Filtration Wikipedia

Filtration is a physical, biological or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate.

Particle Filtration Efficiency (PFE) Test Nelson labs

In Particle Filtration Efficiency testing, the filtration efficiency of filter media materials against sub-micron particles cannot be determined using viable challenge particles. This procedure involves the generation of a particle aerosol using NIST traceable polystyrene microspheres with a Particle Measurement Systems (PMS) Model PG-100 particle generator. The particles are counted with a
