Isn't the purpose of the vent pipe to vent sewer gas? So you'd be breathing that rather than fresh air,

ges -- I think it's intended to be used if a fire has filled the air with smoke. In which case, sewer gas would be better than smoke.

A few things from the patent:
* This is intended for emergency breathing when there is smoke.
* There is an air filter in the design (no idea how good).
* Remember to blow out first to expel the water in the tube!
* It entered the public domain in 2001!
