In an Indian kitchen, purified water goes into far more than the drinking glass. It’s the water for chai, for soaking dal and rice, for kneading atta and for nimbu pani on a hot afternoon. A good purifier makes that water safe and pleasant to drink, without wasting more water than it needs to.
The most important decision isn’t the brand: it’s whether you need RO at all. That depends on your water source and its TDS (total dissolved solids). We compared the specifications, service plans and recurring buyer feedback of popular purifiers on Amazon.in from KENT, Aquaguard, Pureit and Livpure, and chose five for Indian homes, including one for low-TDS municipal water that doesn’t need RO.
Quick answer: the best water purifiers in India right now
The best water purifier for most homes is the KENT Grand RO: RO, UF and UV in the storage tank, a TDS controller to keep some natural minerals, a 7.5 litre tank, 20 litres per hour output and a 4.4 out of 5 rating from more than 8,000 buyers. Here’s the full shortlist:
- KENT Grand RO: best overall for borewell, tanker and municipal water.
- Aquaguard Sure Delight NXT RO+UV: best for hassle-free service.
- Pureit Wave Plus RO + Mineral + UV: best for saving water.
- Livpure GLO PRO++ RO+UV+UF: best budget RO purifier.
- KENT Ultra Storage UV: best for low-TDS municipal water (no RO).
How we chose these water purifiers
Full transparency first: this is a research-based guide, not a hands-on test. We didn’t run lab tests on water quality. We compared each purifier’s specifications on its Amazon.in listing, the warranty and service plans available in India, and the recurring themes in buyer feedback, including the complaints. Every model was in stock on Amazon.in when we checked in November 2026. You can read how we work in how we review kitchen products.
One honest note: with water purifiers, after-sales service matters as much as the machine, because filters and membranes need regular replacing. We leaned towards brands with wide service networks and clear service plans. Purification claims on each listing are the manufacturer’s own.
First, check your water: do you need RO?
RO (reverse osmosis) removes dissolved salts and is needed when your water’s TDS is high, which is common with borewell and tanker water. If your supply is municipal water with low TDS, a UV or UF purifier is usually enough, and it doesn’t waste water like RO does. For reference, India’s drinking water standard (BIS IS 10500) sets 500 mg/L as the acceptable limit for TDS.
- Borewell or tanker water, or high TDS: choose RO, ideally with UV or UF and a TDS or mineral controller.
- Municipal water with low TDS: a UV or UV+UF purifier is usually enough.
- Not sure? Ask the brand’s technician to test your TDS before installation. Most do it free, or you can buy a simple TDS meter.

The KENT Ultra Storage uses inline UV plus UF instead, so it doesn’t reject any water, and its output is fast at up to 60 litres per hour. The 8 litre tank is the largest in this guide, it’s wall mountable, and it costs far less than RO models. It’s rated 4.0 out of 5 by more than 4,500 buyers.

Who should skip it: Skip it if your water is from a borewell or tanker, or tastes salty. You need RO.
Water purifier buying guide: what really matters
RO, UV and UF explained
- RO (reverse osmosis): pushes water through a fine membrane to remove dissolved salts and many chemicals. Needed for high-TDS water, but it sends some water to waste.
- UV (ultraviolet): uses UV light to disinfect bacteria and viruses. It doesn’t remove dissolved salts and needs electricity.
- UF (ultrafiltration): a membrane that removes bacteria, cysts and suspended particles. It doesn’t remove dissolved salts.
Storage and output
A 6 to 8 litre tank suits most families and keeps water available during power cuts. Output of 15 to 20 litres per hour is plenty for drinking and cooking.
Running costs and service
Filters and membranes need replacing, typically every year or so depending on your water and usage. Ask about the price of a service plan or annual maintenance contract before you buy, and choose a brand with a service centre in your city.
Reusing RO reject water
RO reject water is high in dissolved salts, so don’t drink it, but you can collect it to mop floors, wash vessels or flush toilets instead of letting it go down the drain.
Using purified water in the kitchen? Siddhi’s guide to soaking rice, dal and sabudana and her nimbu shikanji concentrate are good places to start.
Frequently asked questions
Which is the best water purifier in India?
For most homes on borewell, tanker or high-TDS water, the KENT Grand RO is a well-reviewed all-rounder with RO, UF, UV in the tank and TDS control. For low-TDS municipal water, a UV purifier like the KENT Ultra Storage is usually enough.
Do I need an RO water purifier?
You need RO if your water has high TDS, which is common with borewell and tanker water. Low-TDS municipal water usually only needs UV or UF purification. Get your water’s TDS tested before you buy.
What TDS level is acceptable for drinking water?
India’s drinking water standard, BIS IS 10500, sets 500 mg/L as the acceptable limit for TDS. Water above that usually needs RO purification.
How often should I service my water purifier?
Follow the brand’s schedule, which is often every 6 to 12 months depending on your water quality and usage. Filters and membranes are replaced as needed during service.
Does an RO purifier waste water?
Yes, all RO purifiers send some water to waste as they remove dissolved salts. Water-saving models reduce this, and you can reuse reject water for cleaning.
Our verdict: which water purifier should you buy?
Check your water first. For borewell, tanker or high-TDS water, buy the KENT Grand RO. Want service taken care of? The Aquaguard Sure Delight NXT includes a service plan. Short of water? The Pureit Wave Plus wastes less. On a budget, the Livpure GLO PRO++ covers the basics, and for low-TDS municipal water, the KENT Ultra Storage UV is all you need.
