Teaching with rescue masks can get costly when you have to replace expensive valves. Now you can get the most from your training dollars with WNL's affordable, single-use Practi-VALVE. These convenient, one-time-use valves feature a unique air filter that obstructs the flow of contaminants. The Practi-VALVE fits on the inside opening of all WNL adult masks, as well as our infant mask opening.
Each box contains 10 valves, which are individually sealed. Mask not included
