Water purifier buying in India can get confusing because every brand talks about RO, UV, UF, minerals, copper, alkaline, and water saving. But the real decision is simpler: what is your water source, how high is the TDS, how many people are at home, and how much service support do you want after buying?
Best water purifier in India
For most Indian homes using tanker, borewell, or mixed municipal water, we would start with an RO+UV or RO+UV+UF purifier from a brand with reliable service in your city. If your water TDS is low and mostly municipal, you may not need a full RO purifier at all.
RaviSelect verdict
Editor’s note: Water purifier suitability depends heavily on local water quality. Before buying, verify input TDS, water source, service availability, annual maintenance cost, filter replacement cost, storage capacity, and whether your home actually needs RO.

We are not picking only by big purification claims.
Many water purifiers advertise many layers of purification, but the practical buying decision is still about water source, TDS level, service network, filter cost, storage capacity, and whether RO is actually needed in your home.
For this shortlist, we looked at purification type, storage capacity, brand confidence, service practicality, family fit, and whether the purifier makes sense for common Indian water situations. We have not lab-tested these water purifiers yet, so this is an editorial shortlist based on specifications, official pages, and practical use-case fit.
What we checked before shortlisting water purifiers
Why these water purifier picks made the list
Pureit Eco Water Saver RO+UV+MF
This is the purifier we would check first for many Indian homes because it balances the things that matter: RO+UV+MF purification, 10L storage, and a water-saving focus compared with basic RO purifiers.
The bigger tank helps if your family uses purified water frequently through the day. The main thing to check is service support and filter cost in your area. If Pureit service is strong near you, this is one of the easier recommendations to start with.
Pros
- Large 10L storage tank
- RO+UV+MF purification setup
- Water-saving positioning
Cons
- RO may be unnecessary for low-TDS water
- Filter cost should be checked
- Service quality can vary by city
Bottom line: Buy this if you want a safe all-round RO water purifier for mixed water sources. Skip it if your home has low-TDS municipal water and does not need RO.
Aquaguard Sure Delight NXT RO+UV+UF
Aquaguard Sure Delight NXT is a practical pick for buyers who want a known service-focused brand without jumping into a very expensive purifier. The RO+UV+UF version keeps the feature set sensible for mixed water sources.
The 6L storage is fine for smaller families, but larger homes may want a bigger tank. The biggest reason to shortlist it is simple: Aquaguard service reach is often the comfort factor buyers look for.
Bottom line: Choose this if you want a mainstream RO purifier with Aquaguard confidence. Skip it if you want a larger storage tank.
KENT Supreme RO+UF+TDS Control
KENT Supreme makes sense for buyers who specifically want RO purification with TDS control and KENT’s familiar mineral RO positioning. It is meant for brackish, tap, and municipal water supply situations.
The trade-off is ongoing cost. RO purifiers need filters, membranes, and regular service. If your local KENT service is good, it can be a safe pick. If service is weak in your area, check alternatives first.
Bottom line: Buy this if you want a KENT RO purifier with TDS control. Skip it if annual maintenance cost is your biggest concern.
AO Smith Z9 RO+SCMT
AO Smith Z9 is the premium pick because it adds hot water convenience to a full RO purifier. The 9.2L normal tank plus 0.8L hot tank can be useful for homes that want hot drinking water or quick warm water access.
The main limitation is price. You should buy this only if the hot water feature is genuinely useful for your family. If you only need normal purified water, Pureit, Aquaguard, or KENT may be more sensible.
Bottom line: Choose this if you want a premium RO purifier with hot water dispensing. Skip it if you want the best value under a tight budget.
What to know before buying a water purifier
First, test your water TDS. If TDS is high or your water comes from borewell or tanker supply, an RO purifier usually makes more sense. If TDS is low and water is already treated municipal supply, UV or UV+UF may be enough.
Second, check service availability before price. A cheaper purifier becomes frustrating if filters are unavailable or service takes too long. Water purifier ownership is not a one-time purchase; it has annual maintenance costs.
Third, do not overbuy technology. Copper, alkaline, mineral, and smart features may sound attractive, but the basics matter more: right purification type, clean storage tank, reliable alerts, and easy filter replacement.
RO is not always the right answer
An RO purifier can be useful for high-TDS water, but it also wastes some water and removes minerals unless the purifier has a mineral/TDS management system. For low-TDS municipal water, buying RO only because it sounds premium can be unnecessary.

Water purifier FAQs
Which water purifier is best for Indian homes?
For many Indian homes with mixed water sources, an RO+UV or RO+UV+UF purifier is a safer starting point. But if your municipal water has low TDS, a UV or UV+UF purifier may be enough.
Is RO water purifier always needed?
No. RO is mainly useful for high-TDS water, borewell water, tanker water, or hard water. For low-TDS municipal water, RO may be unnecessary.
What TDS level needs RO purifier?
There is no single rule for every home, but RO is generally considered when TDS is high or taste/hardness is a problem. Test your home water before buying.
What is more important: RO, UV, or UF?
RO reduces dissolved impurities, UV helps disinfect microorganisms, and UF adds physical filtration. The right combination depends on your water source and TDS level.
