Water TDS safe limits?

Can't you get used to the higher concentration of salt and not notice an increase in salinity?

Maybe I'm just gullible then. I have a ZeroWater Pitcher with a TDS meter. My water out of facet is 260 TDS and after running through the ZeroWater filter..it reads 0..No electric energy expelled

That would be gullible ... kinda. Those are ion-exchange filters. The are not so much as removing the salt as replacing it with a different salt. In most cases it is for softening the water for washing purposes. Exchanging 'hard' Magnesium and Calcium for the 'soft' sodium (and potassium?).

I don't think it is of any benefit for drinking ... I think even less healthy.

Lowering from a quite pure 250TDS to zero is nothing compared to desalination from 30,000TDS to 250TDS.

Not sure how they get the 0TDS with so much salt in the water. Might be some other use of the term TDS.

Check several brands of mineral water bottles,they range from 100 till 1400 PPM
Typically,Evian is around 500.The label round the bottle tells you all needed infos : TDS (total dissolved solids) tells you the salinity,mostly in Mg/l (Parts Per Million)
Chloride and Natrium +some other

Distilled water is an active absorber and when it comes into contact with air, it absorbs carbon dioxide, making it acidic. The more distilled water a person drinks, the higher the body acidity becomes.
According to the U.S. Environmental Protection Agency, "Distilled water, being essentially mineral-free, is very aggressive, in that it tends to dissolve substances with which it is in contact. Notably, carbon dioxide from the air is rapidly absorbed, making the water acidic and even more aggressive. Many metals are dissolved by distilled water."

Sheesh.... Glad I don't drink the stuff... sounds awful..

In France I really love Vichy mineral water , its has a TDS of about 1100. Very nice to drink, but it does load up your daily sodium levels

This is a crock. First, I'm a molecular biologist by education. I'm also a long time reef aquarist. I know water. Second, I've done extensive tests of rainwater for tds. It runs from 2 to 10ppm, generally. We can all agree that rainwater is safe to drink, right? Right? I thought so.

As previously noted, you can find all sorts of stuff on the Internet about how bad pure/ro/distiller water is for you. The just want to sell you something or theynarenjust repeating what the heard/read somewhere else. Bottled water companies add in minerals to improve taste.
