By product type
We list 7 whole-house water filters from 1 brand, priced ₹7,195 to ₹94,995, every one from the brand's own Indian store. The highest-scoring is the The Water Science MainLine Filter (10 inch, 1 bath, 1-stage) at ₹7,195.
A whole-house (point-of-entry) filter sits on the main inlet or after the overhead tank and filters every litre that enters the home — sediment, rust and silt, and on two-stage units some hardness. It protects plumbing, geysers, washing machines and bathroom fittings. It does not make water safe to drink, so it complements rather than replaces a drinking-water purifier.
Scores are calculated from each product's published specifications and price within its own product family; nobody at BestPurifier has tested these products.
