Beyond HEPAs: Chemical Filtration for Cleanroom Applications

  Have this course taught at your facility!

Today's cleanroom design is such that one can essentially eliminate particulate contamination through the proper combination of filters up to and including HEPA and ULPA filters. Whether it’s dust, smoke, pollen, mineral, metal, viable or nonviable, particulate control is generally accomplished by mechanical filtration principles. This is not the case, however, for the control of chemical (molecular) contamination. Effective chemical contamination control typically requires the application of both physical and chemical removal mechanisms employing principles of adsorption, absorption, chemisorption, ion exchange and/or catalysis. Chemical filter manufacturers are offering a large number of control options from which the facility, process, and contamination control engineer must decide which is the best solution for their specific applications. This presentation examines the various types of chemical filters available, their relative strengths and weaknesses, and the results of independent evaluations for a number of different chemical filter types. Several contamination control strategies employing chemical filtration will be discussed.
