Enhance Indoor Air Quality With Advanced, Washable Filter Cells

The Performance Electronic Air Cleaner removes airborne particles as small as 1.0 microns, including smoke and dust particles normal disposable filters can't. The air filter cells of this air cleaner can also be washed, saving you money on replacements.

ELECTRONIC AIR FILTERS
Air filters are available for units that are permanent, disposable, and reusable. Some filters have a very low static which will allow the maximum free air flow through the filter while providing a minimal amount of filtration. For occupied spaces where allergens, pollen, and mold are a concern, filters with a finer mesh are recommended (HEPA filters). Filter thickness is usually 1 in for residential systems.

AIR FILTRATION
Air contaminants are of many types, including dust, fumes, smoke, mists, fogs, vapors, and gases. As the mechanical filter clogs with dirt, airflow is reduced where the cooling coil will freeze, causing the compressor failure or not cooling. In a heating system, dirty filters can cause overheating and reduce the life of the heat exchanger or causing to trip the high limit switch. QASC recommend changing or cleaning the filters at least twice a year, before winter and before summer. In some areas of higher use, filters may have to be replaced or clean every 30 days. QASC offer to the customers regular schedule maintenance in residential and commercial HVAC-R

RATING AIR FILTERS
There are three ways of rating:
1) The efficiency is determined by using procedure set up be ASHRAE
2) The Resistance is measure with a manometer. The gauge on the instrument indicates to change
3) Particulate Holding Capacity is the length of operation
