Studies show that indoor air pollution is one of the top five environmental health risks. Changing the air filters is not all that hard for most people, it takes about five minutes and requires no tools in most cases, but is one of the most important things to keep in mind for your air clarity and your health. The most important things to keep in mind when changing filters is knowing how often to change them, and knowing what quality air filter you’re buying. There are three ratings systems: MERV, MPR, and FPR. MERV Rating (Minimum Efficiency Reporting Value)  MERV is the primary rating system used in the industry, both domestically and internationally. 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 MPR (Micro-Particle Performance Rating)   MPR is a rating system developed by 3M. It rates the manufacturer’s filters and their ability to capture airborne particles smaller than 1 micron FPR (Filter Performance Rating)  is a rating system developed by The Home Depot for brands sold through their stores, including Honeywell. It utilizes a color and number scale from 4 to 10 that closely resembles MERV rating This chart will help you understand how the ratings are comparable to each other MERV MPR FPR Efficiency Frequency 6 300 n/a Captures dust and pollen 30 Days 8 600 5/Green Dust, pollen, dust mites, lint 90 Days 11 1000 7/ Red MERV 8 + mold spores, bacteria,
