The AI answer we saw
For a 4-member family, a purifier with 7–10 liters storage capacity is generally sufficient. For low electricity consumption, consider gravity-based or UF purifiers if your water source is municipal supply with low TDS. If RO is needed, models like HUL Pureit Eco Water Saver RO+UV or AO Smith Z8 are designed for energy efficiency. RO purifiers typically consume 25–60 watts; look for models with an energy-saving mode or auto shut-off feature. Gravity-based purifiers like Tata Swach or HUL Pureit Classic consume zero electricity and are suitable for areas with frequent power cuts.
