KO2 is also the active ingredient in a Chemox breathing apparatus used by many navies throughout the world. I instruct user in its operation every day and use literally hundreds of cannisters every month.
The compund does not have a smell in use or even when not activated. It is very dangerous and any hydrocarbons coming in contact with the KO2 will result in an interesting fireworks show, I also know that because we used to demonstrate what could happen before the navy decided it was too risky.
I expect your KO2 has been exposed to moisture and/or CO2 and has broken down.
I second that. We had potassium superoxide (KO2) canisters used in firefighting units when i was doing my National Servce in the Greek Navy. I think they were made by MSA - we used to call them OBAs (oxygen breathing apparatus). There was no noticable smell or after taste when using them. There must be something wrong with your lot.
Besides, as you rightly said, why would you want to take that stuff with you underwater anyway???
