A one-way airflow vent expels condensation keeping the dust mask interior dry.
Each valve facilitates easy breathing outwards by optimizing airflow.
An easy-twist seal locks the inner filter in place and blocks unfiltered air.
Our Replacement Exhalation Valves are made of thicker plastic, providing added durability.

Great mask my wife liked it so much she took mine so had to buy another! Having extra valves is a must!
