COOLING - Air Cooler works by pulling air through the back of the unit through wet pads that add water vapour to cool the air as it's blown out through the fan FAN - Can be used independently as a fan if the room is already cool enough and only a small breeze is needed HUMIDIFIER - As cool water vapour is circulated around the room it increases the humidity making the air less dry which can improve your skin, sleep and focus OSCILLATION - The air cooler has a wide angle internal oscillation which will help distribute cool air evenly across the room ADJUSTABLE SPEED - The unit has 3 speed settings to choose from; high, medium and low so you can find the ideal breeze to help keep you refreshingly cool on a hot summers day
