All home air filters use some kind of rating to tell you how fine of particles they’ll filter out. All filters sold must meet basic safety expectations, and most brands have higher-level filters to address particular needs and situations. Of the two MERV 8 Flanders filters tested, the 2-inch Pre-pleat performed marginally better than the 1-inch NaturalAire. MPR, or Micro-Particle Performance Rating, pertains only to products developed by the 3M company; typical MPR ratings range from 300 to 2200. Nov 06, 2019. Take a breath and whatever you do, don’t read the newspaper. 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. HEPA, or High Efficiency Particulate Air filters, are designed for applications where … The Microparticle Performance Rating (MPR) vs MERV vs FPR. There is no recommended rating scale at all from 3M for these filters. 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. They’re just different ways of comparing the same filters. 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). MPR vs MERV; Don’t let smells get you down. They are comparable to AC furnace filters with the rating of MPR 2800 and FPR 10.

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. Hey, it’s going to be okay. As air moves through a building’s HVAC system, air filters trap and collect large and small particles such as dust, allergens and microorganisms. MERV – or Minimum Efficiency Rating Value – is the standard that most companies use. 3M decided to make things difficult by coming up with their own rating system. For reference, an average strand of human hair is about 70 microns in size. Understanding the mechanics of air filters isn’t always easy. Here I will help you understand these three abbreviations. Reduce Allergens with an Air Filter Checkup and More! HEPA is a type of pleated mechanical air filter. 3M filters focus strictly on the latter—the submicron particles, and they use a rating system called MPR. 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. 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 … The FPR vs. MERV vs. MPR Rating Scales Filter-rating scales indicate not only the quality or the air filtration but also the specific types of particles removed. 1. The purpose of the MERV standard is to permit an "apples to apples" comparison of the filtering efficiency of various air filters. For example, the 5" deep Lennox Healthy Climate MERV 16 has about 40% less pressure drop @0.12" wc compared to the 1" 3M MPR 600 (equivalent to MERV 8) @0.21" wc. Air filters with higher MPR ratings will block more particles than air filters with lower MPR ratings. 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. MPR = Microparticle Performance Rating. reply Allison Bailes 1. And the first thing to understand about each is that they are not for different kinds of filters. For instance, an MPR 1000 filter will block 41% of E1, 77% of E2, and 88% of E3 particles. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. MERV vs MPR and FPR. 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. Many HVAC companies and distributors offer filters with a MERV rating between one and 20. All filters have a MERV rating. MERV stands for minimum efficiency reporting value. 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. The Microparticle Performance Rating or MPR is a rating scale created by Filtrete under the 3M company and it rates the filter’s ability to capture the smallest of airborne particles from the air (different companies use different scales). Ratings go from 4 to 10 and are very similar to MERV ratings. As with any industry niche and product there’s always some revelations that come naturally on the learning curve. of Energy). 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. FPR Rating , or air Filter Performance Rating, is a grading system that uses a color/number system on a scale of 4 (green circle) to 10 (blue circle). 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). TABLE OF CONTENTS MPR MERV Microparticle Performance Rating Minimum E˜ciency Reporting Value VS MPR 300 vs MERV 5 02 MPR 600 vs MERV 7 03 MPR 1000 vs MERV 11 04 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.
