The HD Filter with Anti Virus Protection provides a robust filtration system that effectively captures dust, allergens, and harmful particles, including viruses. Why this matters: This ensures significantly cleaner and healthier indoor air quality for your family, a vital consideration in today’s environment.
Gold Fin+ Condenser: Enhanced Durability
The outdoor unit features Gold Fin+, a special anti-corrosion coating on its condenser coils. Benefits: This coating provides robust protection against rust, corrosion, and environmental damage from humidity, salt, and pollutants prevalent in diverse Indian climates. This significantly enhances the AC’s durability and extends its lifespan, ensuring reliable performance for years to come.
Stabilizer Free Operation (187V ~ 276V): Convenience and Protection
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 in India, safeguarding your appliance.
Auto Cleaning & Heat Exchanger Cleaning: Simplified Maintenance
The Auto Cleaning feature is crucial for hygiene, preventing the build-up of bacteria and mold by automatically drying the heat exchanger after cooling cycles. This, combined with explicit Heat Exchanger Cleaning capabilities, ensures healthier air and maintains unit efficiency and longevity.
Low Noise Operation (30 dB IDU): Peaceful Environment
The indoor unit operates quietly, with a low noise level of 30 dB (on low fan speed). This ensures a peaceful and undisturbed environment for sleep, work, or relaxation.

- Made in India: Manufactured in Noida, India, supporting local production and potentially faster serviceability.
Cons:
- Cooling Only (C/O): This model does not offer heating functionality, making it less versatile for regions experiencing cold winters.
- Remote Controller Type: Listed as “Basic,” suggesting it might lack advanced display features, backlit buttons, or specific quick-access modes compared to more premium smart remotes.
- ODU Noise (Estimated 53 dB): While the indoor unit is quiet, the outdoor unit noise is typical for LG at around 53 dB. This might be a factor for sensitive users if the outdoor unit is placed very close to living spaces or bedrooms.
- Limited Vertical Airflow Control: The description mentions 4-Way Swing (Up-Down) but doesn’t explicitly state Left-Right swing. If it only has vertical swing, uniform cooling in wider rooms might be slightly less efficient.
- No Explicit Mention of 100% Copper: While Gold Fin+ implies good coil material and durability, it doesn’t explicitly state “100% Copper” for the internal piping, which some consumers prefer to see as a distinct feature.
