MERV: If you don't already know the meaning of MERV, here is a definition: Simply stated, the higher the MERV number, the more efficient the air filter will be in removing contaminants and pollutants from the airflow in your home or office. A MERV 13 air 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. Finally, keep in mind that the MERV rating has nothing to do with size. MERV 8 and MERV 11 and MERV 13 are all the same size air filters for any given model number.

Caution, Ordering The Right Size:  Measure your existing filter because the size written on the frame may, or may not be the true size. Depending on the manufacturer, the size on your filter frame could be "Nominal" (by name only) or "Actual" (true size). For example, a 20x24 "Nominal" filter will measure 19 1/2 x 23 1/2. On the other hand, a 20 x 24 "Actual" filter will truly measure 20 x 24.  If you need a "Nominal Size", but order an "Actual Size", the filter you get will not fit

Custom-made Filters:  If you do not see your size in the table above or find it in our search engine, we can make a special custom-made air filter for you.  Just email us the exact size, and we will get back to you with the price.....Custom-made filters cannot be re-stocked, so for that reason they cannot be returned if you order the wrong size,  So, please make sure that you order the right size. .
