Dust Eater utilizes two electrostatically charged fabric panels separated by our unique
ACCUMULATOR CHAMBER to produce a very effective three stage filtration process. The first
Dust Eater 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. The heavy waffle weave of the polypropylene fabric
contributes to the filter's high dust holding capacity.
When particulates build up on the prefilter, air
flow 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).
Finally, the afterfilter attracts and holds the smaller particulates that may have escaped
the prefilter, or do not respond to an electrostatic charge.
The Dust Eater is significantly more
efficient than standard throw away filters. Standard disposable filters trap only very
large particles. Not only are these filters less efficient but they tend to clog,
restricting air flow which results in increased heating/cooling costs. Plus, Dust Eater is
environmentally friendly with no disposable parts.
