To provide a filter medium having a microbiological interception function, filtration systems including the filter medium, and a method of manufacturing the same.
The invention is directed to a microbiological interception enhanced filter medium comprising a microporous structure having a mean flow path of less than about 2 microns and made of an array of active particles. At least a portion of the surface of microporous structure has formed thereon a microbiological interception enhancing agent comprising a cationic material in combination with a biologically active metal. The microbiological interception enhanced filter medium is provided with a viral interception of greater than about 4 log, and a bacterial interception of greater than 6 log.
