Best Water Purifiers Under ₹10,000 in Lucknow (2026)

₹10,000 is the threshold at which genuine reverse osmosis becomes possible — below it you are buying microbiological safety only. The question this page answers is whether that budget is enough for Lucknow specifically, and the answer depends entirely on the 350-850 ppm that comes out of local taps.

Lucknow needs RO, so at this budget you are looking at the two models that deliver a real membrane, a real UV lamp and a UF stage under ₹10,000: the Livpure Glo Pro++ at around ₹8,990 and the Aquasure Delight at around ₹9,490. Both will handle Lucknow's supply. Verify any other sub-₹10,000 listing explicitly names an RO membrane — at this price point "RO" is frequently used loosely for what is a carbon filter.

The compromise you are making is the TDS controller, which neither budget model includes. At Lucknow's TDS that matters more than you might expect, because output can come out flatter than you would like. If you can stretch to ₹13,000-₹15,000, the Livpure Zinger Copper and Faber Galaxy Pro Plus add it.

Every major brand services Lucknow directly, so you can choose on specification and price here rather than on who has an engineer nearby — which is a luxury buyers in smaller cities do not have.
