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.
3M develops respirators with your comfort in mind. Cool comfort starts with cool breathing.
