Which To Choose?
We offer high quality air filters for every need and budget. What's your main concern? Is it providing high quality filtration for your air conditioning equipment? MERV 6 or 8 is for you. Do you what to provide the best possible protection for your system, and address indoor air quality as well? Then consider upgrading to MERV 11. We will be offering a MERV 12 option in the near future. The higher the MERV rating, the higher the filtering efficiency.
*MERV Rating: Minimum Efficiency Reporting Value. A number assigned to represent the filtering efficiency of a particular filter, from a testing method designed by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), to help people compare the filtering quality of filters. Usually, the higher the MERV rating, the better the filtering performance
