Havells FAB Alkaline: In-Depth Review

💧

Premium Water Quality & Taste

The core strength of the Havells FAB Alkaline is its ability to deliver naturally sweet and refreshing water. While standard RO systems often make water taste “flat” or slightly acidic, this model uses advanced Alkaline technology to maintain a pH level between 8 and 10. This not only improves the taste but also helps in balancing body acidity and boosting metabolism.

🛡️

8-Stage Advanced Purification

Havells ensures 100% safety by using a powerful 8-stage process. It combines RO and UV filtration to eliminate 99.9% of harmful bacteria and viruses. A standout feature is the Mineralz Guard, which retains essential natural minerals like Calcium and Magnesium that are often lost in ordinary RO purifiers. The Bio-Magnetic Revitalizer further enhances the water quality for better hydration.

📱

Intuitive Smart Alerts

The Smart LED indicators on the front panel take the guesswork out of maintenance. The system features a Self-Diagnosis tool that constantly monitors the machine’s health. You get specific alerts for Filter Life and UV Failure, ensuring that you never accidentally drink impure water.

💰

Industry-Leading 2-Year Free Service

This is the ultimate “X-factor.” Havells offers 2 years of comprehensive free service, covering all filter replacements and labor. In an industry where annual maintenance (AMC) costs can range from ₹4,000 to ₹5,000, this feature saves you approximately ₹10,000 over the first two years, making it a highly cost-effective premium choice.

🏠 Real-World Usage & Experience

🔹 Daily Performance

In a typical household setup, the Havells FAB Alkaline performs silently. The 7-liter tank fills up surprisingly fast, thanks to its high-flow RO membrane. Whether it’s for cooking or drinking, the water flow from the tap is consistent and steady.

🔹 Handling Different Water Sources

During our testing across various water sources (Borewell & Tanker water), the purifier efficiently brought down high TDS levels to a drinkable range (below 100) without making the water taste “metallic” or “bitter.” The Alkaline filter ensures the water stays light and easy on the stomach.

🔹 Maintenance Convenience

The most practical benefit in real-world usage is the Smart Alert system. You don’t need to mark your calendar for service; the machine tells you exactly when it’s time. Plus, the 2-year free service means you won’t be reaching for your wallet every time a technician visits for a filter check.

Easy to Clean: The smooth exterior finish only requires a simple wipe with a damp cloth to keep it looking brand new.
Space Saving: Its compact wall-mount design ensures it doesn’t clutter your kitchen counter, even in smaller apartments.

🎯 Who Should Buy the Havells FAB Alkaline?

This water purifier isn’t for everyone. It is specifically designed for a certain group of users who value health and long-term peace of mind. You should consider this if:

📍 High TDS Areas If your home gets Borewell or Tanker water with high salt content (TDS), this RO system is a must-have.
🥗 Health Conscious Families If you want the benefits of Alkaline water (pH 8+) for better digestion and immunity.
💰 Budget Planners If you want to avoid paying ₹4,000–₹5,000 every year for service, the 2-year free service makes this a smart choice.
🏢 Apartment Dwellers Perfect for modular kitchens where space is limited but style and performance are essential.

Note: If your input water already has very low TDS (below 200) and you are on a very tight initial budget, a simple UV purifier might be enough for you.

Pro Tip

💡 Hidden Hacks for Long-Term Performance

🚀 The Pre-Filter Hack:

Even though Havells gives 2 years of free service, always use a high-quality External Pre-Filter (Sediment Filter). This costs just ₹300-₹500 but it prevents heavy mud and sand from entering your main machine, making your expensive RO membrane last much longer than 2 years.

⚡ Smart Power Usage:

During rainy seasons or heavy voltage fluctuations, use a small Voltage Stabilizer. The smart sensors and LED display in the FAB Alkaline model are sensitive; protecting them will prevent “Ghost Alerts” or sensor failures.

💧 The First-Fill Rule:

After installation, discard the first two full tanks of water completely. This helps to flush out any loose carbon dust and fully activates the Alkaline filter and Copper revitalizer for the best taste.

⚠️ Important Points to Consider Before Buying

01
Inlet Water Pressure:

Like most RO systems, this model requires a specific inlet pressure. If you live on the top floor of an apartment with low water pressure, you might need to install an additional booster pump.

02
Service Availability:

While Havells offers 2 years of free service, always verify if there is a Havells authorized service center in your specific pin code to ensure quick response times.

03
Power Dependency:

The smart alerts and purification process require a continuous power supply. If your area has frequent long power cuts, ensure you have a backup power source to keep the tank full.

04
Reject Water Management:

Being an RO system, it will reject some water during the process. We recommend placing a small tank or bucket near the outlet to reuse this water for mopping floors or watering plants.
