Abstract

A bactericidal after-filter device that mounts generally parallel to and downstream of an air filter of an air duct circulation network of a living enclosure includes a body having a front-screen element facing a back-screen element that allow for the filtered air to freely flow there through. A bactericidal medium, such as fibers forming a layer of angel's hair, is contained in between the front- screen and back-screen elements of the body and has a porosity that provides substantially no obstruction to the filtered air flowing there through while it locally retains and kills the air-suspended bacteria therein.
