HEPA Filter

High efficiency particulate air (HEPA) filters have an efficiency rating of 99.997% for collection at 0.3 microns. This filter is used for containment of particles—toxic powders, asbestos, lead, fingerprinting powders, etc. A HEPA Filter is an effective way to trap fingerprint powder while processing evidence for latent prints, as in our Identification and Basic Workstation. HEPA Filters are also used in the DrySafe Evidence Drying Cabinets to trap blood borne pathogens.
