Brand: LG
Stainless-steel tank and self-sterilising UV care
Our editorial score
Outstanding — a top pick in its class
Hygiene-focused buyers, humid coastal cities, and anyone who has ever opened a purifier tank and been unpleasantly surprised.
Almost every purifier sold in India stores purified water in a sealed plastic tank at room temperature for hours at a time. In a Chennai or Kochi summer, that is an excellent environment for biofilm, and it is the failure mode nobody markets against. LG's answer is the right one on both counts: a stainless-steel tank that resists colonisation, and an automatic UV cycle that sterilises the tank and the outlet tap every couple of hours whether you remember to think about it or not.
That is worth paying for, particularly in humid coastal cities and particularly if there are children or elderly family members in the house. What you are not getting is a high-TDS specialist — for 1,500 ppm borewell water the AO Smith Z9 is the better machine — or a compact one, because this is a counter-top appliance with a real footprint.
Every condition below is derived from this product's published specifications and from how it compares with the water purifiers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
Your supply runs above 2,000 ppm TDS
The membrane is rated to 2,000 ppm. Feed it more and it will not fail dramatically — it will die early and quietly, and you will be buying membranes annually. Check your worst-season reading, not your average one.
Purifiers for high-TDS supply →Water wastage matters to you
The brand does not publish a recovery figure, so there is no way to know how many litres go to drain per litre purified. Only 2 of the 26 water purifiers we track publish this at all.
High-recovery purifiers →Low running cost is a priority
Consumables and routine service run about ₹4,400 a year, which is in the most expensive quarter of the water purifiers we track. Over five years that puts total ownership near ₹53,990.
Sort the database by five-year cost →Fair transparency. This is separate from our review score above — it measures how well documented, how supportable and how expensive to own this water purifier is, scored on 6 of 7 axes by formula, with no manual override. See the methodology.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
LG's purifiers are the premium engineering choice: stainless-steel tanks instead of plastic, dual-protection UV that sterilises the tank and the tap, and a self-sterilising cycle. If tank hygiene is your concern — and with Indian ambient temperatures it should be — this is the answer. In refrigerators, LG is the most consistently recommended brand in India: the Smart Inverter Compressor carries a ten-year warranty, holds temperature within a tighter band than reciprocating designs, and runs quietly enough to be unobtrusive in an open-plan flat.
