Patent

CA 2287601

A vacuum cleaner filter bag exposes bacteria in incoming dirty air to bactericide throughout the useful life of the bag. Fingers provided on the interior walls of the bag are impregnated with bactericide. Air flow in the bag during vacuum cleaner operation causes the fingers to stand out from the wall, intercepting particles in the dirty airstream and exposing bacteria on those particles to the bactericide. The fingers stand out from the wall, and thus kill bacteria, substantially throughout the useful life of the bag, even after a cake of dust and dirt has formed on the inner walls of the bag.
