Water Purifier Buying Guides for Indian Homes

Choosing a water purifier depends on your water source, TDS level, family size, and service needs. Compare RO, UV, and UF options before you buy.

Water purification for Indian homes

India has diverse water quality. Borewell water can be high in TDS. Municipal supply may contain chlorine. Tanker water is unpredictable. Shopaluru helps you pick the right technology for your source.

RO: Removes dissolved salts — best for high TDS borewell water
UV: Kills bacteria and viruses — good for low TDS water
UF: Removes suspended particles and some bacteria
RO+UV/UF: Common combination for mixed or uncertain sources
