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.
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.
