Exhalation Valve Caps: Our exhalation valve caps are an alternative to our standard V1 and V2 one-way exhalation valves.
Exhalation valve caps do not allow any air to pass through the valves – causing 100% of your exhaled breath to pass through the mask filter. This design helps to further prevent the spread of airborne particulate or germs to those around you.
