DustEater Washable Permanent Electrostatic Air Filter DE1212-1

DE1212-1 Overview

The DustEater® Air Filter series is proven in independent laboratory testing to provide highly efficient system-wide air filtration with low resistance to airflow.  Utilizing two electrostatically charged fabric panels separated by our unique ACCUMULATOR CHAMBER® produces a very effective three-stage filtration process. The first media panel (prefilter) attracts and holds airborne particulates. The filter fabric's inherent electrostatic charge enhances filtration by drawing particulates onto fiber surfaces like iron fillings onto a magnet. Static electricity, being static, does not flow like electrical current, and therefore does not discharge over time or require either grounding or insulation.  When particulates build up on the prefilter, airflow causes them to break off and be swept into the ACCUMULATOR CHAMBER, where turbulence and electrostatic forces cause agglomeration into even larger particulates. These agglomerated particulates are too large to pass through the second panel (afterfilter). The afterfilter attracts and holds the smaller particulates that may have escaped the prefilter, or do not respond to an electrostatic charge.

The DustEater (Model DE) is significantly more efficient than standard throwaway filters. Standard disposable filters trap only very large particles. Not only are these filters less efficient but they tend to clog, restricting airflow which results in increased heating/cooling costs. DustEater is environmentally friendly with no disposable parts.

The DustEater (Model DE), our allergy relief filter, contains a combination of polypropylene and non-woven polyester for increased arrestance efficiency, wire reinforced in a stainless steel frame.
