Description
RZ® Dual Valve Technology:A one-way airflow vent expels condensation keeping the 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.
The 2.0 Replacement Exhalation Valves are made of thicker plastic, providing added durability. The 2.0 Replacement Exhalation Valves also hold the diaphragms in a section of the valve separate from the portion that opens to change the filters. This decreases the occurrence of the diaphragms going missing.
