Re: [PSUBS-MAILIST] Methane scrubber
Some sort of activated-charcoal type filter would probably
do the trick:
http://www.luftfilterbau.de/English/E-Aktiv/aktivk1.htm
It also mentions adsorping "diesel oil fog" and gasoline
pollutants from the air, in it's not very scientic looking
"effectiveness table". This might be something to consider
if you have a diesel or gas engine onboard. I've heard
that spending time with a (running) diesel engine in a
small space isn't much fun smell wise.
