Related Buying Advice
For a standard bedroom up to 120 sq. ft, buy a 1 Ton Inverter AC. For 130–180 sq. ft, choose 1.5 Ton. If the room is on the top floor with direct roof sun or large west-facing windows, size up by 0.5 Ton. Look for an ISEER rating above 5.0 for maximum power savings.
Home AppliancesFor Indian winter pollution where AQI crosses 400+, insist on a True HEPA H13 filter with a Clean Air Delivery Rate (CADR) of at least 300 m³/hr for bedrooms and 450+ m³/hr for living rooms. Always calculate annual filter replacement cost (₹2,000–₹4,000) before choosing a brand.
Home AppliancesIf your input water TDS is below 250 ppm (municipal / Kaveri / Ganga / Yamuna river water), you DO NOT need an RO; a UV+UF purifier provides 100% sterile water with zero water wastage and zero mineral loss. If input water TDS exceeds 300–500 ppm (borewell or tanker water with heavy dissolved salts), an RO purifier with mineralizer is mandatory.
