In India, water quality varies wildly — from municipal tap to borewell to tanker water. A reliable RO water purifier isn't a luxury; it's a necessity for your family's health. Modern RO purifiers have evolved dramatically: they now come with smart IoT monitoring, multi-stage filtration with copper and alkaline enrichment, touch-screen dispensing, and filters that last up to 2 years without a single service call.
We evaluated purifiers across key parameters: filtration stages, water wastage ratio, service costs, smart features, and after-sales reliability. Whether you're upgrading from an older unit or buying your first purifier, here are our top picks for 2026.
Native M2 Pro by Urban Company
Editor's Review & Buying Advice
The Native M2 Pro by Urban Company has been a game-changer in the Indian RO market. Its headline feature is a 2-year, zero-service filter life — you literally don't need a single AMC or technician visit for 2 full years, saving up to ₹20,000 over 8 years of ownership. The 10-stage filtration with ISI-certified RO + UV eliminates viruses, bacteria, and heavy metals, then remineralizes with calcium, magnesium, copper, and alkaline — no MTDS mixing or RO bypassing. The touch-screen dispensing with preset modes (glass, bottle, free-flow) and built-in battery backup for power outages is genuinely premium. Real-time TDS monitoring through the Urban Company app provides peace of mind at every glass.
Pros
- 2-year service-free filters — industry leading

- Touch-screen dispensing with preset volume modes

- 100% RO processing — no MTDS mixing shortcuts
- 2-year unconditional warranty on all parts
Cons
- Premium price point (₹19,499)

Tech-savvy families who want a premium, low-maintenance RO with smart monitoring and zero service hassle. If you hate dealing with AMC calls and technician visits, this is your purifier.

HUL Pureit Eco Water Saver Mineral RO+UV+MF
Editor's Review & Buying Advice
If water wastage is your primary concern, the HUL Pureit Eco Water Saver is the clear winner. Traditional RO purifiers waste 60–75% of input water. The Eco Water Saver claims up to 60% water savings compared to ordinary ROs, which is a massive environmental and cost benefit, especially in areas with water scarcity. The mineral enrichment cartridge adds back calcium and magnesium to give purified water a natural, sweet taste. HUL's after-sales network is strong across Indian metros, and the 10-litre storage capacity is the largest among our picks.
Pros
- Up to 60% less water wastage — best eco-friendly RO
- 10-litre storage — largest capacity in this guide
- Mineral enrichment restores calcium & magnesium
- Affordable price point with good brand backing
Cons
- No smart features or app connectivity
- Filter replacement required every 6–12 months
- Build quality feels more plastic-heavy than premium models
Who Should Buy This
Eco-conscious families in water-scarce areas who want to minimize wastage while still getting reliable RO purification. Also great for large families needing 10L storage capacity.
Which RO Water Purifier should you choose?
For most families, the Native M2 Pro by Urban Company is our top recommendation — its 2-year zero-service filters, smart IoT monitoring, and premium touch-screen dispensing make it the most advanced and hassle-free purifier on the market. If you prioritize nationwide service availability and brand trust, the Kent Supreme Star remains the gold standard. And if water conservation is your priority, the HUL Pureit Eco Water Saver wastes far less water than any competitor, making it ideal for eco-conscious families or areas with water scarcity.
Pro Tip: Before buying, test your home water's TDS level with a simple TDS meter (available for ₹150–300 on Amazon). If your TDS is below 300 PPM, you may only need a UV purifier instead of RO.
