3M™ Cool Flow™ Valve

3M™ Cool Flow™ Valve

The 3M™ Cool Flow™ Valve is only available on 3M™ Respirators. Designed to release your hot, humid exhaled breath quickly, it helps to prevent an unpleasant build up of heat inside a respirator - a significant cause of discomfort to respirator wearers.

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