Doesn't that involve passing water through a bunch of plastic filters and then letting it sit in a big plastic holding tank?

- thsksbd 3y agoSure, but it works :) (except that one company that had a low quality membrane that leached ionomers, lol). Once plastics have leached off their manufacturing chemicals they really are very benign. The membranes you mention are permeable, basically, only to water. Salt ions are pretty small - if the membrane blocks salt ions, they're going to block just about any molecule [1]. 1. for the most part. You can have a molecule that dissolves in the polymer membrane and therefore gets through. A great example is polymer self-diffusion itself (fairly slow) and very short chains of the polymer (faster). But, generally, polymers don't like to mix with anything but themselves (see Flory-Huggins and DeGennes).

- lost_tourist 3y agosure but you can buy tablets to put them back in, drinking purely distilled water on the regular sound's really bland
- watersb 3y ago> drinking purely distilled water on the regular sound's really bland Also potentially dangerous. If you drink a gallon of distilled water all at once, it could screw up electrolyte balance. Screwy potassium levels can cause heart fibrillation. I would guess that the risk of water that's coming from reverse osmosis is safe for routine use, in the context of a healthy diet.
- djtango 3y agoIsn't distilled water also bad for your teeth?
- DoingIsLearning 3y agoFluorinated water is a US thing. People elsewhere do fluoride varnishes with their Dentists and that is absolutely fine and sufficient.
- vel0city 3y agoIts not just a US thing, other places in the world have fluoride in their water. In many areas fluoride just naturally occurs in the water at levels even higher than what managed services target. But other countries, such as Hong Kong, parts of Malaysia, Singapore, Ireland, parts of Spain, parts of the UK, parts of Canada, Mexico fluoridates table salt, most of Austrailia, Fiji is rolling out a program, half of New Zealand, about half of Brazil, and most of Chile all have some water fluoridation programs. Many other countries did at some other point in time but stopped doing it.
- putnambr 3y agoFluorinated water has its own health risks, but everyone should absolutely be using either a fluoride toothpaste or fluoride rinse.

- refurb 3y agoIf you drink a gallon of distilled water all at once, it could screw up electrolyte balance. No it won't. You get most of your minerals from your food, not your water. Distilled water has zero health effects.

- r00fus 3y agoFood contains minerals. You probably get more water from food than what you drink. My family lived on distilled drinking water for years with no mineral deficiencies. RO water isn’t as deficient as distilled.
- RetpolineDrama 3y agoWhy does this "minerals in the water are important" myth keep persisting? Do yourself a favor and calculate: 1) The specific minerals in the water you want to consume 2) The daily values for each of those minerals 3) Figure out the water you'd need to drink to meaningfully contribute towards hitting those DVs Hint: It's in the tens to hundreds of gallons of water per day for tap water. Filter the water and pop a multivitamin, expecting to get significant "minerals" from tap water is a joke.
