    filter efficiency
  • method of expressing a filter's ability to trap and retain contaminants of a given size.

  • The efficiency of various filters can be established on the basis of entrapped particles; i.e., collection efficiency; or on the basis of particles passed through the filter; i.e., penetration efficiency.

  • The operating results from a filter as measured by various criteria such as percentage reduction in suspended matter, total solids, biochemical oxygen demand, bacteria, color.





    hepa
  • A high efficiency particulate air , or HEPA , filter is a type of high-efficiency air filter.

  • HEPA stands for High Efficiency Particle Arrestor, used to reduce the number of contaminants in indoor air. A HEPA filter will arrest or stop 99.97% of all particles .3 microns or larger.

  • short for High Efficiency Particulate Air – often used to refer to the level of filtration for vacuum cleaners or dust extraction.
