The evaporative air cooler or swamp cooler is an ingenious way of cooling your room by using the natural powers of evaporation.
Essentially, the evaporative air cooler contains a water tub inside with a fan blowing over the water.
This water evaporates and exits the evaporative air cooler which then replaces the hot and dry air in your room with cool and moist air.

Evaporative Air Cooler vs. Air Conditioner
Photo: DeLonghi
There are several key differences between the evaporative air cooler and the regular air conditioner. Here are a few of the most common differences:
1. Operation Costs
Since the evaporative air cooler is simply a big fan that blows over a tray of water, it consumes less power when compared to the air conditioner which has more complex functionality.
At the end of the day, you will pay significantly less for operating the evaporative air cooler than the air conditioner.
2. Operation Mode
With the regular air conditioner, you have to close all doors and windows for the power saving mode to kick in.
If you do not close your doors and windows, the air conditioner will consume an extremely high amount of electricity trying to cool the entire room.
This is not a problem with the evaporative air cooler because regardless of whether your door or window is open, the power consumption remains the same.
3. Moisture Level
The big problem with air conditioners is that they remove moisture from the air.
This dry air is not very healthy and can cause a wide range of health issues ranging from asthma, allergies, dry eyes, dry skin, etc.
On the other hand, the evaporative air cooler adds moisture to the air so that it makes it cooler. The cool air is a more natural air to the body which will be more comfortable.
4. Environment-friendly
The air conditioner emits a high level of CO2 which proves to be dangerous to the environment over the long term.
Indeed, a high level of CO2 in the atmosphere contributes to the warming up of the planet.
Additionally, the air conditioner is an electric device that produces a fair amount of noise when it is operational.
Therefore, if you have your air conditioner switched on at night, then you will definitely hear it whenever it starts working.
With the evaporative air cooler, you do not have any of those problems.
It either does not emit any CO2 or a very small amount of it, and it is silent in operation.
5. Portability
The biggest advantage of the evaporative air cooler is portability. Indeed, since most evaporative air coolers are quite lightweight, they can easily be carried around in the house.
Additionally, many of those coolers have rollers at the bottom so that you can drag them easily.
How to Buy the Best Evaporative Air Cooler
Photo: Luma Comfort
One of the most important aspects to consider when trying to find a top-rated evaporative air cooler for the money is the climate.
Indeed, your choice will depend on the weather or environment where you will be using the evaporative air cooler.
This is because this device is more useful in hot and dry environments than cold and moist ones.
If you live in a hot climate, like a desert, then the evaporative air cooler will be the most effective.
It will be able to add a higher concentration of water vapor in the air, making it cooler.
1. Air Flow
The airflow is measured in CFM and is basically how much moisture the evaporative air cooler can add to the air in a given period of time.
For most people, and evaporative air cooler that can output at least 300 CFM is more than enough.
However, if you have a big room. Or you need your evaporative air cooler to cool the air as fast as possible; then it is always best to go with a model with a high CFM value.
Knowing the exact CFM value for your cooler is quite easy.
All you have to do is know the square feet area you need to cool. Then multiply it with the height of the room ceiling and divide this number by 2.
As an example, if you need to cool an area of 500 square feet and the room has a ceiling height of 8 feet, you will need a 2,000 CFM evaporative air cooler. (500 x 8 /2 = 2,000 CFM)
Keep in mind that an evaporative air cooler with a higher CFM will also generally output more noise.
So, if noise levels are important to you, it is best to go with a lower CFM air cooler.
2. Maintenance
Since the evaporative air cooler comprises a fan and a series of filters, it will attract dust.
Therefore, regular maintenance is necessary for both the proper functioning of the evaporative air cooler as well as for your health.
If you use your evaporative air cooler daily, then we recommend that you perform maintenance every 2 weeks.
You can use lukewarm water and a mild detergent to clean the fans as well as the filters of your evaporative air cooler.
In addition, sometimes you may need to store your evaporative air cooler for an extended period of time. This usually happens when the season changes and you have no need for it.
To do so, you need to protect the evaporative air cooler by disconnecting it with any water line as well as unplugging it from the power supply.
3. Portability
One of the biggest advantages of the evaporative air cooler remains its portability. Indeed, it is usually a relatively lightweight device when compared to other types of careers that can easily be carried around.
But keep in mind that some of the best portable swamp coolers are not necessarily the lightest in terms of weight, but they still remain quite easy to carry around.
This is because they have bottom rollers, so you can easily drag them around in the room.
4. Energy Saving
Most people prefer the evaporative air cooler because it is an energy efficient device when compared to other cooling devices like the air conditioner.
There are no complex or power-hungry parts in the evaporative air cooler. This means that it will not add up too much in your electricity bill.
In fact, most reputable evaporative air cooler manufacturers will actually tell you how much energy in watts or amperage their coolers consume. They rarely go over 250 W.
Additionally, they will also tell you the humidity level you need to use for maximum efficiency.
Most of the time, this value is usually at 60 percent humidity level or less.
Conclusion
The evaporative air cooler is an absolute must-have if you live in a dry area. It will cool the air inside your room and make it significantly more pleasant.
By reading our evaporative air cooler review above, we can also see that they are also more affordable than traditional coolers like the air conditioner. Which is both more expensive and consumes more power.
