How to Pick the Right 20x20x1 Air Filter for You Using the MERV Rating System
The MERV (Minimum Efficiency Reporting Value) rating system was designed to help tell how well an air filter(also known as an AC filter or furnace filter) removes particles from the air. Higher rated filters are more efficient at removing a larger percentage of smaller particles from the air each time it passes through the filter.
What is MERV rating of the filter in your home? You may not even know because, more often than not, the company that services your HVAC system replaces the air filters during the service call. In many homes each air return has a grill that opens so that you can replace your air filter(Your filter may be in the furnace instead of in a return grill in the wall).
Good air filters can protect the air quality in your home and do not have to be expensive. You can buy 20x20x1 Air filters in bulk(a case of six) and save a considerable amount over what you may pay at ACE Hardware or Lowes for a single filter.
The EPA says about MERV 6 is the level that begins to protect air quality, so MERV 8 is a good minimum level for an air filter if you want to begin to protect your air quality. A minimum of MERV 11 is usually recommended for allergy suffers. MERV 13 is usually found in high end residential, hospital common areas, and high end commercial building that are LEED certified.
