The lower MERV, like MERV 8, do not efficiently filter particles this size. Once a filtler begins to filter these small particles (0.3 – 1.0 microns) it is at a level of about MERV 13. Same thing, different package! This “system” has the same flaws as the Home Depot FPR no way to verify, no standard test data available and NO AIRFLOW data!Īlso, MERV does take into account the smaller particles. The MPR only takes into account the tiny microscopic particles between 0.3 and 1 microns. The MERV system measures a filter’s ability to capture large particles. ![]() MPR is different from MERV, the Minimum Efficiency Reporting Value. The higher the MPR, the better the filter’s ability to capture particles from the air as it passes through the filter. The MPR system helps you compare Filtrete filters based on the level of air filtration you want. Just make sure you buy the correct filter based on the science you have learned and don’t switch to a “premium” filter in the store after you see the pretty blue stripe!ģM developed the Microparticle Performance Rating (MPR) system to demonstrate a filter’s ability to capture the smallest airborne particles-from 0.3 to 1 micron in size from the air passing through the filter. You can probably buy the correct filter for your system, that you have determined ahead of time, at Home Depot. Home Depot sells some pretty good filters they also sell some very bad filters. Having said all that let me now say this. ![]() But Robert, it catches more particles! Fine, so does a piece of cardboard but if you use a piece of cardboard the system will die!įourth, it is more marketing hype than science! We are smarter than this don’t fall for it! There is no way in this rating system to determine if a filter is going to restrict airflow or not. Third, the Home Depot FRP System does not address AIRFLOW! As we have seen, airflow is CRITICAL to system performance and filter performance. Second, there is already a standard for comparing filters, the Minimum Efficiency Reporting Value, or MERV! This is based on a standard test that all filters must use to determine the MERV. First, they claim to have these filters tested by a third party testing facility but they do not publish the test results, just assign a “rating number”.
