>It's hard to find water filtration without plastic involved, hopefully other options will come to the market, but their offering is pretty good so far.

What about distillation as a filtration method?

Are the micro/nano plastics filtered by distillation?

Interesting what method of filtration the chip factories use, as they need 100% pure water for the cpu making process.

I've been drinking distilled water for a few years now, and the quality and peace of mind have been great. I documented it in https://www.nayuki.io/page/drinking-distilled-water .

Its not that interesting. Distillation works but its not healthy to consume. You could distill the water without plastics involved but then you need to add back minerals before drinking.

Debunked urban legend. Likely retcon from various mythology involving the chemistry lab's "deionized water" bottle which every chemistry teacher has to make up convincing reasons for the class not to drink from.

Maybe my thinking has been wrong. I always thought you would need to supplement for some of the minerals you might be getting from the water. I could be totally wrong here then, will need to do more reading.

Any water you drink is already very much hypotonic relative to your bodily fluids. Your minerals mostly come from your food, not your water.

I’m no expert on biology (I’m a chemist), but I drank quite a bit of DI water in grad school because the tap water was so gross.

Also, heavy water (D2O) tastes sweet. And it also won’t kill you when consumed, contrary to urban legend (at least not in quantities you can reasonably afford).

> Any water you drink is already very much hypotonic relative to your bodily fluids.

True. The saline solution used for blood injections has 9000 ppm of dissolved solids. Whereas tap water above even ~200 ppm tastes disgusting to me.

> I drank quite a bit of DI water in grad school

Nice... but I wonder if it's considered food-grade, and if there are any non-ionic / non-polar impurities in it.

> Also, heavy water (D2O) tastes sweet.

I find that plain distilled water tastes sweet too. I can't afford heavy water, but this YouTuber did: https://www.youtube.com/watch?v=MXHVqId0MQc .

> it also won’t kill you when consumed

Deuterium oxide will kill you only after deuterium replaces a significant portion of all your body's hydrogen atoms, like maybe 50+%. https://www.youtube.com/watch?v=fyK6kPi8k78

Isn't reverse osmosis also filtering out minerals?

[infecto]

Yes, and as another poster pointed out my thinking that the importance of those minerals might be incorrect. I always thought you needed to supplement on top of distilled water.

For RO, a lot of the systems include a mineral cartridge.

It’s for taste. Distilled water tastes like crap. I don’t know the science behind it, but “good” water (eg coming from hetch hetchy) tastes amazing in comparison.

100% pure water sucks the salts and electrolytes out of your body though, so you'd need to dope it again with some minerals

It's not a legend, it's just chemistry.

[mapt]

It's mythological biochemistry. It does not reflect empirical evidence.

Exercising in hot weather requires drinking electrolyte water to avoid hyponatremia. Drinking large amounts of soft or distilled water (around 6 liters) can lead to death.
