[PSUBS-MAILIST] air filter?

[Alec Smyth via Personal_Submersibles]

Hi Hugh,

It would work in either direction, but I would choose to use it blowing
*into* the scrubber. That would give the scrubber something to work on from
the first breath, whereas if you were sucking air through the scrubber, it
wouldn't have anything much to scrub until the entire cabin CO2
concentration rose. Also, exhaling through the scrubber I like the idea
that I wouldn't be breathing in any Sofnolime dust.


Thanks,

Alec
