Merv 14 Furnace Filters
 MicroSponge® filters have a special blend of polymers to create a high, stable active charge on every fiber of the air filter. This charge causes pollutants to stick to the filter, like a magnet to steel.  The charged fibers do not need to be as tightly woven as in ordinary filters, this means they will not restrict airflow. MicroSponge filters have the highest efficiency and the lowest pressure drop of any charged media in the world. |
