[PSUBS-MAILIST] scrubber

[Alan via Personal_Submersibles]

Hank,
One of the main concrete water tank manufacturers in Australia was looking in 
to using their tanks for dual purpose, water storage & emergency safety room in the event of a forest fire.
Great idea as you could try & save your house & then climb in to your tank at the last minute. They said the thermal insulation from a fire was really good.

I want a charcoal filter as well, and I would like the CO2 scrubber to do both jobs.  Is there any reason I can not mix activated charcoal with absorbent.  Is it better to have separate layers of media?
