Atomberg Water Purifier Review | Intellon 2025

After daily use for over a month, the feature that impressed me most is the ability to adjust the output TDS range to match borewell, Tanker, or municipal water. You don’t need a separate TDS meter, you don’t have to guess when RO is necessary, and you’re never locked into a corporate AMC plan.

Design and Build

At first glance, Atomberg Intellon looks compact and clean, nothing flashy, yet not overly flat or plasticky like many unbranded RO models either. Its minimalist body houses an ABS Food Grade Plastic water storage tank, not stainless steel, which would’ve been more durable at this price point. That said, the food-grade tank is similar in quality to what’s used in premium models from other brands like Pureit or Urban Company.

The front panel display isn’t a touchscreen or rotary dial, it’s a crisp digital readout that shows essential info like TDS levels, error codes, and tank full indicators. Below that, you’ll find a water dispensing area that unfortunately lacks support tray. This means you need to hold the bottle or glass by hand during filling, which isn’t ideal when compared to the Urban Company Native M2 that includes a tray.

Connectivity is through Wi-Fi, but do note: the purifier doesn’t automatically detect your 2.4GHz network. You’ll need to manually select it during setup. Once connected, the app offers real-time updates on input/output TDS, filter life, tank status, and error codes, removing the guesswork from everyday usage.

Performance and Filtration Modes

The heart of this machine lies in its customizable purification logic. There are four main modes:

1. Adaptive Flow Mode

Ideal for low to moderately hard water (TDS < 250 ppm). It uses the inbuilt industry-grade TDS sensor to assess incoming water. If the TDS is below 250 ppm, the system skips RO purification and switches to other filters (like UV, UF, carbon), saving RO membrane life and reducing water wastage. However, avoid this mode if your water is chemically contaminated — even if TDS is low.

In fluoride-affected or industrial zones in States like Rajasthan, Gujarat, Karnataka, Andhra Pradesh, Telanga, West Bengal — it’s better to avoid Adaptive Flow Mode altogether (Minstry of Jal Shakti, NHM )

2. RO + UV Mode

This mode activates the full filtration stack. Use it when TDS is above 300 or 400ppm or when you suspect contaminants like fluoride, arsenic, or lead – even if TDS is below 250. It’s the safest option in areas where groundwater quality is unpredictable.

3. Taste Tune Mode

A unique offering that lets you choose the TDS range of the output water—for example:

• 50–100 ppm
• 75–125 ppm
• 100–150 ppm

You can’t lock a fixed number like “105 ppm” because both input and output TDS fluctuate slightly due to seasonal and supply variations. But this level of control is still rare in this price range. Taste Tune ensures the water tastes similar to Bisleri, mildly mineralized and balanced. Minerals like calcium, magnesium, and sodium are added during the final stage.

4. Vacation Mode

If you’re going out of town, this mode performs auto-flush every 48 hours, keeping the internal filters fresh and preventing bacterial buildup. It’s a small and thoughtful feature that most models ignore.

Water Wastage and Efficiency

No RO purifier is truly “zero waste,” and Atomberg Intellon is no exception. It discards about 1 litre for every 1 litre of purified water, which is standard in RO-based systems. However, by enabling Adaptive Flow Mode, the system intelligently avoids RO usage when it isn’t necessary — reducing both water wastage and wear on the RO membrane.

This selective activation means that in homes using low TDS water, like most municipal supply lines or treated tankers — you can avoid running RO cycles unnecessarily. But again, Adaptive Flow Mode should not be used if you’re in a fluoride-heavy zone or near chemical industries, even if your TDS is technically “low.”

The auto-flushing feature also plays a role in efficiency. It keeps the filters clean between uses, especially after long gaps, which indirectly extends filter life and maintains flow rates.

Maintenance and Service Costs

Where Atomberg really breaks away from traditional purifier brands is in honest pricing and lack of AMC lock-ins. For the first two years, all servicing including filter replacement is covered under warranty.

After the two-year mark, here’s what replacement filters cost individually:

• Pre-filter: ₹200 (often supplied free)
• Sediment filter: ₹430
• Pre-carbon filter: ₹490
• Membrane protector: ₹250
• RO membrane: ₹1,100
• Alkaliser/Mineral cartridge: ₹490

That adds up to ₹2,960 for a full overhaul. Even if a service fee (₹300–₹400 approx) is added, it’s still much lower than branded AMC plans.

By contrast, Urban Company charges ₹4,500 for two years (post-warranty), which includes parts and service. While that offers predictability, Atomberg gives you freedom —you only pay when a part truly needs replacing. And the app even notifies you in advance when a component is nearing its end of life.

Booking service is done directly via the app. Installation was completed the day after delivery in our case, and service was handled by Atomberg’s own technician and is not outsourced to third parties. Their model is similar to their fan business — city-based dealership networks rather than scattered vendors.

Atomberg Intellon vs Urban Company Native M1/M2

Let’s look at how the Atomberg Intellon stacks up against its closest rivals.

While UC Native M2 offers a slight convenience edge with its bottle tray and tray-press design, it cannot dispense water if there is no active power supply even when the tank is full.

Atomberg wins in customization, clarity of data, and app integration. For anyone moving between homes or dealing with mixed water sources, Intellon offers more flexibility.

Water Taste and Mineral Output

Taste is subjective, but Atomberg Intellon gets it right. The water tastes clean, slightly sweet, and very similar to packaged options like Bisleri. This is mainly due to the alkaliser/mineral cartridge, which reintroduces essential minerals like calcium, magnesium, and sodium into the water after RO purification.

The Taste Tune Mode lets you choose a TDS output range – either 50–100, 75–125, or 100–150 ppm. While you can’t set an exact number (because output depends on input quality and tank fill cycles), the purifier consistently delivers within your selected range. The sweet spot in our tests was the 75–125 ppm setting. It balances taste and mineral content while keeping RO wear under control.

Do note: copper is not added, unlike in some Livpure or Aquaguard models but the basics are well covered. For most users, the taste will feel very natural and not overly flat like generic unbranded RO systems.

Pros and Cons

What We Liked

• Smart Mode Selection: Automatically avoids RO where not needed, saving water and filter life.
• TDS Customization: Taste Tune gives real control over output.
• No AMC Trap: You’re not forced into annual plans.
• Transparent App: Filter health, TDS, error codes, all visible in one place.
• Wide Water Compatibility: Works with borewell, Manjeera, tanker, and municipal water.
• Service Network: Fast installation, dealer-based support (not third-party aggregators).
• Vacation Mode: Auto-cleaning every 48 hours keeps filters fresh even when you’re away.

What Could Be Better

• No Stainless Steel Tank: Uses food-grade ABS plastic. Safe, but at this price, steel would add long-term confidence.
• No Bottle Tray: Unlike UC Native Models, you’ll have to hold bottles by hand.

Important: If your water pressure is below 10 PSI, you will need to install a pressure booster for the Atomberg Intellon water purifier. Currently, Atomberg is offering the pressure booster free of cost.

Final Verdict

At ₹16,999–₹17,999 on Amazon , it’s not the cheapest, but you’re buying control, flexibility, and transparency. And for many households, especially renters or those with changing water conditions, that’s exactly what a modern water purifier should offer.
