Common Questions About Evaporative Coolers

What is an 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.

The best evaporative air cooler review

Dimplex DCEVP6 Portable Evaporative Cooler

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 comes 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.

If you’re looking for the best portable evaporative coolers, you’d be hard pushed to find something better than the Dimplex.

DeLonghi EV290 Evaporative Cooler

The Delonghi EV290 has a sleek and modern design so it won’t look like an eye sore, making it one of the best home evaporative coolers on the market. This cooler also comes with two ice blocks so the machine can run for longer.

The water tank is only 5.5 litres but thanks to the added ice blocks this model can run for up to 7.5 hours without needing to be refilled. There’s an impressive range of settings, including a 7.5 hour “countdown timer” so you know when to refill, and the Delonghi has a particularly quiet “sleep” setting compared to other coolers.

The Delonghi’s filter system also collects and sterilises dust particles in the air, making the surrounding air cleaner and fresher to breath.

Lennox 10 Litre Evaporative Cooler

This model made it into the top 10 portable evaporative coolers because of its low price. It’s a great option if you just want to cool one small room or outdoor seating area. It does need a good airflow though so needs to be near a window or door, if inside.

The Lennox has an impressive 10 litre capacity water tank meaning it doesn’t need refilling very often and, at only 6kg, it’s very easy to move around the house.

If you want a cheap, no fuss unit, this could be a good option for you. However, remember what I said about “getting what you pay for” and don’t expect miracles.

Pronti 3.5L Evaporative Cooler

The Pronti is a very small unit that would be great to have in an apartment as it’s light, at just 5 kg, and the stable castor wheels mean it can easily be pushed from one room to another.

It’s not suitable for big properties but has a very low power usage so would be perfect for someone wanting to cool a particular room without drastically increasing their power bill.

It has a small 3.5 litre tank but does come with two ice water bottles to extend the run time a little. This unit comes with a remote control and very basic buttons on the unit itself so it’s easy for anyone to choose one of the 3 speed settings.

It does exactly what an evaporative cooler should do with no bells and whistles. Simple!

PolyCool CV800 4in1

The Polycool CV800 is marketed as an industrial evaporative cooler perfect for warehouses and large workshops. However, there is no reason it can’t also be a great option for your home too! 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).

The CV800 has an impressive 60 litre water tank and only uses between 2 and 5 litres per hour dependant on the setting you use. So, you can potentially get 10 hours runtime before having to refill the tank!

Online reviewers consistently commend the quality and power you get for a relatively low price.

Devanti 8.5L Evaporative Cooler

The Devanti is another great budget evaporative cooler and comes in at under the $100 mark. It’s another, relatively, small unit but it would be suitable for an apartment or dorm room, as long as there is good airflow from an open window.

The 8.5 litre capacity tank is impressive for such a small machine and will give you around 7 hours run time. It also has a large range of settings including a timer, wind class, fan speed and automatic swing function.

The dust filter will also make sure your air is wonderfully clear and fresh feeling and the Devanti is a real contender for the best air cooler, Australia.

This personal evaporative cooler has some great little features. As with the previous product, it’s great to have around the bed area or work station to keep the air flowing and humidified but it also has a few extras that make it a little more usable.

This machine has a handy viewing window into the water tank so you can quickly check the water level. The helpful handle make it super easy to carry around with you from room to room. It also has 4 caster wheels so it can be pushed around the work bench or spun in a different direction easily.
