An electrostatic air filter uses electrostatically charged polypropylene and polyurethane filtration medias to attract particles as small as 3 micron. A safe static charge is produced by forcing air across the filter. This static charge attracts and traps airborne particles into the filter just like a magnet.

Outlines:
Achieves high efficiencies mainly through electrostatic attraction with film
   charging-splitting technology
Also utilizes mechanical capture mechanisms
Open construction – High loading
Rectangular fibers – Higher surface area
Polymer-based – Not fiberglass
Performs best for applications demanding high efficiency and low pressure
   drop

Benefits:
Maximum charge density and charge stability
High particle capture efficiency
High loading
Low pressure drop
Resistant to moisture and degradation
Non-toxic
