Reverse-osmosis purified water, done properly

How it is purified
Deep underground water, reverse osmosis, UV sterilisation, then minerals added back to a set profile. Purified in Pakistan and conforming to PS 4639 under Punjab Food Authority licence.
Why reverse osmosis matters
Reverse osmosis strips dissolved solids, heavy metals and contaminants at a molecular level. Koh Waters then adds minerals back so the water is pure but not flat — a balanced 7.0 pH and 210 mg/L total minerals.
