Air filtration, as we all know, is the process of separating dispersed particles from air by means of porous media. Filter fibers are expected to separate and retain particles on or within the filter medium. An example of the use of air filtration is as a preventive measure to protect the respiratory systems of human occupants indoors as well as the HVAC equipment. This can be done through mechanical filtration to reduce contaminant concentrations, which vary depending upon the nature of the application and location. The success of any filtration system depends upon its ability to capture the right contaminants in the right quantity whilst presenting the lowest resistance to the airflow.
