Abstract
An air filtration system includes a light weight container which stores a quantity of water for filtering contaminants from inhaled air. A coupling assembly is used to connect the container to a flexible hose for delivery of the filtered air to the dust mask worn by the user. The coupling assembly allows a user to interchange one light weight container with another in a quick and convenient manner if one container becomes saturated with contaminants. A user simply pulls downward on the slidable jacket to release the industrial plug and allowing the attachment of another container to the hose via the coupling assembly.
