Title (EN) MICROBICIDAL AIR FILTER
(FR) FILTRE A AIR MICROBICIDE
Abstract:
(EN) Microbicidal air filter (10) for use with an air passageway, which includes an immobilization network (12) including a plurality of fibers (20) having an amount of at least one antimicrobial agent incorporated and molecularly bonded into a structure thereof sufficient to substantially immobilize, retain and at least inhibit the growth of, or typically kill, microbes suspended in a volume of air moving through the air passageway. The immobilization network (12) is substantially permeable to air. A microbicidal facemask (24) and a microbicidal air filter (10) used in an air circulation system (40) using the immobilization network (12) are disclosed.
(FR) L’invention concerne un filtre à air microbicide (10) destiné à être utilisé dans un passage d’air, ce filtre comprenant un réseau d’immobilisation (12) comportant une pluralité de fibres (20) dont la structure incorpore par liaison moléculaire une certaine quantité d’au moins un agent antimicrobien suffisante pour immobiliser sensiblement, retenir et inhiber pour le moins la croissance ou, typiquement tuer, les microbes en suspension dans un volume d’air traversant le passage d’air. Le réseau d’immobilisation (12) est sensiblement perméable à l’air. L’invention concerne également un masque facial microbicide (24) et un filtre à air microbicide (10) utilisés dans un système à circulation d’air (40) employant le réseau d’immobilisation (12).
