Not sure if the same thing happen in the US, but distilled water is becoming harder and harder to get, in profit to the demineralized one.

Not certain how identical it is, but it is publicized as being a replacement.

Now H2O or not, demineralization costs more than distillation. A gallon of distilled water is between 99 cents and 2.75$; while the cheapest gallon of demineralized i saw was 5.75$

Now, I asked why thry don't have distilled. ... no answer. I bought elsewhere.

Questions:

Do you have the same issue locally?

Does demineralized water really do the same as distilled?

How often do you buy these? Its been ages since my last purchase...

Just distilled around here. My understanding, which is very possibly wrong, is that "distilled water" will be mineral free due to the distillation process, where "demineralized water" will be free of mineral due to any process that achieves such results. Could still be distillation, or RO, or something else all together.

I don't actually understand the question. if you found distilled water, don't use demineralized water.

Reverse osmosis

Which I am pretty sure I read on one of them bottles when I first saw them a few years ago (but kept buying cheaper distilled water anyway)

So you're saying a gallon of water, the most abundant resource on the planet, costs more than a gallon of gas in Canada? I don't know whether to laugh or cry.

One would think it would take less to get a gallon of tap water to pure water, than a gallon of crude oil to petroleum. Just saying. I'm not a chemical engineer though.
