Performance
The Cooler benefits from three speeds - low, medium and high (revolutionary, right?).
There is a fourth option whereby you can have the highest setting on permanently.
It also benefits from an adjustable vent so you can direct the airflow to your liking.
How Does It Work?
Well, I could be scientific here - but I never listened in physics so I won't.
Essentially, the Cooler System draws air from your room into the fan. That air is then pushed through the filter which is now soaked in cold water. The air is instantly chilled and then pushed into your room or personal space.
Filter?
Ok, so the filter has one primary function: to trap any unwanted bacteria or debris as it passes through.
This allows the air to retain moisture and avoid that dryness you'd normally encounter with conventional fans. Additionally, the air is recycled as it makes each pass through the filter.
The filter can be cleaned in the dishwasher, by hand and / or sanitised in the microwave. Cleaning should be undertaken weekly for optimum performance.
