3M™ Cool Flow™ Valve

The unique 3M™ Cool Flow™ Valve releases your hot, humid exhaled breath quickly and thus helps prevent an unpleasant build up of heat inside a respirator.

The Cool Flow™ valve's ability to keep breathing cooler and more comfortable has been demonstrated through testing and thermographic imaging.
