MERV 12 furnace filters are comparable to HVAC filters with the rating of MPR 1500-1900 or FPR 9. While different companies use different scales to measure the air filter’s efficiency, chose to follow the industry standard, MERV, as developed by ASHRAE (the American Society of Heating, Refrigeration and Air Conditioner Engineers). No matter the name of the rating, the efficiency of all air filters is rated according to the same criteria as set forth by ASHRAE. furnace air conditioner filters are manufactured using a heavy duty, moisture resistant beverage board frame. As with all furnace air conditioner filters, the material is electrostatically charged to attract unwanted particles. The media used will not promote the growth of bacteria or mold on the air filter and is better at trapping airborne particles than fiberglass filters. Our attention to the smallest of details results in a healthier living space. For fresh, clean air in your home and office, it is important to regularly change your AC filter, especially during home improvements. We recommend changing your HVAC furnace filter every 1-3 months, depending on your unique home or office environment. People with pets or those who suffer from allergies should change their A/C air filters more often. Replacing your air filter regularly not only improves indoor air quality, it helps your HVAC unit perform more efficiently. Important Note: Almost all air condition filters have a different Actual Size (the exact dimensions) than Nominal Size (the name) printed on the air conditioning filter. It is best to measure the exact size of your A/C filter and compare it to our Actual Size to be sure your HVAC replacement filter fits! 。。。
