₹12,000 is one of the most-searched water purifier budgets in India. 32 of the 141 purifiers verified on this site fall below it, from ₹1,449 to ₹11,599, with a median of ₹8,349.
Only 10 of the 32 (31%) carry an RO stage. That matters more than any other spec here: UV and UF kill microbes but remove no dissolved solids, so on borewell or tanker supply a non-RO purifier will not make the water drinkable. Check your TDS before choosing from this page.
7 brands are represented: KENT 16, Faber 8, Livpure 4, Pureit 1, Brita 1, ZeroWater 1. Every price is the manufacturer's own, read from the brand's own store — never from a marketplace listing or a price-comparison page.
Remember that the purchase price is the smaller half of the decision. An RO purifier costs roughly ₹3,000 a year in filters and membrane; a UV or UF unit about ₹1,200; a gravity unit about ₹600. Those are category estimates and are shown on every product below.
