Purification
Purification: 100% RO + SCMT (Silver Shield) + Copper Fortified Mineraliser + Alkaline. RO (reverse osmosis) removes dissolved salts, which matters when your water's TDS is high (borewell or tanker water); for low-TDS municipal water it is often not needed. It also has copper/zinc infusion and an alkaline stage, as described by A. O. Smith. Stated maximum input TDS: 2,000 ppm. Test your water (a TDS meter costs little) before choosing.
Capacity and water use
The tank holds 5 litres. It purifies about 15 litres an hour, as stated. Stated water recovery is 40%: for every 100 litres that go in, about 40 litres come out purified and 60 litres go to the drain. Rated power: 48 W. Installation: wall or counter top. Tank material: Food safe, non-toxic, engineering grade plastics.
Running and ownership
Warranty: 1 year (Peace of Mind with 1 year comprehensive warranty (includes RO membrane and filters)). Filters and the RO membrane are a running cost; ask the brand for the annual maintenance plan price before you buy.
