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.

Explore Home Deals ➜🎯 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:
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.
Frequently Asked Questions
Q1: Does the 2-year free service cover all filters?
Yes, the 2-year comprehensive warranty covers all consumable filters and the RO membrane, provided they are replaced as per the machine’s smart alert system.
Q2: What is the benefit of Alkaline water in this purifier?
It balances the pH level of water (making it pH 8-10), which helps neutralize body acidity, improves metabolism, and provides better hydration compared to regular RO water.
Q3: Can it handle very high TDS levels?
Yes, the Havells FAB Alkaline is designed to work efficiently with all water sources including Borewell, Tanker, and Municipal water with high TDS levels.
Q4: Is the storage tank detachable for cleaning?
The tank is integrated and covered to prevent contamination, but it features a zero-splash tap and is made of food-grade material for easy maintenance.
Q5: Is installation free for this model?
Yes, Havells typically provides free standard installation. You can book the service immediately after the product is delivered via their toll-free number.
💡 Hidden Hacks for Long-Term Performance
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.
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.
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
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.
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.
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.
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.
The Final Verdict
(Expert Performance Rating)
Should you buy it? Absolutely. If your priority is healthy, Alkaline drinking water and you want to avoid the headache of service costs for the first two years, the Havells FAB Alkaline is a winner. While the initial investment is slightly premium, the ₹10,000 savings on maintenance and the advanced 8-stage safety make it a top-tier choice for any modern Indian home.
