We list 90 water treatment products from 6 brands — 11 water softeners, 14 shower filters, 7 whole-house filters, 16 meters and monitors and 39 RO spare parts — priced ₹374 to ₹1,26,000. Every one is listed from the brand's own Indian store (The Water Science, KENT, Livpure, HM Digital, Konvio and Crompton), with the brand's price, photo and stock on the date shown.

Start with a test, not a product. A TDS meter tells you whether your drinking water needs RO; a hardness test tells you whether a softener is worth it; yellow-brown stains mean iron, and muddy borewell or tanker water needs a sand or sediment filter first. Buy only the stages your water actually needs.

Know what each product can and cannot do. Only an ion-exchange softener truly softens water for the whole house. Shower, tap and washing-machine filters reduce hard-water effects at a single outlet and need regular cartridge changes. And none of these makes water safe to drink — keep a drinking-water purifier for that.

How we rank: scores are calculated within each product type from published specifications — capacity, stages, automatic regeneration, what a meter measures — plus price and the brand's support in India. Nobody at BestPurifier has tested these products.

    Frequently asked questions

    How do I treat hard water at home in India?
    An ion-exchange water softener on the main supply is the only complete fix. For less money, a bathroom softener treats one bathroom, and shower, tap and washing-machine filters reduce hard-water effects at single outlets. Test hardness first.
    Do shower filters work for hard water?
    Partly. They cut chlorine and sediment well and reduce some hard-water effects on hair and skin, but they are not softeners and the cartridge must be replaced every few months.
    Which TDS meter is best?
    Any calibrated handheld TDS meter answers the key questions — whether your supply needs RO and whether your RO still works. Waterproof multi-parameter meters add pH and temperature; in-line monitors show RO output continuously.
    How often should an RO membrane be replaced?
    Typically every 1-3 years, depending on input TDS and on changing the sediment and carbon pre-filters on time. A steady rise in output TDS is the sign.
    How do I treat borewell water?
    In stages, based on a test: a sand filter for turbidity, an iron removal filter if water stains yellow-brown, a sediment or mainline filter, and a softener if hard. Drinking water still needs an RO purifier.
