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.
3M™ Cool Flow™ Valved Respirators are ideal for long periods of wear, especially where conditions are hot, humid or physically demanding. Learn more and see the Cool Flow valve in action.
