[PSUBS-MAILIST] tampon filters

[Stephen Fordyce]

Hi guys,
I've spent a good amount of time messing around with HP breathing air
compressors (I have my own for SCUBA diving) and can volunteer these 2
links as explaining the final filtration process really well.

But in a nutshell, if you're going to be breathing it, especially if you
have to bail out at depth, I wouldn't be trusting my life to tampons... The
activated carbon and molecular sieve are pretty cheap, and much more manly
:).

Using an old hydraulic cylinder also has high potential for adding odours
to your air that no filtration will get rid of - there is some good stuff
about that in some the Airspeedpress books on diy oxygen systems.

Cheers,
Steve
