In the case of Neil-Med, the documentation I have retained says to use previously boiled or properly filtered water (they provide some examples) when mixing. And they say not to use tap water. But they don't inform the user of the potential hazard of using otherwise safe-to-consume tap water. Worse, the bottle (mine is a squeeze bottle) doesn't have any reminder not to use tap water, at all. It would seem this would…

> But they don't inform the user of the potential hazard of using otherwise safe-to-consume tap water. Devil's advocate: if they did, odds are consumers would consider it as if the company is peddling conspiracy theories rather than actual science. Or "maybe it's true for tap water where the pots are made, but I trust my tap water and I know it's safe". If such explanations are more likely to harm a company's percept…

What nutrients does tap water have in it? Fluoride?

All kinds of minerals and such. In fact totally clean water, without them, is harmful and poisonous: "Drinking absolutely pure water can kill you. All the water we normally drink – from taps, from bottles, from the garden hose – contains impurities which affect a property of water called tonicity. This is the ability of a solution to draw or repel water from ajacent solutions when separated by a membrane. Solutions t…

>I'm told by people that you can drink out of a swamp or mud puddle with a good filter. "Good filter" is a relative term. Maybe you could do it if you "filtered" the water with a $10M reverse osmosis membrane? The filters I buy all say "do not use with unsafe water" or some similar phrase.

Filters for camping/outdoor usage are less than $100 and most of them are explicitly sold as suitable for use with dirty water. You get a disclaimer that they'll be slower and need to be replaced more often when used on dirty/cloudy water, and sometimes they also advise a chemical or UV treatment be used post-filtering if there are concerns about viruses.

There is a specific danger associated with the water going up your nose. Things that go up your nose have better access to the blood brain barrier. Don't snort unboiled water kids.

Source? 'access to the blood brain barrier' sounds odd. You make it sound like the BBB magically starts in the nostrils and is somehow weak there. That's not how the BBB works. Sure, your nostrils are closer to your brain than, say, your teeth, but not by much.

The hot water in your water tank may contain an excess of salt deposits, leeched metals, and rusts that you don't want to consume. Cold water has less solubility of most substances than hot water and it spends less time sitting in a hot container of those substances. Therefore, use the cold water to make hot water on your stove and regularly clean the kettle: https://www.reddit.com/r/ThingsCutInHalfPorn/comments/7uu0…

> The hot water in your water tank may contain an excess of salt deposits This is clearly impossible due to conservation of mass, unless you're claiming that the water heater is so hot that it causes nuclear reactions in the water.
