The Particle Filtration Efficiency (PFE) test evaluates the inert particle retention or filtration efficiency of the filter medium and other filtration devices at submicron levels. This test is done on face masks and on all filter materials that allow 1 cubic meter per minute (CFM) flow to pass.
This test, also called Latex Particle Challenge, is required by ASTM F2100 and is performed in accordance with ASTM F2100 and follows the basic principle of ASTM F2299. EUROLABoffers a high level of expertise in PFE testing and is one of the rare companies to offer this testing. Moreover, EUROLAB can perform all required ASTM F2100 tests.
In the Particle Filtration Efficiency test, the filtration efficiency of filter media materials against submicron particles cannot be determined using particles that are difficult to apply. This procedure involves the generation of a particle aerosol using NIST traceable polystyrene microspheres with Particle Measurement Systems (PMS) Model PG-100 particle generator. Particles are counted with a PMS Model LASAIR II-110 or 310 laser particle counter.
The latex particles used in this procedure have a narrow standard deviation and the design of the PMS particle generator produces a consistent particle difficulty. The test is performed on a single particle size. EUROLABis capable of performing testing at 0.1 um, 0.3 um, 0.5 um and 1.0 um. ASTM F2100 specifies a particle size of 0.1 µm. The PMS particle counter is an optical laser-based device and operates at a flow rate of 1 cubic foot per minute (CFM) or 28,3 liters per minute (LPM).
