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. A microbiological interception enhanced filter medium of the present invention provides greater than about 4 log viral interception, and greater than 6 log bacterial interception.
L'invention porte sur un milieu de filtration amélioré par l'interception microbiologique et comprenant une structure microporeuse ayant une voie d'écoulement moyenne inférieure à environ 2 microns et fabriquée dans une matrice de particules actives. Sur une partie au moins de la surface de la structure microporeuse est formé un agent améliorant l'interception microbiologique et comprenant un matériau cationique en combinaison avec un métal biologiquement actif. Le milieu de filtration amélioré par l'interception microbiologique est supérieur à une interception virale d'environ 4 log et supérieure à une interception bactérienne d'environ 6 log.
