How does the EnviroSept compare to the washable electrostatic filters found in stores and also advertised on radio?
Frankly, there is no comparison, as the EnviroSept is up to a thousand times more effective under normal operating conditions. Frictional electrostatic filters have been proven to be no more effective than standard throwaway fiberglass filters. In theory, the plastic/glass strands are supposed to develop a static electric charge as the air passes through the filter, much like when you comb your hair. However, you need very low humidity to create any type of low level static charge. This charge is quickly lost as soon as the filter collects any dust, which insulates the plastic/glass strands and prevents the generation of any static charge. It would appear that the only benefit these filters offer is that they are permanent. Further, you do have the dirty task of washing these filters every two-three months. In addition, these filters have been known to cause major air restriction problems after several years that may damage your heating/cooling system.
