8 Best Evaporative Coolers of 2018

If you live in a hot and dry area, you just know that having cool air is the best feeling ever. Having an evaporative air cooler in your home is everything. It is as if you have been wandering the desert for years and finally, you see an oasis to have a drink and cool yourself.

Evaporative coolers evaporate the water and turn it into a cool mist. The cooling pad absorbs the hot air so that only cold air is released into the room. If an air conditioner is too expensive for you, an evaporative cooler is a good alternative.

Factors to Consider When Choosing the Best Evaporative Cooler

The Climate of Where You Live

Evaporative coolers work best in places where there is a hot and dry climate. The coolers draw the warm air in and cooled through a moisture pad and then releases it. It is only ideal for cooling air but not lowering the overall temperature of your home.

Do your research first and find out the level of humidity in your area. Some units work best for different levels of humidity.


Consider the living space in your homes. Do you have enough space for a bigger size of an evaporative cooler or do you have room for just a smaller one? Do you also plan to move it from room to room whenever you need to?

Some can cool air for a bigger area of the room while some can only spot cool. If you live alone, spot cooling would be enough. For transport, some units have casters that make it easy enough to be pushed to a different location.

Evaporative Cooler or Air-Conditioner

Both of these have ups and downs. If your main goal is to lower the room temperature significantly, an air conditioner would be best. However, if you just want a bit of cooler and fresh air, an evaporative cooler is a good option.

Compared to an AC, evaporative coolers consume less energy so it will not drastically increase your monthly bills. It is also more environmentally friendly because they have a natural process of cooling the air.

Ease of Use

If you are not the handy kind of person, an evaporative cooler that is ready out-of-the-box should be the option for you. Still, make sure to read the manual first to learn how to learn the ropes like how to put the water or ice cubes.

Remember that regular cleaning is also required to make it worth the purchase. Proper maintenance and cleaning will make it last longer.

If you really just want an evaporative cooler and the money does not matter, you might as well go with the Rabbit Air BioGS 2.0. It is very efficient and has received awards to prove its quality. The levels it takes to purify and deodorize the air is impressive.
