No one likes feeling hot and sweaty; however, ending up with an inflated electricity bill can be worse.

For most people, hot summers mean air conditioners running constantly in their homes and offices. That said, dealing with elevated energy costs can make you wary of overusing the AC. You might be wondering if there is a better way to deal with this persistent issue.

Well, we’re glad to tell you that there is! Consider purchasing an evaporative swamp cooler. These machines efficiently suck hot air from a room while using a water tank and pump to evaporate most heat. Once the air cools (and drops by almost 15 degrees), it is thrown back into the room, causing a humidifying effect.

This effect is excellent for places that experience dry heat. Moreover, the energy costs are lesser compared to that of air conditioners and box fans. In this guide, we will tell you about our top 11 recommendations for the best evaporative swamp coolers.

Let us begin, shall we?

Moving on, the front design features adjustable louvers that you can manually move up or down to adjust the airflow according to your needs. It has an excellent air flow capacity of 1,300 CFM and has a simplistic operation that is user-friendly and intuitive. Furthermore, its five modes can be adjusted with an easy-rotate knob, which is excellent.

Although you need to keep an eye on the water tank level and refill it continually, the Hessaire makes it easier to do so. Select the Continuous Fill feature and allow the tank to fill up automatically when it requires water. The manufacturers have provided a float valve and brass float adapter that enables you to control the water level without frequent monitoring.


What Could’ve Been Better?

The round control knob is easy to use and features a simple design, but we did not like its build quality. Unfortunately, it feels like cheap plastic and is slightly flimsy. If it isn’t handled with care, it may break off, which is not expected of any product.

  • 2 unlocking & 2 locking wheels
  • Excellent water level indicator
  • Only fan option
  • Availability of colors
  • The round controller switch is flimsy

Next, this cooler can be conveniently controlled with a remote control, eliminating the need to get up to turn it on or off frequently. Moreover, the remote control has fantastic features like a timer, three setting modes, and swing mode. This makes controlling the machine simpler and more convenient than manual controls.

Moving on, an active carbon filter on the front efficiently traps dirt, contaminants, as well as bacteria and germs. The filter can be detached for cleaning, so you don’t need to worry about dust collection.

Finally, the included water tank is also detachable, enabling you to remove it easily for filling with water or cleaning periodically.


What Could’ve Been Better?

Overall, this cooler worked fantastically for all our needs. Our only gripe with it is that the fan can be quite loud, especially on its highest setting. However, this sound is the most apparent only at nights when the surrounding area is relatively silent.

  • Remote control features
  • Wheels for easy transportation
  • Detachable active carbon filter
  • Lightweight and portable

  1. Luma Comfort Evaporative Air Cooler

The evaporative swamp cooler from Luma measures 35.35″ in height and 15.65″ in width, making it perfect for most indoor spaces. It has a tower fan design with four wheels that make it easy to transport without hassle. Moreover, its remote control feature makes operating and controlling the machine a breeze.

Another excellent aspect of the Luma is that it is eco-friendly and safe to use. This machine does not use chemicals such as Freon, which many competitor products do. It helps you achieve a clean and cool environment in your home without using harmful chemicals, which is fantastic for those who are environment-conscious.

The removable 1.5-gallon water tank is easy to clean and maintain over time. Moreover, you can easily detach it to fill water as required. You will also find a timer that enables you to add pre-set customized options to turn on and off the cooler.


What Could’ve Been Better?

The only drawback we noticed was a loud, annoying beeping sound that alerts you when the cooling feature is turned off and the fan is automatically turned on. It is still tolerable during the daytime; however, the multiple beeps can be annoying to deal with during the night.

  • Included remote control
  • Saves energy costs by 75%
  • Three fan speeds with oscillation
  • Removable water tank
  • Loud, multiple beeps when the cooling feature turns off
  1. Hessaire MC37M Evaporative Cooler

Furthermore, it has two models with varying air flow capacities that give you more options to choose from according to your needs.

Why Did We Like It?

Those looking for a swamp cooler that covers a larger area can consider this model for their needs. It efficiently covers an area of 950 square feet while providing 3,100 CFM of air flow capacity.

Moving on, the machine weighs 39 pounds, which is relatively higher than competitor brands. However, it features four heavy-duty wheels, which make transportation a breeze.

If you’re tired of dealing with coolers that need to be frequently refilled, this one offers a Continuous Fill option that you can utilize. Attach any regular household hose to the float adaptor to enable this, and you won’t need to worry about continual manual refiling.

Coming to its cooling capacity, you will find multiple three-sided cooling pads which are highly rigid. These provide a larger cooling area that enables more evaporation, providing you with cooler air for your home.


What Could’ve Been Better?

