Alternatives to a Standard 1" Furnace Filter

The relative efficiency of air filters is rated on a standardized series of tests known as ASHRAE 52.2-1992.

Standardized Filter Systems

This method reduces contaminates by simply pushing the air through the media to trap particles. The smaller the pores in the media, the more particles it will take out of the air. Most fiberglass filters have very low efficiency and are not rated by ASHRAE because they take less than 20% of particulates out of the air.

What is an Electrostatic Filter?

The operation of an electrostatic filter is based on the principles of static electricity. A static charge is developed as air flows over a polypropylene mesh. The charge attracts all air borne particles like a magnet as air flows through the filter. Based on ASHRAE standards, this 5 stage Envirofilter electrostatic filter removes an average of between 90% and 97% of air contaminates.
