whats your dumb purchases?

It’s also just a stand for a nozzle and a valve with really really overpriced CO2 cans
Check out this DIY fitting video to understand how it works and why you NEVER have to have a stupid sodastream to carbonate drinks
It’s exponentially cheaper to buy a 5 or 10 pounds refillable cylinder
and just fill existing 2 litres bottle

I theory yes, In practice nobody makes contaminated industrial CO² since the 1950s. If there are contaminant the gas supply will be VERY upfront about it. Usually it’s over 99.99% pure, very low moisture There’s also usually very few commercial sources of industrial gases in any particular town, so it’s usually not difficult to source it.
If you want to pay extra, then find “food grade gas”, it’s probably the exact same gas because the industrial gas is already so pure it meets food grade quality. Probably the only difference is the fitting is kept “food clean”
My gas guy gets it from “air liquide”, it’s a welding shop
And when you look at the product’s safety datasheet
It even already lists it as “food grade” They even list it as “100%” pure but of course, nothing is 100% pure.
It really depends on the production process,
Imagine of the production process intrinsically produces 3% carbon monoxide,
that would be very bad for inhaling !
But as industrial inputs that can be perfectly OK, as long as it is known, expected and dealt with.
But over time, gas manufacturer devised ways to make pure gas for the lowest price as any other production process.
So that’s the only gas that is available already, and has been for a long time.
That’s why I’m not worried about CO2 gas for the welding shop. The most likely contaminant is going to be a few milligrams of regular air
But yes in the abstract, you can’t use anything but certified food safe gas. The problem is that now your distributor needs to have food safe practices along the whole supply chain.
That means not the welding shop, because they’re not a laboratory or kitchen, they don’t have a food safe protocol for gas handling.
And the industrial distributor will not sell you any gas if you buy less than a couple tons.
So, in this case buying a sodastream cylinder retail is probably going to be your only option.
And that means paying 18$USD for 380 grams of CO2
Instead of paying 20$USD for 2270 grams
