Purifier Guidance for Every Indian City

There is no single correct water purifier for India, and treating the country as one market is how people end up with the wrong machine. Municipal supply in Kochi runs around 100-400 ppm TDS; groundwater in Barmer can exceed 2,200 ppm. The first needs UV, the second needs a brackish-water RO. Same country, completely different purchases.

The same applies to air. Delhi and Ghaziabad need year-round HEPA capacity sized well above the box rating. Aizawl, Gangtok and Port Blair genuinely do not — there, the reasons to buy are specific ones like allergies or a traffic-facing window.

Pick your city below for local guidance.

Highest TDS cities

These need brackish-water-rated membranes and a lab analysis before purchase.

Lowest TDS cities

Here a UV+UF purifier is the technically correct choice — RO wastes water and strips minerals for no benefit.

Highest average AQI

Size up two room classes, prioritise carbon depth, and buy one purifier per bedroom.
