But.... load your scrubber, get blown out, and plan to dive in a week? Toss your powder out if you like, but it's no different being stored in the scrubber than in the keg.

Another data point: I work far more from a volume standpoint with coal mine safety rebreathers than diving rebreathers, and the scrubbers are packed for 5 *years* before a change, ands are carried *every day* on the belt of a coal miner. Continuing, the Biopak 60 and Biopak 240 rebreathers are used for hazardous environment entry and are stored *packed* for years. Ditto every IDA-59 in the Russian Sub Escape Kits, Ditto the RGU F/M scrubbers in the Warsaw Pact armored vehicles. They stay packed for years, and are relied on to save human life.

So, I'm *sure* yours can sit a week in your garage....

Very probably all true... I agree that Packed and In the Keg are pretty much the same.

The really vital question is if you dive your 3hour Scrubber for 1/3rd of its duration than park it how long can it be left, can it still be dived for 2hours, can you assume for every X days wait you reduce the remaining dive time by X hours etc?

The guy who was/is on here for Molecular Products skirted the issue IMO.

I think there should be some set figures for this the same there are for scrubber duration.

The vast majority of us seem to be getting away with whatever we're doing- its just crazy that we have numbers/limitations on almost everything except what a used scrubber is good for.
