How long can you expose a scrubber to air?

[Mobulai]

Not sure why people keep bringing this topic up over and over

Given the popular demand for more info and tests and data about this cluster of topics (reusing sorb); I’m opening up donations to build a SNORT machine

I was already planing to build one for a few months (almost a year actually), but it’s a pricey endeavor and each test run costs so I’m still saving for it; I’m open to running all sorts of test variations (to those interested and willing to supplement the consumables costs)
You wanna try the impact of repacking sorb? Sure; adding sawdust to it, why not — let’s get these questions answered once and for all
(Not sarcasm)

Personally the most Id do is reuse yesterdives sorb if both last and next dives are less than 90mins — in hot dry environment like Dahab; and the snort is intended for canister design verification (someday I wish to make my own)
But resources can be managed well by sharing

Whoever is intrigued and feels generous just write me

Sorb is constantly “degrading” if you think about it. Whether it’s in a dry unit, moist unit, or the tub.

"Constantly degrading" seems rather inaccurate. In the tub (once recapped), after the CO2 is converted, it stops degrading -- the reactants are no longer present. A closed canister is no different as it is also sealed (just with a bit more volume).
