Uh.....what planes are you on where you, the passenger, can simply "pull down the oxygen mask"? Also, wouldn't the P95 only help with particulates (e.g. soot),

- OutOfHere 9mo ago> but not with the actual toxic fumes? 3M 8577 has a bonus carbon layer for this purpose. Its protection is not complete, but can limit the damage. You should also carry spares in case the carbon layer is exhausted.
- AgentK20 9mo agoOh, very cool. TIL. Thanks!
- kubelsmieci 9mo agoHow will you know that you should change mask?
- OutOfHere 9mo agoThe mask itself starts to smell. You will start sneezing and also dripping from the nose, but this will stop if you remove or replace the mask. Also, you start to smell the diesel fumes. The more you wear a clean mask, the more sensitive your nose becomes to mild fumes.
- janice1999 9mo agoOP has no idea what he's talking about. Passengers masks are for depressurisation events and oxygen supplies last 15 minutes - enough time for the pilots to descend. Pilots have a separate longer lasting oxygen supply. In many (most older?) planes, a single passenger activating their mask will activate the chemical based oxygen supply that feeds all passenger masks.
