Paper Media: This expandable paper media traps smaller particles and provides a higher efficiency starting around 40% and increasing as the filter traps contaminants. Paper media can come in depths of 1” up to 4” that is usually placed in a special cabinet.

Electronic: This filter uses a mesh prefilter to capture large particles and electrically charged ionizer wires that charge smaller particles so they become attracted to the metal plates in the main part of the filter cabinet. There is also a new style of electronic that incorporates the paper media style. These filters can remove up to 98% of contaminants.

HEPA: This filtration system was designed by the Atomic Energy Commission during World War II to remove radioactive particles from the air in manufacturing plants. In order to earn the HEPA designation the filter must be capable of removing 99.97% of all airbourne particles by particle count at a size of .3 microns. This type of filter is mainly used in burn centers, operating rooms, laboratories and other areas where strict air quality is mandatory.

UV Lights: The ultra violet lamp is now being used to kill harmful bacteria, fungus and mold growth in your coil. When used together with a higher efficiency air filter it can be a tremendous addition to your air cleaning system.
