Best water purifier in India — RO, UV or UF for your water

Match the purifier technology to your actual water, then compare live prices on the exact model.

1. Test your water before buying

The right purifier depends on your water, not the brand. Get a TDS check — many stores and technicians do it free. Low TDS, municipal or borewell water that is already soft needs only UV or UF. High TDS, salty or bitter water needs RO.

2. RO, UV, UF and what each does

UV kills germs but leaves dissolved salts and chemicals. UF filters out particles and cysts. RO strips salts, heavy metals and most dissolved solids, but wastes some water and needs pressure. Many Indian homes need RO+UV, and RO+UV+UF if the water is very hard.

3. Storage tank size for your family

A 6–8 litre tank is fine for two or three people. Families of five or more, or homes with frequent guests, should look at 9–12 litres. Non-tank models purify on demand but need good inlet pressure to keep up.

4. Filter cost beats purchase price

The machine is a one-time cost; filters are yearly. Compare the price and local availability of sediment, carbon and RO membranes before you choose. A cheaper purifier with costly or hard-to-find cartridges ends up more expensive.

5. Hard water shortens RO life

If your area has heavy scale, add a water softener or a pre-filter, and descale as the manual says. Without it, the RO membrane chokes early and you replace it far sooner than the warranty suggests.

6. Installation, mounting and power

Check wall-mount space, inlet and drain points, and whether the model needs electricity. Some RO+UV models work without power for the UV stage but not for RO. Ask whether installation and the first cartridge are included.

7. Compare the exact model, not the brand

Aquaguard, Kent, Pureit, Livpure, Havells, Eureka Forbes and Blue Star each sell many similar models with different tank sizes and stages. Prices differ a lot between Amazon, Flipkart, the brand's own site and local dealers — compare the same model number.

Frequently asked questions

Do I need RO or is UV enough?

Check your water's TDS. Below about 200 ppm, UV or UF is enough and keeps minerals. Above 500 ppm, or if the water tastes salty, use RO.

Is RO water bad because it removes minerals?

RO water has fewer minerals, but most people get minerals from food. If your TDS is low, choose a purifier with a mineral or TDS-control stage instead of RO alone.

How often do filters need changing?

Sediment and carbon filters usually every 3–6 months, RO membranes once a year or two. Cost and availability of replacements matter more than the purchase price.
