MERV stands for Minimum Efficiency Reporting Value. What does this mean to you though? MERV is a
stardard ratings system set up by ASHRAE, the American Society of Heating, Refrigerating and
Air-Conditioning Engineers. MERV is a way of comparing the effifiency of air filters without having to
look at all the technical details provided by manufacturers. The higher the MERV rating, the more
efficient the filter. One important thing to keep in mind when comparing MERV ratings is that many companies DO NOT actually test their filters according to ASHRAE standards. They often come up with the number by testing larger particulate matter. Most common filters that you will see with a high MERV rating have NEVER been formally tested to verify this MERV rating. Camfil FARR prides itself on the fact that all of it's filters have been tested using the ASHRAE Standard 52.1-1992.
The first three filters listed above are standard in the industry for residential homes and lite commercial applications. MERV 6 is not as effective and is generally used when the filters are changed on a regular maintance schedule. |
