Why Choosing the Right Water Purifier Brand Matters
Most Indian households depend on groundwater drawn from aquifers, and a large share of the country’s population relies on it for both drinking and farming. Untreated groundwater often carries dissolved salts, heavy metals, and microbial contamination, which is exactly why a good water purifier isn’t optional in most parts of the country — it’s a daily health necessity. The Indian water purifier market has grown steadily over the past decade, with RO (reverse osmosis) purifiers now dominating sales in regions with high TDS (total dissolved solids) water, alongside UV and gravity-based purifiers in areas with lower TDS but higher microbial risk.
To make things easier, we’ve put together the five water purifier brands most Indian households actually buy from — covering their history, technology, and where each one genuinely stands out. One important update since this space was last reviewed: HUL sold its Pureit water purification business to A. O. Smith in November 2024, so Pureit is no longer a Hindustan Unilever brand — we’ve corrected that below. If your home also needs reliable hot water, it’s worth pairing your purifier with one of the best geyser brands in India.

💧 List of 5 Best Water Purifier Brands in India: Full Profiles
1. Eureka Forbes (Aquaguard) — Best Overall
★ Key Features
- 40+ Years in the Market: One of India’s oldest dedicated water purifier brands, with a customer base built up over four decades.
- Aquaguard & AquaSure Lines: Aquaguard is the premium, direct-sales line; AquaSure is the value-focused retail line — both under Eureka Forbes.
- Global Presence: Operates in dozens of countries beyond India through its international network.
- Large Service Network: Thousands of trained technicians and service centres, making after-sales support easier to access almost anywhere.

Eureka Forbes — Best for Nationwide Reliability
Eureka Forbes earns the top spot mainly on reach and trust — few brands can match its service network size or the sheer breadth of purifier types it offers for different water conditions. If reliable after-sales support matters as much as the purifier itself, this is usually the safest starting point.
2. KENT RO Systems — Best Advanced Technology
★ Key Features
- Pioneered RO in India: Dr. Mahesh Gupta founded KENT in 1999 after developing one of India’s first domestic RO water purifiers, and the brand has stayed focused on RO technology since.
- Multi-Stage Purification: Many models combine RO, UF, UV, alkaline enhancement, copper infusion, and TDS control in a single unit.
- Zero Water Wastage Tech: Select KENT models are built to recover more of the input water than standard RO systems, reducing waste.
- Internationally Certified: Products are certified by NSF and WQA in the United States, a mark not every Indian brand carries.

✔ Pros
- Deep RO technology expertise and international certification
- Retains essential minerals while removing dissolved impurities
- IoT models offer real-time monitoring and alerts
- Extended warranty options on flagship models
❌ Cons
- Advanced models sit at a higher price point
- Feature-heavy units can mean more maintenance touchpoints
KENT — Best for Purification Technology
KENT built its reputation on RO expertise, and it shows in how deep its technology stack goes — multiple purification stages, mineral retention, and now IoT connectivity on top-tier models. If you want the most technically advanced purifier available in India, KENT is usually the brand to compare against.
3. Pureit (by A. O. Smith) — Best Budget & Non-Electric
★ Key Features
- Now Owned by A. O. Smith: A. O. Smith, a global water heater and water-treatment company, acquired Pureit from HUL for roughly $120 million in a deal that closed in November 2024.
- Non-Electric Purifiers: The Pureit Classic range uses gravity-based purification with no electricity needed — useful in areas with unreliable power.
- 7-Stage Purification: Electric RO/UV models use multi-stage filtration designed to handle TDS levels up to 2000 PPM.
- Copper Charge Technology: Newer models infuse purified water with copper for its traditional health associations.
- Established Track Record: First launched in Chennai in 2004 and expanded nationwide by 2008, giving it two decades of presence in Indian households.
✔ Pros
- Genuinely low-cost, electricity-free options available
- Handles high-TDS water well on RO/UV models
- Two decades of brand presence and consumer familiarity
- Backed by A. O. Smith’s global water-technology expertise going forward
❌ Cons
- Brand ownership change (HUL → A. O. Smith) may cause some transition confusion for existing customers
- Non-electric models can’t match RO purifiers on very high-TDS water
Pureit — Best for Budget-Conscious & Power-Cut-Prone Homes
Pureit’s non-electric gravity purifiers remain one of the few genuinely low-cost, no-power options on the Indian market, which still matters in areas with frequent outages. With A. O. Smith now behind the brand instead of HUL, expect continuity in the existing lineup along with likely investment in newer RO technology over time.
4. Livpure — Best Fast-Growing Brand
★ Key Features
- Part of the SAR Group: Livpure was built by Rakesh Malhotra and Navneet Kapoor under SAR Group, which also owns battery and inverter brands like Livguard.
- 7-Stage Purification: Most Livpure RO models pass water through seven filtration stages, including copper infusion on select units.
- Handles High-TDS Water Well: Rated to treat input water with TDS levels up to 2000 PPM, which suits most Indian groundwater sources.
- Taste Enhancer Technology: A feature many competitors don’t emphasize, aimed at improving the actual taste of purified water, not just its safety.
- Strong E-Commerce Presence: One of the more visible water purifier brands on Amazon India, with frequent model updates.
✔ Pros
- Competitive pricing relative to feature set
- Good performance on high-TDS groundwater
- Compact designs suit smaller Indian kitchens
- Filter-change indicators built into most models
❌ Cons
- Installation and service experience has drawn mixed feedback from users
- Smaller offline service network than Eureka Forbes or KENT
Livpure — Best for Value-Focused Online Buyers
Livpure has grown quickly by focusing on compact design, taste-enhancing technology, and a strong online retail presence. It’s a solid pick if you’re comfortable buying and troubleshooting mostly online rather than relying on a dense offline service network.
5. Blue Star — Best Premium Design
★ Key Features
- 80+ Years as a Company: Blue Star was founded in 1943 by Mohan T Advani and built its name in air conditioning and commercial refrigeration long before entering water purifiers.
- Entered Water Purifiers in 2016: A newer category for Blue Star, launched with a stylish, differentiated range across four series — Stella, Prisma, Edge, and Majesto.
- Alkaline Antioxidant Cartridge: A distinctive feature that adjusts water pH, aimed at buyers specifically looking for alkaline drinking water.
- RO+UV+UF Combination: Standard multi-stage purification across most models, suited to a range of water conditions.
- Leverages an Existing Service Network: Benefits from Blue Star’s long-standing AC and appliance service infrastructure across India.
✔ Pros
- Distinctive, premium product design
- Backed by a well-established, financially stable parent company
- Alkaline antioxidant option not common across other brands
- Existing nationwide service infrastructure from Blue Star’s AC business
❌ Cons
- Newer to water purifiers than the other brands on this list
- Performance can drop in low water-pressure conditions
Blue Star — Best for Style-Conscious Buyers
Blue Star’s purifiers stand out on design first, backed by a parent company with a genuinely long track record in cooling and appliance service — even though water purifiers themselves are a relatively recent addition to its lineup. It’s a strong pick if aesthetics and brand stability matter as much as raw purification specs.
🛒 How to Choose the Right Water Purifier Brand
Know Your Water’s TDS Level
RO purifiers are built for high-TDS water (typically above 500 PPM), while UV or UF-only purifiers suit lower-TDS water with mainly microbial contamination. Buying an RO purifier for already-low-TDS water strips out minerals unnecessarily and wastes water in the process.
Electric vs. Non-Electric
Non-electric, gravity-based purifiers like Pureit’s Classic range work without power — useful in areas with frequent outages — but can’t remove dissolved salts the way RO systems can. Electric RO/UV purifiers cost more to run but handle a wider range of water conditions.
Service Network Availability
Filters, membranes, and UV bulbs all need periodic replacement. Brands like Eureka Forbes and KENT have the densest offline service networks in India, which matters more in smaller towns than in metro areas with easy access to online support.
Storage Capacity vs. Family Size
Match tank size to household size — smaller 5-7L tanks suit 2-4 person households, while larger 10L+ tanks or higher-throughput models make more sense for bigger families or homes with frequent guests.
Warranty & Filter Replacement Costs
The purifier’s upfront price is only part of the cost — factor in filter cartridge and RO membrane replacement costs over a few years, since these vary significantly between brands and can add up to more than the purifier itself.
Mineral Retention
Standard RO systems strip out beneficial minerals along with contaminants. If this matters to you, look for models with mineral cartridges or alkaline technology, like KENT’s Mineral RO or Blue Star’s alkaline antioxidant cartridge.

