Questions before you buy
Is aircon or an air cooler better for a bedroom?
Aircon is more appropriate when you need active temperature reduction and can vent the exhaust. An air cooler may suit someone who wants a localised breeze without installing a hose, provided added humidity is acceptable.
Can I use an air cooler instead of aircon?
You can use it as a different kind of comfort appliance, but it will not perform the same heat-removal job. Do not expect an evaporative model to hold a set temperature like an air conditioner.
Does aircon need a window open?
A portable air conditioner needs its hot exhaust directed outdoors, usually through a window kit. A split air-conditioning system uses an outdoor unit instead.
Does an air cooler use water?
An evaporative air cooler uses a water reservoir and cooling media. Air conditioners do not use a room-side water tank in the same way; check the specific product’s drainage instructions.
