Given bulk prices of conc hydrogen peroxide, and human oxygen use, breating pure oxygen could cost around $3 per day for 5l 35% h2o2 (Order of magnitude numbers) However, this conc of h202 is quite dangerous stuff.
Powdered baking yeast will catalytically decompose hydrogen peroxide, and it shouldn’t be hard to tape a bin bag to a bucket to a plastic bottle with a drip hole to a vacuum cleaner tube to make an apollo 13 style oxygen generator … (I think)
(I am trying to figure out a cheap and easy oxygen source, does breathing oxygen help with coronavirus?)
Sodium Clorate decomposes into salt and oxygen at 600C, it is mixed with iron powder for heat to make the oxygen generators on planes. To supply oxygen, you would need 1.7kg per day. (plus a bit more to burn the iron) And it’s bulk price <$1 /kg. However, 600C would make it harder to jerry rig a generator, although maybe wrapping a saucepan in fiberglass...
