How benchmarksutra rates water purifiers: maker-stated specs and Indian prices only, nothing guessed.
Quick Verdict
The benchmarksutra Water Purifier Score rates 4 water purifiers sold in India. Every spec comes from the maker's own product page, and every price from an Indian retailer's listing. We never use test results from other sites, and we never fill a gap with a guess.
Researched, not hands-on tested. Scores use only the specifications on each maker's own product page (checked 14 November 2026) and prices at Indian retailers (checked 14 November 2026). We did not test these water purifiers ourselves. How the benchmarksutra Water Purifier Score works.
What we rate
Storage tank. Storage tank in litres, as the maker states it. 10 litres rates 100.
Purification rate. Purification rate in litres per hour, as the maker states it. 20 L/h rates 100.
Water recovery. Water recovery (share of input water that comes out as drinking water) the maker states: 20% rates 0, 70% or more rates 100. Where not stated, the row is left out.
Input TDS handled. Highest input TDS the maker says the purifier handles, in ppm. 2,000 ppm rates 100. Match this to your tap water; RO is meant for high-TDS water.
Price. Lowest price we found, against the cheapest purifier of the same type.
Buyer profiles
What we checked
We read each maker's own product page for purification technology, storage tank, purification rate, water recovery and the input TDS range. Retail listings are used only for the price. Where a maker leaves something out, that row is left out and the weights re-spread. A purifier is ranked only if its maker states at least 3 of the 5 rated specs.
What we do not rate, and what we do not claim
We do not test water and we make no health claims. Germ, virus or metal removal claims are the maker's own; check that the model carries the BIS mark for its standard and get your tap water TDS tested before choosing RO. RO is not needed for low-TDS water (for example, most piped municipal supply under about 300 ppm), and it wastes water.
