Evaporative air coolers are great for people who live in dry regions and need to keep cool. While most air conditioners work by removing water from the air, evaporative air coolers use water and evaporative action to cool the air. Since they don’t require compressors or Freon to work, they’re also an environmentally-friendly solution for a lot of people. That’s why we’ve taken the time to review some of the best evaporative air coolers so all of our readers can find one that matches their needs. Below are three models that we think will help our readers achieve the cooling that they desire.
Quick Summary of Best Evaporative Air Coolers
Editor’s Choice: Hessaire MC18M Portable Evaporative Cooler
Now that we’ve gone ahead and deemed this model the best evaporative air cooler currently available, at least by our standards, give us a moment to explain to you why we like this product. This product is not only portable and capable of cooling a large area, which we’ve already covered, but it’s also got some other features that we liked. For example, unlike some of the larger evaporative coolers, this one is extremely simple to fill and to keep filled.
With this model, the consumer doesn’t have to worry about spilling water all over the place when they fill it. And if the consumer wants to go with its continuous fill option by hooking it up to a water hose. It even comes with a brass float adaptor and float valve for this very person.
Another thing that we liked about this model was that it had four heavy-duty wheel casters that allowed it to be moved from one room to another. And we think that is the real strength of this model. It provides cooling where you need it because it can be moved from one area to another. And that’s why it’s at the very top of our evaporative air cooler list.
- It can cover up to 500 square feet.
- It has a good amount of airflow.
- It’s easy to move from one room to the next.

One of the things that it has going for it is that it can provide up to 194 cubic feet per minute of cooling, which is a nice amount of airflow for any cooler. Another thing that we liked about this cooler is that it’s extremely efficient and uses less energy than many other coolers. In fact, it only uses 50-watts of power—which is a minuscule amount when compared to some of the larger coolers that are being sold nowadays. We also liked the fact that since it was a little less than waist high and had vertical oscillation, it does distribute air nicely in a room.
Of course, those aren’t the only reasons why we enjoyed this air cooler. It also has a number of other features. It has 3 different fan speeds, a washable dust filter, and it has an alarm that alerts the user when the water levels have fallen too low. And it also comes with a remote control that allows the unit to be operated from across the room. But the best feature of all has to be that it doesn’t spit out water as some other air coolers do. That alone makes this product worth considering. So the consumer shouldn’t be quick to dismiss this cooler just because it’s a portable one. It’s still one that can provide a lot of people with a lot of uses. Sure, for bigger areas it doesn’t work as well, but for use as a personal air cooler, it works just fine.
- This is a portable evaporative air cooler.
- This can provide
- Only good for small areas.

Another thing that impressed us about this air cooler is that it has a 3-in-1 design that allows it to be used as an evaporative air cooler, as a fan, and of course, as a humidifier. It also has three different fan settings (low, medium, and high), that allow the consumer to set it according to their needs or the design of their room. We also appreciated the fact that this unit could be operated via remote control and had a 12-hour timer that automatically turned it off after 12-hours of use. That makes it a lot easier for the consumer to operate.
This product is 36-inches high and comes with four ice crystal boxes and instructions on how to operate the system. Each unit has two drains that make emptying excess water a breeze, a large air outlet that provides a wide cross-section of air, and wheels that make the unit easy to move from one area to the next area. All things considered, this is a decent air cooler, it’s just not the best one that we’ve ever reviewed. It is worth considering, however, and we’re sure it will work well for some people in some circumstances.
- It has three different fan speeds.
- It has a 7-gallon water tank.
- It’s equipped with dual drain ports.
- Doesn’t cool as well as other evaporative coolers.
A Guide To Evaporative Air Coolers
As we’ve seen with the above reviews, evaporative air coolers come in an assortment of different varieties and with different features. That’s why it’s important for the consumer to do their homework and make sure they absolutely purchase the best evaporative air cooler for your needs. With that as our absolute goal, let’s head on to some bullet points that all of our readers can use to make sure that they end up purchasing the best air cooler for their circumstances and needs.
Choose An Air Cooler Type
The first thing that the consumer should decide on before they purchase a new evaporative air cooler is what type they need. These coolers come in one of three different types and each of these types addresses a specific need. These three types are Portable, Residential, and Commercial. Let’s examine each one of them and see what they’re designed to do.
Portable Air Coolers
When it comes to swamp coolers, portable ones are pretty nice, especially if the consumer is just trying to provide themselves with cool air and aren’t trying to move air through a large room. Most of these types of coolers can handle spaces around 100-150 square feet, but there are some models that can provide cool air to larger spaces. The biggest positive of these coolers is that they’re easy to move from one space to another as needed, so the consumer can take the air with them.
Residential Air Coolers
These units are a little bigger than portable models, but they’re still small. They’re designed to provide spot-cooling, although there are some models that can cool a room over 500 square feet in size. We would consider these coolers halfway between portable air coolers and commercial air coolers.
Commercial Swamp Coolers
These evaporative air coolers are larger than either portable or residential models. That allows them to cool larger spaces but it also means that they’re all a lot more expensive than any of these other units. Their capacity for handling large areas makes them likely to be used for factories, warehouses, or aircraft hangars.
Choosing A Swamp Cooler Size
Evaporative air coolers also come in a variety of different sizes and are rated according to their CFM. CFM stands for cubic feet per minute and tells the consumer how much air these things push out at one time. The consumer should always make sure that they buy the right CFM cooler for the size of their room. So, start with the size of the space being serviced and then choose a cooler based on that space size.
For example, let’s say that you have a 550 square-foot room with 8-foot ceilings. First, you’re going to have to figure out the square feet of your room by multiplying the square footage of the room by the height of the ceiling. This gives you 4,400 (550×8).
Now, take that number and multiply it by 30. This will give you the air exchanges per hour. So, 4,400×30 gives you 132,00 air exchanges per hour. Now, divide that number by 60 to come up with the CFM. 132,000 divided by 60 equals 2,200 CFM. That’s the cubic feet per minute that your air cooler needs to have.
Adjust CFM For Unusual Or Nonstandard Circumstances
The above calculation for figuring out what CFM evaporative air cooler you need works when the consumer is figuring out the CFM for a standard room with an 8-foot ceiling. However, if the room isn’t standard, then the consumer might need to adjust the final figure so it’s more accurate. For example, if the ceilings are higher than 8-feet, there are more than 2-people that are going to use the space at one time, or the room has a lot of appliances that generate heat, then the consumer is going to want to adjust the final number upwards by 20%. For instance, the above example of our 4,400 square feet room will have to have its, 2,200 CFM rating increased by 20% to 2,640 CFM.
Additional Features To Think About
Before concluding this guide, it’s probably a good idea for the consumer to think about more than just the air cooler’s size and CFM rating. They’re probably going to want to also think about the features that can be found on the cooler. Below are some of the more common features found on evaporative air coolers that enhance the uses of the cooler or makes it more convenient to use.
- Different Cooling Speeds
- Air Filtration Systems
- Oscillating Louvres
