Common Questions About Evaporative Coolers
What is a evaporative air cooler?
So, here’s the sciencey bit. I’ll try make it as easy to understand as possible!
The best evaporative air coolers all work in basically the same way. They use the surrounding heat energy in the air to turn water into vapour and distribute it back around. So, the heat is used up and cooler water vapour is produced.
A fan draws the hot, dry air into the unit and through damp pads which turns the liquid water, in those pads, into water vapour. Another fan then blows that water vapour back out into the surrounding area, thereby lowering the temperature of the room.
How well do evaporative coolers work?
Evaporative coolers can be one of the best room coolers in the right conditions. The drier the air in your house the more effective they will work and the more noticeable results will be.
As long as you learn how to use portable evaporative coolers properly they can be a viable alternative to air conditioners. Make sure to have them near a window or door left ajar so there is a steady air flow.
It’s true that air conditioners will probably deliver better cooling power in most cases. However, considering the huge difference in price, if you have the right climate evaporative coolers can be a very good alternative.
Do air coolers work in humid climates?
No, the air needs to be hot and dry for evaporative coolers to work. Even the best rated evaporative coolers can’t work if the air is already filled with water.
How much water does an evaporative cooler use?
Evaporative coolers, use water to cool the air and that has to come from somewhere. Portable coolers need to be refilled manually to keep the pads moist.
Make sure to keep this in mind when shopping for the best portable air cooler. Look for models with a large tank capacity so you won’t have to refill them as often.
How much water the cooler will use varies widely and will depend on the power of the machine as well as a number of other factors.
Other Things To Consider

The Dimplex is our pick for the best air cooler for homes. It’s well under a metre tall with a small footprint so it’s very unobtrusive in any room.
The 6 litre tank capacity and 1.2 litre per hour water usage means the tank only needs refilling every 5 hours, which is impressive for such a small size. If you’d rather not refill the tank so often, you can upgrade to the 20 litre version for an about an extra $100
It come with a ton of different settings, including 3 modes (natural, normal and sleep), 3 fan speeds and a timer function. The control panel is simple and easy to use but it also comes with a remote control.
The Dimplex weighs about 7kg and the castor wheels are sturdy and make moving the unit from room to room very easy. The louvres also have an auto swing function which a lot of portable coolers don’t seem to have.

Set it up in a room with good airflow and leave the doors open into the adjacent rooms to get some impressive results.
This is also a great option for cooling an outdoor entertaining or dining area. It’s heavier than the other suggestions so not as portable but still has sturdy, lockable castor wheels and it’s possible to push the unit around (although this could be hard on carpet).