In our opinion, this model can be slightly bulky and cumbersome for some users. However, its wheels make it easier to transport without hassle. Furthermore, it does not come with a remote control feature, so we needed to manually turn on and off the machine and change its controls using the switchboard.

  • Both manual and continuous fill options
  • Included cup holder design
  • Four heavy-duty locking wheels
  • Pump switch
  • Increased surface area for higher evaporation
  • No remote control option

Lastly, this product is an excellent choice for most homes and offices as it uses eco-friendly technology. Those who are environment-conscious will appreciate using nontoxic elements to evaporate heated air instead of using chemicals.


What Could’ve Been Better?

Initially, we faced minor issues where the cooling modes would turn off automatically before long. We looked at the owner’s manual for instructions, but it was quite unclear.

After going through a dozen customer reviews, we found some excellent advice, stating that we had to fill the water container with ice first. The gaps then could be filled with room temperature water. The manufacturer’s instructions should have been clearer to help its users.

  • Environment-friendly technology
  • Three cooling modes and fan speeds
  • Water level indicator
  • Remote control feature
  • Customizable timer option
  • Unclear manufacturer’s instructions
  1. Honeywell CL201AE Evaporative Cooler

Moving on, it comes with a fantastic active carbon dust filter that automatically traps pollutants, contaminants, dust, dirt, and bacteria. You can conveniently remove this dust filter to clean it periodically, ensuring there is always a steady flow of safe, clean air at home.

We also appreciate the addition of an ice compartment which is excellent for producing cool air. Furthermore, it features a low water level alarm that alerts you when it’s time to refill the water tank. You can also control all its features and settings conveniently using the remote control.

Finally, we loved the adjustable humidifier option that gives us the luxury to choose the humification level we want in the room.


What Could’ve Been Better?

It is vital to keep a close eye on the floater when filling the water tank. Several instances have occurred where users would overfill the water tank (or underfill it), causing issues with its usage.

The manufacturer’s instructions are not very clear, so check out some customer reviews or videos to know the right way to fill the water tank.

  • Integrated hostler for the remote control
  • Programmable timer
  • Wide opening for easy refilling of the water tank
  • Heavy-duty wheels for transportation
  • Unclear instructions on how to correctly fill the water tank
  1. ComfyHome Evaporative Air Cooler

Moving onto our next recommendation, we have the ComfyHome Evaporative Air Cooler. Although it is a tower fan, it has a unique design that enhances its modern appeal and makes it perfect for most homes. It features four modes and has several added features, which make it an extremely popular choice.

No products found.

Why Did We Like It?

One of the best aspects of this product is that it is a cooler and humidifier in one. It features four separate modes – normal, cooling, sleep, and natural. Moreover, you can choose between three fan speeds for ultimate comfort. You also have the option of changing the controls using a remote or doing it manually.

Moving on, we want to talk about its unique design. Unlike other coolers, this one is exceptionally straightforward and manageable to clean. The blades do not need to be removed, and you can insert your hand into the round gap of the tower to clean it with a damp cloth.

Since it has a special sleep mode, you may be wondering how loud the fan is. Well, the fan produces less than 42db, enabling you to continue with your daily activities without interruption. Furthermore, it isn’t loud enough to disrupt your peaceful sleep during the night.

What Could’ve Been Better?

The machine has an easy-grip handle located at the back to enable convenient transportation. Although we loved the addition of this handle, the absence of wheels can make it slightly challenging for some users to transport it. In our opinion, adding wheels would have made the machine easier for transportation.

  • Humidifier adds moisture to a dry room
  • Ultra-quiet operation
  • Manual and remote control features
  • Lightweight and compact design
  • Absence of wheels for easy transportation
  1. Costway Evaporative Swamp Cooler

For our next recommendation, we want to introduce the Costway Evaporative Swamp Cooler. This product features three wind speeds and three modes, giving you adequate options for your comfort. Plus, the 7.5-hour timer is excellent for those who want to use it during the night but don’t want to worry about when to turn it off.

No products found.

Why Did We Like It?

Those looking for a lightweight swamp cooler with excellent features and easy transportation will appreciate this product. The evaporative swamp cooler from Costway features a large 8L water tank, three modes, and three speeds. Moreover, you can use it without water as a regular fan, so you have the choice not to add water.

Next, we liked the 7.5-hour timer, which is fantastic for those who want to enjoy an undisturbed sleep cycle without worrying about the cooler. You can customize the timer to turn on or off as per your requirements.

We also appreciate the built-in handle and four heavy-duty wheels that make transportation a breeze. Not to mention, the product is incredibly lightweight, weighing only 13.5 pounds, so maneuvering it is not challenging.

