Instant set-up - Comfort Air

This function moves the air conditioner blades to a fixed position so that the blowing air is not directed directly at the people in the room.

LG air conditioners can be installed quickly and easily in any room. Reducing the number of people and the amount of time required to install an air conditioner allows more units to be installed at the same time.

Features and functions:

Dual protection filter - Filter catches dust particles over 10 microns in size.