❓ Frequently Asked Questions
1. Is Pureit still owned by Hindustan Unilever (HUL)?
No. HUL sold its Pureit water purification business to global water-technology company A. O. Smith in a deal that closed in November 2024. Pureit products, service, and support are now managed by A. O. Smith India Water Products.
2. Do I need an RO purifier, or will UV/UF be enough?
It depends on your water’s TDS level. RO is necessary for high-TDS water (common with borewell or groundwater sources), while UV or UF alone is often sufficient for municipal water with lower TDS but potential microbial contamination. A water testing kit or local water report can confirm which you need.
3. Which brand has the best after-sales service in India?
Eureka Forbes and KENT generally have the widest offline service networks, which matters most in smaller towns and cities. Newer or more online-focused brands like Livpure may have thinner offline coverage in some regions.
4. Are non-electric water purifiers as effective as electric RO purifiers?
Non-electric, gravity-based purifiers (like Pureit Classic) are effective against microbial contamination but cannot remove dissolved salts or heavy metals the way RO systems can. They work best for lower-TDS water where the main concern is bacteria and viruses, not dissolved solids.
5. How much do filter and membrane replacements typically cost?
This varies by brand and model, but budget for filter cartridge and RO membrane replacement roughly once or twice a year, depending on usage and input water quality. Over a purifier’s lifetime, these costs can add up to more than the purifier’s original price, so it’s worth checking replacement costs before buying.
6. Does RO purification remove essential minerals from water?
Yes, standard RO systems remove most dissolved minerals along with contaminants. Many current models address this with dedicated mineral cartridges or alkaline technology that adds minerals back after purification — worth looking for if this is a priority for you.
💧 Final Thoughts on the Best Water Purifier Brands in India
All five brands here have genuine strengths, so the right pick comes down to what matters most to you. For the widest service network and broadest range of purifier types, Eureka Forbes is the safest all-round choice. If you want the most advanced purification technology available, KENT leads the pack. Budget-conscious buyers or anyone dealing with frequent power cuts should look at Pureit, now backed by A. O. Smith. Livpure is worth considering if you’re buying online and want a compact, taste-focused purifier at a competitive price. And if design and brand pedigree matter to you, Blue Star brings decades of appliance experience to a newer, stylish purifier lineup.
Whichever brand you choose, get your water’s TDS level checked first — it’s the single biggest factor in picking the right purification technology. And if you’re setting up your kitchen or utility area at the same time, it’s worth checking our guide to the best washing machine brands in India too.
