The CO2 Scrubber in a Diver’s Rebreather
How long a CO2 scrubber lasts during a dive depends on many factors. I will mention some of the ways that CO2 can be removed from the breathing gas. I will also discuss ways to measure how long a scrubber will last (called the endurance time) and some of the factors that change it, but first will discuss why it is necessary at all.
