eli5: Why can’t you drink Demineralised Water?

1.10K viewsChemistryOther

At my local hardware store they sell something called “Demineralised Water High Purity” and on the back of the packaging it says something like, “If consumed, rinse out mouth immediately with clean water.”

Why is it dangerous if it’s cleaner water?

Honest question related to this topic:

My tap water has lead in it (old pipes), so I installed a reverse osmosis system under the sink for obvious reasons. It came with a system for remineralizing the water, and alkalizing it, but the connection kept leaking, so I just hooked it up directly to the dispenser, essentially making it so the water we drink comes directly from the reverse osmosis.

Thoughts?
