MPR is helpful when comparing one 3M Filtrete filter to another, but it does not directly translate to MERV. Basically, the more particles that were trapped in the filter, the higher the filter’s efficiency. Even though they have completely different numbers, they are still air filters and can be compared directly against each other. MERV vs MPR and FPR. This rating describes how effectively the filters remove particles and … HEPA filters are typically only used for the absolute most stringent environments– such as hospital operating rooms, clean rooms for computer chip manufacturing, etc. 2-pack of MPR 2200 air filters. The MPR, or Microparticle Performance Rating system is designed to measure an air filter’s filtration of microparticles. The MPR rating system is an air filter rating system created by 3M. HVAC Training Shop is reader-supported. MERV stands for Minimum Efficiency Reporting Value. 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. 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. MPR was created and is used by 3M while FPR is created and used by Home Depot. 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). The goal of these tests is to give an accurate representation of an air filter’s performance at removing particles of different sizes. Also captures bacteria, smoke, and some viruses. MERV ratings extend from 1 to 16. 3M filters focus strictly on the latter—the submicron particles, and they use a rating system called MPR. At Air Filters Delivered, we label our air filters by their MERV filter rating. For each of these tests, the filtration efficiency is calculated as the ratio of particles measured after the filter to particles measured before the filter. The MPR filter rating system is intended to measure a filter’s effectiveness for particles in the PM2.5 range. MERV vs. MPR vs. FPR: WHAT THE HECK DOES IT ALL MEAN? MPR, or micro-particle performance rating, is a rating system developed by 3M. This is not to say that MERV filters are poor quality in reality they are more than adequate for the needs of most homeowners. Specifically, the system focuses on measuring a filter’s efficacy for particles in the 0.3 to 1.0 micron range. The E1, E2, and E3 particle groups are determined by ASHRAE standard 52.2. HEPA filters are tested and certified to filter out at least 99.97% of 0.3 micron particles. MERV isn’t the only performance rating that you might run into when shopping for a furnace filter. Here’s how MPR stacks up with the MERV rating. 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. 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 This rating is exclusive to filters that are manufactured and sold by the home improvement brand 3M in partnership with Filtrete. Their basic filter is rated at 100 and their most efficient filter is rated at 2800. The higher the MPR number, the greater the filter’s effectiveness at removing tiny airborne particles. The ability to capture a lot of th… The others are proprietary names. At 3M, we believe MERV only tells part of the story. 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. HEPA filters are able to filter out 99.97% of the smallest E1 particle on the MERV scale. FilterBuy MERV 8 Pleated AC Furnace Filter. 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. It rates the manufacturer’s filters and their ability to capture airborne particles smaller than 1 micron. The MERV rating system is the industry-standard rating system. As an Amazon Associate, we earn from qualifying purchases. 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. The main differences between the MERV and MPR filter rating systems are as follows: Even though MERV and MPR are different rating systems, some filters that are rated by each of these systems are directly comparable to each other. When considering FPR vs. MERV vs. MPR, you should know that the one thing they all have in common is that all are different rating systems for HVAC air filters. The MERV system is the only nationally regulated and independent filtration system. As you have already learned, the MERV rating is the primary rating system used in the industry, both domestically and internationally. APR 1550 Rating = MPR 1000 to 1200 Rating = MERV 11 Efficiency: Clean air of pet dander, smog and smoke The published MPR Rating numbering system is a scale of 0 – 2700, with their highest published furnace filter equaling the Nordic Pure MERV 13. (Best for Pet Dander) To describe FilterBuy’s furnace air … 05.27.2020. 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. These tiny particles of particulate matter are found in the air. 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. If you tried to use a HEPA filter in your home’s furnace, the airflow restriction from the filter would probably burn out your blower motor in no time at all.

The MERV filter rating is the domestic and international industry standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. To test a filter, an aerosol generator is used to spray particles of known sizes into an air stream. The main difference between the MPR and MERV rating systems is that the MPR rating system is focused on a filter’s effectiveness at removing E1 microparticles from the air. MERV: Minimum Efficiency Reporting Value developed by the American society of heating,refrigerating and Air Conditions Engineers. Air Filters Resources. 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. MPR, or micro-particle performance rating, is a rating system developed by 3M. 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. In order to keep your air clean in your home or business, it is important to install replacements frequently and dispose of your old filters properly. Comparing MERV, MPR, and FPR 13 ratings. The MPR rating system was created by 3M to measure an air filter’s effectiveness at filtering out microparticles. MERV vs MPR MPR, or Microparticle Performance Rating, was created by 3M to rank their filters’ ability to catch the smallest airborne particles. With our custom air filter wizard, you can build a size to fit your needs. The size of these particles is typical of dust, pollen, and mold spores.
