I designed my personal scrubber to use the disposable canisters that fit anesthesia machines. They're clear so I can observe the color change. An anesthesiologist friend helped me in the design. Some of the inspiration came from a Biopak 45 I had modified for
diving as a rebreather. I have a larger one for when carrying a passenger.</div>
