The LG LS-K2430HL 23000 BTU Heating and Cooling Mini Split Unit. LG raises the standards of Mini Split units with high SEER of 10, Multi Power System Energy-saving twin compressors: one provides power at 60% capacity until the system reaches a desired temperature and the other takes over to provide sustained operation at 40% capacity. Chaos Swing - Computer controlled vanes create a more natural flow of air, reducing temperature stratification. Ultra-Quiet Streamlined Air Fan - Interior units have a cross-flow fan that operates at low speed but generates more air. Special fan housing creates smooth, quiet air flow and the unit's low-voltage DC motor operates with minimal noise. Jet Cool - Operates at high speed for up to 30 minutes to quickly cool a room down to 65?? F. Triple-filter air purifying system - An electrostatic filter removes dust, pollen and smoke; an anti-fungal filter prevents bacteria and mold from forming; and a deodorizing filter constantly freshens the air.
