Depends on the purity of demineralisation. DM water usually contains 1-10m/L (ppm). Generally safe unless you’re exclusively drinking it
100% demineralised will definitely cause massive harm though, because it’s so hypotonic. Your cells will start absorbing water. This disturbs the balance of electrolytes (electrically conductive ions) in your body. This is most seriously a problem in the brain, where water poisoning can lead to brain damage, coma and even death.
