For this blog, we will be referring to the MERV (Minimum Efficiency Reporting Value) rating scale but it can easily translate to other measurement scales that you may see used. MERV vs. MPR Any filter rated on the MERV scale is 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. They are comparable to AC furnace filters with the rating of MPR 2800 and FPR 10. Reduce Allergens with an Air Filter Checkup and More! 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. Different companies have different rating systems. MERV 15 pleated air filters capture most airborne particulates such as lint, dust, pollen, bacteria, pet dander, dust mites, mold spores, smoke particles, viruses, coughs and sneeze, smog and other contaminants. The higher the rating, the smaller the particles the filter catches. A filter with a MERV rating of 13 to 16 is considered a high-ranking MERV filter and can remove up to 75 percent of all airborne particles 0.3 microns or greater from the air. 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). HEPA is a type of pleated mechanical air filter. MERV stands for minimum efficiency reporting value. All filters sold must meet basic safety expectations, and most brands have higher-level filters to address particular needs and situations. ... MERV vs. MPR rating. Filtrete (3M) filters are the only filters that carry the MPR rating and there is currently no independent third-party testing available for comparison to MERV … MPR vs MERV; Don’t let smells get you down. MERV vs MPR and FPR. Here’s how MPR stacks up with the MERV rating. Of the two MERV 8 Flanders filters tested, the 2-inch Pre-pleat performed marginally better than the 1-inch NaturalAire. Ratings go from 4 to 10 and are very similar to MERV ratings. They’re just different ways of comparing the same filters. MPR stands for Microparticle Performance Rating, and it’s how Filtrete™ Brand reports a filter's ability to pull in and trap tiny particles between 0.3 and 1 micron in size. of Energy). Hey, it’s going to be okay. All home air filters use some kind of rating to tell you how fine of particles they’ll filter out. What is HEPA? All filters have a MERV rating. MPR ratings (ranging from 300-1900) also gauge the size of the particles they will remove from the air, but only from 0.3-1 micron in size. The measurements are similar to MERV. MERV vs MPR vs FPR . Nov 06, 2019. Nordic Pure MERV 12 vs Filtrete MPR 1200. MERV vs. MPR vs. FPR: WHAT THE HECK DOES IT ALL MEAN? MERV – or Minimum Efficiency Rating Value – is the standard that most companies use. As air moves through a building’s HVAC system, air filters trap and collect large and small particles such as dust, allergens and microorganisms. Many HVAC companies and distributors offer filters with a MERV rating between one and 20. MPR is helpful when comparing one 3M Filtrete filter to another, but it does not directly translate to MERV. The Microparticle Performance Rating (MPR) vs MERV vs FPR. MERV vs MPR Ratings. Microparticles matter — they can make up to 99% of what we breathe. For instance, an MPR 1000 filter will block 41% of E1, 77% of E2, and 88% of E3 particles. MERV isn’t the only performance rating that you might run into when shopping for a furnace filter. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), this filtration helps provide healthier indoor air quality.A filter's MERV number indicates how it's rated to remove these particles. Notice I said most. Surprisingly, the 4-inch Filtrete 1550 (MERV 12) was only marginally better than the 1-inch Filtrete 1700 (also MERV 12) and the two other MERV 11 filters of the same brand (1000 and 1085). HEPA, or High Efficiency Particulate Air filters, are designed for applications where … Air filters with higher MPR ratings will block more particles than air filters with lower MPR ratings. MPR Rating , or Microparticle Performance Rating, was developed by a large manufacturer to grade their air filters based on the ability to filter air particles smaller than 1 micron. 3M decided to make things difficult by coming up with their own rating system. The smaller the microparticle, the more difficult it is to capture and the longer it stays in the air (or our lungs). It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. For more information on MPR ratings and how they relate to air filtration efficiency, check out 3M’s guide to MPR vs MERV filters. 3M filters focus strictly on the latter—the submicron particles, and they use a rating system called MPR. The MPR filters use a series of numbers to gauge the size of the particles they will remove from the air and concentrates on particles only ranging in size from 0.3 and 1 microns. Scale from 1-20. The most common measurement scales that you will find are MERV, MPR, and FPR. MERV, MPR, and FPR are rating systems for air filters. Seriously, we’ve got enough going on right now that there’s no need for the air filter alphabet soup — or today’s headlines — to get you down. The higher a MERV rating, the higher percentage of a particles removed from the air. 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. They are all based on the size of particles the filter is able to capture. MERV, MPR, and FPR air filters: What’s the difference? MERV Rating is the established air filter industry rating system, but, some companies have developed their own rating systems, based on the ASHRAE MERV Rating. MPR: Micro Ratings go from 4 to 10 and are very similar to MERV ratings. reply Allison Bailes 1. As with any industry niche and product there’s always some revelations that come naturally on the learning curve. My recommendation is to buy filters with a MERV rating whenever possible. The purpose of the MERV standard is to permit an "apples to apples" comparison of the filtering efficiency of various air filters. Difference Between Ratings For Furnace Filters – MERV vs. MPR vs. FPR. The MERV rating on an air filter describes its efficiency as a means of reducing the level of 0.3 to 10 micron-sized particles in air which passes through the filter. There is no recommended rating scale at all from 3M for these filters. 800 MPR, 1000 MPR, 1085 MPR & 1200 MPR have a rating of MERV 11; 1500 MPR & 1550 MPR have a rating of MERV 12; 1900 MPR & 2200 MPR have a rating of MERV 13; 2800 MPR has a rating of MERV 14; FPR or Filter Performance Ratings were created by The Home Depot. Stepping up to a MERV 12/MPR 1200 filter is a good idea when air quality is important. MERV Ratings vs. MPR vs. FPR Posted by Michelle Eld on 26th Sep 2016 There are lots of acronyms out there to describe filter ratings, and they can all be a little confusing. The MPR system of ratings was created by and is only used by 3M. Any air filter you purchase will have a grade on it as a tool to show its quality. So, if you have pets, kids, or people with allergies in your home, this is a great combo of air quality improvement and value. Here I will help you understand these three abbreviations. Here’s some added context to illustrate MERV vs FPR vs MPR ratings, the purpose of air filter pleats, and some key differences between brands.

Only filters under the 3M brand contain an MPR rating. And the first thing to understand about each is that they are not for different kinds of filters. Catch More: MERV 11 - blocks particles = 1.0–3.0 μm (1900 MPR, FPR= 9/Purple) 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 … These are the most popular rating systems of furnace filters on the market today from the American Society of Heating, Refrigerating, and … The published MPR Rating numbering system is a scale of 0 – 2700, with their highest published furnace filter equaling the Nordic Pure MERV 13.
