Abstract:
A filter media including a scrim, a polytetrafluoroethylene (PTFE) media substrate upon the scrim, and a layer of expanded polytetrafluoroethylene (ePTFE) membrane adhered to the PTFE media substrate on the scrim. The filter media is pleatable and has air permeability of approximately 3-10 cubic feet/min at a 0.5 inch H2O pressure drop and an original filtration efficiency greater than 99.0% when tested in an unused, unpleated condition with a 0.3 micron challenge aerosol at a flow rate of 10.5 feet/min and when tested after a cleanable dust performance test according to ASTM D6830.
