Active Specifications, Features & Compatibility Guide
The Active is a Havells UV-based water sterilization system designed for Indian households where municipal supply water has low TDS but carries microbiological contamination risk from bacteria and viruses.
Quick Answer
Opt for the Havells Active UV Sterilizer if your Indian home needs reliable protection against waterborne pathogens in low TDS municipal supply. This system delivers 4-stage purification specifically targeting bacteria and viruses, a critical feature often overlooked. Its BEE-rated efficiency also ensures lower long-term operational costs, making it a robust, economical choice for residential health and safety.
The Active UV Sterilizer is an excellent investment for Indian households seeking a high-efficiency, BEE-compliant solution for microbial contamination in municipal water. Choose this unit for dependable health protection and reduced running costs, but reconsider if your priority is minimal initial expenditure or your usage demands exceed typical residential capacity.

- •Environments incompatible with uv water sterilizers physical and thermal dissipation specs.
Product Overview
The Active is a Havells UV-based water sterilization system designed for Indian households where municipal supply water has low TDS but carries microbiological contamination risk from bacteria and viruses. The 4 Stages-stage purification system using [object Object],[object Object] technology removes both physical impurities and biological pathogens in a sequential process before delivering safe drinking water. The 11 WW UV lamp delivers germicidal UV-C radiation at the wavelength required to neutralize 99.99% of bacteria, viruses, and cysts — without adding chemicals or altering the mineral content of the water. At Up to 60 L/hr litres per minute flow rate, the Active provides purified water quickly enough to serve the daily drinking and cooking needs of a typical Indian family of four without inconvenient waiting. A filter change indicator alerts users when purification media needs replacement, ensuring purification performance never degrades without warning. The UV lamp indicator confirms the germicidal lamp is functioning correctly — if the lamp fails, the indicator warns users immediately to prevent consumption of potentially unsafe water. Havells provides a 1 Year product warranty.

Engineering Analysis
UV water sterilization operates on the principle of photolytic disruption of microbial DNA. As water flows past the 11 WW UV-C lamp, microorganisms absorb UV radiation at 254nm wavelength. This breaks the molecular bonds in their DNA, preventing replication and rendering pathogens unable to cause infection. Unlike chlorine disinfection, UV leaves no residual chemical taste and does not produce harmful disinfection byproducts (DBPs) like trihalomethanes. The multi-stage filtration preceding UV treatment is engineered to reduce turbidity (suspended particles) before water reaches the UV chamber. This is critical because high turbidity can shield microorganisms from UV exposure — a phenomenon called "shadowing." Pre-filters remove sediment, rust, and colloidal particles to ensure the UV dose is applied effectively to the entire water stream. UV lamp intensity degrades over time even before complete failure — typically losing 20-30% output over the lamp's rated lifespan. The UV intensity indicator in the Active monitors actual lamp output rather than just detecting complete lamp failure, alerting users when output drops below the threshold required for reliable germicidal performance.
