DEEP REVIEW

RKIN·Clean Air & Water

U1-W 4-in-1 Countertop RO

Reverse osmosis is the most thorough consumer water treatment you can buy, and it normally means an under-sink install. The RKIN U1-W puts a full 5-stage RO system on the counter: fill the 1-gallon tank, and it dispenses purified water hot or cold with no plumbing at all.
