Brands that manufacture electronic furnace filters include UAF, Honeywell and EnviroSept. The EnviroSept electronic furnace filter air cleaner is among the best known of these brands and, according to the manufacturer, has high efficiency at removing particulates from the air.
Electric furnace filters can take the place of standard fiberglass air filters. They operate by using an electric charge to attract a greater number of particulates, thereby decreasing the amount of dust, pollen and other allergens in the air.
Typically, installation requires nothing more than inserting the electric furnace filter into the furnace and plugging it directly into the furnace power source. Some furnaces have an outlet available for electric furnace filters. However, those who are interested in using an electric furnace filter should know that some installation, such as minor changes to the duct work of the furnace system, may be required in order for the new filter to work properly.
Electric furnace filters include a removable filter component that can be washed by hand or in a dishwasher. Unlike standard filters, which should be changed out on a monthly basis, an electric furnace filter typically only needs to be cleaned twice per year. Homeowners who choose to use an electric furnace filter can switch back to a standard fiberglass filter with a minimum amount of effort.
