RE: [PSUBS-MAILIST] ExtendAir scrubber cartridge
Alan,
It is very feasible to accomplish what you propose. Have done the same when
building rebreathers for diving.

Jon & Dean,
Wouldn't it be simple to make your own cartriges ?
Looking at your CO2 scrubber design Jon, you could make a couple of the
canisters that hold the absorbant & have an outer canister that they fit in
to.
The spare canister (cartrige) could be kept, sealed at the top & inside a
similarly sized screw top plastic container. Just take the new cartrige out
of it & the old one in it.
