What is the 2-way airflow mode?
LG AeroTower was designed for the most discriminating user who wants options when it comes to airflow—dynamic mode and natural wind mode. Dynamic airflow with the Wide mode can cool a larger room quicly, setting wind strength to between stages 1 and 11. And Gentle breeze with the Natural wind mode automatically adjusts the wind strength, producing a pleasant wind similar to the nature's as if you are outside.
