By budget
₹4,000 is one of the most-searched water purifier budgets in India. 9 of the 141 purifiers verified on this site fall below it, from ₹1,449 to ₹3,449, with a median of ₹2,290.
Not one of these 9 is an RO purifier. Below ₹4,000 the category is gravity and UV units, which kill bacteria and viruses but remove no dissolved solids at all. If your supply is borewell, tanker or hard municipal water, nothing on this page will fix it — you need RO, and that starts higher up.
3 brands are represented: KENT 7, Pureit 1, Brita 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.
Filter by price, brand and feature, or sort by price and running cost. Tick Compare on any two to put their specs side by side.

An RO stage is what removes dissolved solids. UV and UF kill microbes and remove none, so the right choice depends on your TDS, not your budget.
Filters and membranes cost more over five years than most of these units cost to buy. Every product shows an estimated annual figure.
Every price here was read from the brand's own store. Nothing is taken from a marketplace listing or an SEO title.
