Superior Air Hygiene & Robust Durability: Health and Longevity
Beyond cooling, the LG US-Q19JWZE prioritizes the air quality you breathe and the longevity of your investment.
HimClean Technology: Self-Cleaning for Healthier Air
This advanced self-cleaning feature automatically dries the heat exchanger inside the indoor unit after cooling cycles. This crucial process actively prevents the formation of mold, bacteria, and unpleasant odors, ensuring the air circulated is consistently cleaner and healthier. It also simplifies maintenance and promotes a hygienic environment. The inclusion of an Air Purifying Display provides visual confirmation of the air quality status.
4-Way Swing (Up-Down/Left-Right): Uniform Cooling
This vital feature ensures even and consistent air distribution throughout the entire room. By oscillating air both horizontally and vertically, it effectively eliminates hot spots and provides uniform cooling comfort, ensuring every part of your medium-sized room receives adequate airflow.
Cools Even at High Ambient Temperatures
While not explicitly stating a specific temperature (like 52°C), as a premium 2025 LG 5-star model with a Dual Inverter Compressor, this AC is engineered to deliver powerful and effective cooling performance even in the extreme high ambient temperatures commonly experienced during Indian summers.
Stabilizer Free Operation (187V ~ 276V): Protection and Convenience
Designed to operate reliably within a wide voltage fluctuation range, this AC offers Stabilizer Free Operation. This eliminates the need for an external voltage stabilizer, providing immense convenience and robust protection against common power surges and voltage drops prevalent in India.
Dehumidification
This essential feature effectively removes excess moisture from the air, enhancing comfort during humid conditions, particularly beneficial during the sticky Indian monsoon season, and helping prevent dampness and mildew growth.
Low Noise Operation (35 dB on low fan speed): Peaceful Environment
The indoor unit operates quietly, with a minimum noise level of just 35 dB on low fan speed. This ensures a peaceful and undisturbed environment for rest, work, or leisure.
