The checklist

  • Technology: RO is needed when TDS is above 300 ppm; for municipal water below that, UV plus UF keeps useful minerals.
  • Storage: 7 to 10 litres covers a family during power cuts.
  • Running costs: check filter and membrane prices and whether an annual maintenance plan is included.

Set your budget

The water purifiers we researched sell for ₹6,999 to ₹24,000. Decide how you will use it first; the priciest model is often a skip for everyday needs.

India-specific tip

Test your water TDS first (many sellers do it free at installation): RO on low-TDS water wastes water and removes minerals, so choose the technology your water actually needs.

Typically every 6 to 12 months, depending on water quality and use. Most brands remind you or offer service plans.

Before you buy a water purifier: the essentials

Buying a water purifier is easier once you know which three or four specs actually change your experience and which are just marketing. This guide covers exactly that for water purifiers sold in India, plus the budget to plan for, the local quirks to watch and the models we would buy today.

What to spend

The water purifiers we checked sell for ₹6,999 to ₹24,000. Below that range you usually lose durability or a key feature; above it, make sure you will really use the extras.

Prices on Amazon.in move in a pattern. The deepest cuts land in the Great Indian Festival (around Navratri and Diwali), Prime Day in July and the Republic Day sale in January, usually with extra bank-card discounts and no-cost EMI. Judge a deal against the usual price we show, never against the MRP.

Order from Amazon itself or the brand's own storefront so the India warranty applies, keep the GST invoice and register the product with the brand straight away. For ACs, geysers, chimneys and purifiers, ask whether installation and the demo visit are free before you pay.
