RO/DI Water Safe To Use

[Rogue951]

DI is not used for standard drinking water.
If you look at any residential home purification system (anything at rona, home depot) You'll see none of them use DI.

Stick with the earlier advise. Put a T after the RO and use just RO for your baby.
I use RO for my coffee just to reduce the likelyhood of calcium build up in the boiler. (I use a Keurig K cup machine)

That said, I would not use it as the main source of water due to the lack of mineral and trace element. If someone drink too much of this pure water then this can lead to water poisoning. We do need mineral salts in our drinking water to compensate for what we lose in sweat.
