3M™ Cool Flow™ Valve
This proprietary valve is designed to release your hot, humid exhaled breath quickly, helping 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.
