Electronic Air Cleaner Prefilter and Afterfilter Upgrade Kit
Create the ultimate air filtration performance in an Electronic Air Cleaner with our superior prefilter & afterfilter upgrade kit.
The electronic air cleaner installed in a ventilation system is a highly effective particulate air filtration system, specifically designed to remove small particles from the air. However, many of the most common allergy irritants (mold, pollen, pet dander, lint and household dust) are fairly large particles averaging 10 microns and up in size. As larger particles build up on the metal collection plates, the air cleaner rapidly loses it's efficiency and must be frequently cleaned to maintain peak performance. In addition, larger particle deposits can break off and be blown through the air cleaner instead of being captured by the unit, or can cause high voltage arcing which produces a snapping sound in the ductwork.
Independent testing shows that using a higher efficiency, washable, electrostatic prefilter will significantly enhance the working efficiency of the electronic air cleaner, without affecting the air flow requirements. In addition, the air cleaner is able to perform more effectively for longer periods before needing cleaning. An activated carbon afterfilter is recommended to adsorb any odors/fumes being recirculated through the home and to capture particles which did not take an electrical charge. The afterfilter also removes ozone emitted from electrical discharges and captures ash "brush-off" from the plates. The afterfilter will need to be changed as often as needed for ongoing odor problems. Kits are made to fit any model electronic air cleaner, i.e., Honeywell, Goodman, Trion, Trion Air Bear, White Rogers, Carrier/Bryant, Trane or Lennox.
Initial static pressure with Permatron prefilter 0.09 in w.g. Independent testing shows 40% increase in average Dust Spot Efficiency using Permatron prefilter versus metal mesh.
Measure existing filter for exact dimensions needed to fit your system. The disposable activated carbon afterfilters are available in 4-packs. Depending on odor and fume levels, these panels should be changed every 3-4 months in the average household.
