Key Features
Plasmaster™ Ionizer+ Active Purification
Generates over 8 million plasma ions that disperse throughout the room. These ions attach to bacteria, allergens, and odors, inactivating up to 99.9% of microscopic contaminants for a healthier indoor atmosphere.
DUAL Inverter Compressor Efficiency
LG’s dual-rotary compressor adjusts motor speeds continuously rather than cycling on and off. This design maintains steady room temperatures, reduces mechanical vibration, and cuts electrical running costs.
AI Air Smart Climate Management
The integrated AI system evaluates temperature trends and user settings set in the LG ThinQ® app. It automatically adjusts louver angles and fan speeds to maintain even room comfort without direct drafts.
LG ThinQ® Mobile Control
Factory-embedded Wi-Fi enables remote access via the LG ThinQ® app. Users can pre-cool rooms, track electricity usage, set weekly timers, and link to Google Assistant or Amazon Alexa voice devices.
Auto Clean+ & Freeze Cleaning Sanitation
Keeps internal components free from mold and odor accumulation by automatically drying the heat exchanger after use. Freeze Cleaning freezes moisture on the coil to wash away trapped dust particles during defrosting.
Gold Fin™ Anti-Corrosion Protection
The outdoor condenser coil features LG’s specialized Gold Fin™ coating. This anti-corrosion surface layer shields heat exchanger fins against salt air, rain, and environmental pollutants for longer outdoor life.
Ideal Applications
- Master Bedrooms & Suites: Plasmaster™ Ionizer+ and Soft Air indirect airflow create ideal sleeping environments.
- Medium Living Rooms & Apartments: 3.5 kW capacity conditions 20–30 m² open areas efficiently.
- Asthma & Allergy Sufferers: Active plasma ion generation neutralizes pollen and airborne micro-particles.
- Coastal Homes: Gold Fin™ outdoor coating resists corrosion caused by salty ocean air.
