Question Rebreather sanitizer

[Pavao]

I am in the "only when there is damage or stink" camp.
Stuff seems to last a long time if you don't leave things baking in direct sunlight, and have cool/dry storage.

Have ended all dive days with prompt rinsing, brief dilute steramine soak, freshwater rinseout, semi-diligent open air hanging dryout procedures. Water can remain in the corrugated hoses and counterlungs for several days. Might try the blower idea of @Pavao one of these days.

I believe that’s the key, drying it fast to remove the conditions which allows stuff to grow.
Makes me feel even safer knowing you just air dry yours and have had no problems.

Two and 1/2 years, about 150-175 hours, since certification... My original container of steramine remains unopened...

@stretchthepenn can confirm our instructor "recommended" following the manufacturers guidelines, but advised he seldom (if ever) did anything other than rinsing well with fresh water and allowing to dry (which is the key in his opinion). According to him, his incidence of respiratory issues was less than his colleagues who sanitized after every dive.

It's served me well thus far and I have no plans to change my routine.

Agreed, all around. We've followed our instructor's advice to stick with freshwater rinses, and we've had zero troubles. I've never cracked the Steramine bottle.

To be fair, I've also built a forced-air drying rig that dries the counterlungs thoroughly, so that may be part of my personal success story.