Lastly, we want to talk about its 70-degree automatic oscillation feature. This is fantastic for cooling an entire space rather than simply spot cooling an area.

What Could’ve Been Better?

The sleep mode feature on this cooler is not very effective, at least in our experience. The fan speeds frequently change, which can create a bit of noise. Although this isn’t apparent during the daytime, if you’re sleeping in a particularly quiet room or are a light sleeper, the sound may disrupt your sleep.

  • Integrated handle and wheels for easy transportation
  • Anion feature for fresh air circulation
  • Humidifier and cooler in one
  • Low power consumption
  • The sleep mode has frequent fan speed changes, which can be noisy

Moreover, it offers four fan speeds and various cooling modes to help you create an ideal atmosphere in your home.

Why Did We Like It?

We want to begin by talking about the extra-large form factor of the Ivation Evaporative Cooler. At 36.2 pounds, this cooler has a 6.9-gallon water tank capacity which runs for hours without interruption. That said, it features energy-efficient technology that ensures that your energy bills do not skyrocket.

Furthermore, it comes with a remote control that enables you to change the settings without getting up from your comfortable spot. You will also notice a low-maintenance reservoir that can be filled from the top or bottom, depending on your convenience. 

Wondering how to find out when the water level runs low? Take a look at the integrated water level indicator, which alerts you when the water tank requires refilling. 

What Could’ve Been Better?

Although this large evaporative cooler is excellent for large spaces, it is not entirely portable. This is primarily due to the lack of integrated handles or wheels, making transportation slightly problematic for users. 

As such, we recommend choosing a spot for it in your home where it will not be disturbed.

  • Integrated water level indicator
  • Energy-efficient technology
  • Built-in 8-hour timer
  • Remote control option
  • Not portable (no wheels or handles)

Next, you also have the continuous water refill option. Essentially, this eliminates the need to worry about refilling the water tank as it automatically refills when needed. It also features adjustable louvers that you can manually move to change the air flow direction.

We also want to talk about its weather-resistance capabilities. As such, this machine stood the test of time and adverse weather conditions, making it ideal for outdoor use.


What Could’ve Been Better?

Overall, this product is excellent for heavy-duty outdoor use. However, our only gripe with it was that it does not feature a remote control. Moreover, since the machine isn’t lightweight (weighing 60 pounds), the addition of a handlebar or integrated handle would have made transportation much more manageable.

  • Long electrical cord with storage option
  • Ideal for outdoors and large spaces
  • Ultra-wide fan blades
  • Ice tray feature for cooler air output
  • Weather-resistant
  • No handle for easy transportation
  • Absence of remote control

Are you tired of breathing in warm, unpleasant, or stale air in your small space? Well, consider installing the DeLonghi Swamp Cooler. This machine weighs only 16.22 pounds, making it super lightweight. However, the addition of four heavy-duty wheels is what makes transportation a breeze.

Moving on, you will find a pleasant LED display that shows you essential information about the machine and its settings.

One of the best aspects is its 24-hour timer. Unlike other competitor products, the DeLonghi features an around-the-clock timer that is convenient for all lifestyles. It also features a 4.5 L water tank which is super easy to refill and clean as required.

Finally, you will find three fan modes and speeds to choose from, along with easy-to-adjust louvers that let you change the direction of airflow easily.


What Could’ve Been Better?

We loved the lightweight and compact design of this cooler and the heavy-duty wheels that are essential for transportation. That being said, the absence of an in-built handle made transportation slightly challenging, as we had to hold the top of the machine or push it, which can lead to injury or accidents.

  • 24-hour timer
  • Quiet operation
  • 1-year warranty
  • Remote control feature
  • No in-built handle for easy transportation

Buyer’s Guide

With that, we have come to the end of our recommendations. Now that you know about the best evaporative swamp coolers in the market, have you decided on the right one? If not, don’t worry. We have included a short guide to help you choose the right product for your needs.

So, let’s get right to it.

  1. Water Tank Capacity

An essential factor to consider when purchasing an evaporative swamp cooler is its water tank capacity. The higher its capacity, the lesser you need to refill it. Moreover, a larger water tank will typically run for longer hours than a smaller one.

That said, you should check whether the product comes with a manual or continuous filling option. In the latter case, the tank capacity will not matter much as it will refill automatically when it is running low.

  1. Size

Depending on your needs and purpose of use, it is vital to check the size of a cooler before purchasing. In case it is too large or heavy, you may not be able to move it up and down the stairs (if the need arises). However, the addition of heavy-duty wheels will make transportation easier, so look out for those.

  1. Remote Control

If you are looking for convenience, it is best to opt for a cooler that includes a remote control. Without this, you are left to manually switch it on and off and change controls, which can get annoying after a while.
