALL PARTICLE CAPTURE, like bacteria and particles that carry viruses* (* % captured is based on ASHRAE 52.2 testing for 0.3 to 1 micron particles from the air passing through the filter, which relates to HVAC … The air filter industry standard rating for filter efficiency … MPR 1500 filters take everything a step further and are able to filter out some bacteria and viruses. At Air Filters Delivered, we label our air filters by their MERV filter rating. In this article, we’ll take a look at the differences between two of the most common air filter rating systems– MERV and MPR. 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. Created by 3M, only filters designed by the 3M/Filtrete brand carry an MPR rating, which rates the filter’s ability to trap air particles smaller than 1 micron. APR 1550 Rating = MPR 1000 to 1200 Rating = MERV 11 Efficiency: Clean air of pet dander, smog and smoke. For MERV 14, 15 and 16 are rated to stop 75%, 85% and 95%, respectively. 1500 MPR has a rating of MERV 12 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 54% SMALL PARTICLE CAPTURE, like bacteria and particles that carry viruses ( % captured is based on ASHRAE 52.2 testing for 0.3 to 1 micron particles from the air passing through the filter, which relates to HVAC … MERV 6 = ~MPR 300; MERV 8 = ~MPR 600; MERV 11 = ~MPR 1000-1200; MERV 13+ = ~MPR 1500-1900+ FPR: The Filter Performance Rating, developed by Home Depot for brands sold through their store including Honeywell and Holmes. The particle removal rate of air filters is tested using these three different size groups to determine their efficiency. Some of them are even able to get into your bloodstream. 1500 MPR Smart Allergen, Bacteria & Virus Air Filter ... • MERV 12 rating. The pressure drop was THE SAME. The air filter’s performance is determined by counting the particles before and after the filter. MPR measures ratings based on sizes 0.3 to 1 microns. Basically, the more particles that were trapped in the filter, the higher the filter’s efficiency. MPR 1500 filters take everything a step further and are able to filter out some bacteria and viruses. differences between E1, E2, and E3 particles. MPR 1500 HVAC air filters capture both larger and smaller allergens, and even particles that carry odors and viruses. FPR, MERV, MPR – it doesn't matter! None of them are rated for performance in the sub-micron size range where the Covid-19 … 13 ratings. 3M Filtrete filters (MPR 600 or higher), when clean and new, outperform all other fiberglass, washable and non-electrostatic 1" residential air filters. Here’s how MPR stacks up with the MERV rating. HEPA is a type of pleated mechanical air filter. MERV 6 = ~MPR 300; MERV 8 = ~MPR 600; MERV 11 = ~MPR 1000-1200; MERV 13+ = ~MPR 1500-1900+ Established by the ASHRAE … 3-10 microns 97% MERV 12 pressure drop .12 Ultra Allergen 1500 310 … MPR 1500 vs MERV 12 06 MPR 1900 vs MERV 13 07 MPR 2200 vs MERV 13 08 MPR 2500 vs MERV 14 09 MPR 2800 vs MERV 14 10 Reasonable capture rate based on Minimum E˜ciency Capture. Above, Pleat Spacing on Filtrete® Advanced Allergen Reduction Filter A truly incredible feat. rolfeskj. To learn more about MERV ratings, click here. While MERV ratings reflect a filter's ability to trap both microscopic and macroscopic particles, MPR ratings only grade a filter on its capacity to remove particles from 0.3 to 1 microns. Filter Depth/Thickness: 1 in. This is not very useful if you are trying to compare to other Brands of filters. HEPA filters are a different beast altogether. MERV 13 or MPR 1500: Helps prevent the spread of viruses & bacteria; MERV 14-16 or MPR 1900-2800: Typically for hospital use; requires a powerful HVAC system; Now, I’d avoid 3M’s “Basic Pleated” MPR 100 filter. ASHRAE standard 52.2 also defines the methods for testing filter efficiency by particle size. We have your filter! The Minimum Efficiency Reporting Value, or MERV rating system is defined in ASHRAE standard 52.2.
