Abstract
This invention pertains to a protective helmet having a plurality of vents therein and air supply tubing and filtration element for supplying filtered air to a user. The air supply tubing is connected to the filtration element mounted in the helmet and delivers this filtered air through an inlet one-way valve and a mouthpiece to the user upon demand. The inlet and an exit one-way flow valve maintain the proper flow direction during the inhale and exhale phases and prevent any back-flow from occurring.
