The filtering materials used in the filter makes a difference in efficiency. When we refer to efficiency, we mean how good a filter is at removing particles from the air flow. The more efficient, the smaller the particles the filter will trap. A national organization, ASHRAE, developed the standard for testing filters. With this test, the results are expressed in MERV (minimum efficiency reporting value). Simply stated, the higher the MERV number, the more efficient the filter will be. A MERV 13 filter is more than twice as efficient as a MERV 8 in removing contaminants 1 micron in size. To understand how small 1 micron is, a human hair measures 100 microns. Odor-Ban is a MERV 8 impregnated with activated charcoal. This makes the filter about a MERV 9. A filter with Activated Charcoal will remove foul odors and harmful gases found in a home or office, as well as particulate matter. Finally, keep in mind that the MERV rating has nothing to do with size. MERV 8, MERV 11, and MERV 13 are all the same size filters. |
