Keeping cool in a dry climate can be challenging, and typical air conditioners may not be adequate. You may believe that the only alternatives for cooling your home during the summer are an air conditioner or a box fan, but there is a third option: an evaporative cooler. 

The best evaporative cooler can fix that problem because it can do things that an air conditioner can’t and is far less expensive to run.

Evaporative Coolers: What Are They?


Evaporative air coolers use the power of evaporation to chill the air. Water goes from a liquid to a gas when it evaporates. As a result, the water’s highest-energy particles escape first, causing a temperature reduction. 

This is why, on a hot day, a moistened towel on your forehead feels cool — the water evaporates, lowering the temperature of your head.

When it comes to the air in your home, the same logical principle applies to evaporative cooling. Evaporation can assist lower the temperature of the air in a dry area.

If you’ve ever misted the air around you so you can feel cooler on a hot summer day, you’ve probably experienced this. An evaporative air conditioner works on the same principle as a traditional air conditioner. 

It incorporates technology to make the process more efficient — and less dirty — than just spraying a room with water and hoping for the best.

How Do Evaporative Coolers Work?

Basic evaporation is automated in an evaporative cooling system to efficiently lower the temperature of the air in your home. 

A fan, a thick pad, a water reservoir, and various extra controls for fine-tuning the outcomes will make up the machine in general. The machine draws dry, hot air and across the cooler pads by the fan.

These thick pads absorb water from the reservoir and are made up of multiple layers to maximize surface area. The water molecules on the surface of the pad evaporate as hot air passes over them, causing the air temperature inside the cooler to drop by as much as 20 degrees. 

On a hot day, the fan then delivers that chilly air into your room, where you may enjoy the coolness.

Some evaporative coolers also contains other helpful components Many people use air filters and pads to enhance air quality by lowering allergens and preventing mildew growth, which is especially helpful for people who suffer from allergies or other respiratory problems.

While not technically necessary, a water pump can help to speed up the absorption into the cooling pad. Some models allow you to add an ice pack to cool the air the fan blasts into the room even more. A remote control, variable fan speeds, and oscillating functions are additional essential features.

Best Evaporative Coolers 2021

Unless you live in a consistently humid region, evaporative coolers is all you need: you can significantly cool your personal space while not relying on the comfort of others. 

As a result, we’ve put together a list of the top portable evaporative cooler models for 2021.

#1 Hessaire MC18M Portable Evaporative Cooler


The Hessaire MC18M is a small evaporative cooler that can handle up to 500 square feet of outdoor space and outperforms some of the larger coolers on the market. 

While it has a lot of cooling power, Hessaire contains a small tank and will need to be refilled after three to four hours of continuous operation without a hose.

It’s great for outdoor use or bigger indoor spaces, and it includes a number of portability characteristics that make it one of the best portable swamp coolers for transferring from one location to another.

Hessaire MC18M Portable Evaporative Cooler CFM 


The Hessaire MC18M, which represents the small side of evaporative coolers, boasts 1300 CFM, estimated at 115.41 square inches (0.80 square fee). The actual airflow at 808 CFM on high with an average airspeed of 1009 feet per minute (11.47 MPH). It, like its big brother, falls short of its advertised value by a significant margin – about 500 CFM, or 38% in this case.

Convenience and Effectiveness

The Hessaire MC18M model has a simple control panel with only one rotary switch and three motor speed modes: low, medium, and high. A pump switch, as well as a center rocker switch for fan oscillation and a power switch, make it simple to regulate the pump.

The MC18M is extremely light and portable, allowing you to move it around your home and property with ease.Included are 4 heavy-duty wheels, an ergonomic top handle, and a float valve for a garden hose connection. 

The Hessaire MC18M, like most good swamp evaporative coolers, is also good to use both indoors and outdoors and works best when the air humidity is low.

Energy Efficient

In this portable swamp cooler, Hessaire has put a lot of emphasis on performance and energy economy. It makes use of high-density XeL50 media, which has 80 percent more evaporation surface than ordinary density evaporative material and, when combined with a three-sided pad intake area, greatly improves its cooling capability.

From a power standpoint, the Hessaire MC18axial M’s propeller allows it to throw cool air longer while remaining energy efficient. This swamp cooler, in fact, has one of the best cubic feet per minute (CFM) to dollar ratios.

Also Best for Outdoor Environments

While Hessaire notes that this device is best suited to outdoor environments, it can also be utilized in well-ventilated indoor environments. If you do use it indoors, keep in mind that it has enough power to chill a couple of rooms, but the high airflow rating of 1,300 CFM may be too much for a tiny area.

This swamp cooler is built of robust yet lightweight ABS resin, making it very easy to move from spot to spot to cool any place you’re in. It also has a compact design, robust wheels, and a carry-handle.

What to Look for When Buying an Evaporative Air Cooler

When buying evaporative air coolers, there are a few things to keep in mind. Below, we’ve included all of the critical variables to consider when comparing and contrasting various models in order to select the best one for your needs.

Cooling Area (CFM): 

When purchasing an evaporative cooler, the size of the cooler/cooling area is critical to consider. This will tell you whether the cooler is capable of successfully cooling the room. You’ll need to check the cooler’s CFM for this. 

Evaporative air coolers are measured in Cubic Feet per Minute, similar to how air conditioners are measured in BTUs (CFM). This is the amount of air that a given cooler process can handle.

Here is the formula used to calculate the right CFM, based on your room size.

Room’s Square Feet X Ceiling Height / 2 = CFM.

Water Tank Capacity

 Are you tired of continuously replenishing the water tank in an evaporative cooler? Then simply choose coolers with sufficient water tank capacity. For example, a swamp cooler will run all night/day with a tank capacity of at least 5 gallons of water. 

A smaller tank containing 1–3 gallons of water, on the other hand, will last 5–7 hours. The water from the tank is used by a chiller based on its CFM.

Power Consumption

While purchasing an evaporative air cooler is a one-time investment, the ongoing costs are a significant one. If you run across two air coolers with identical features but differing power ratings, choose the one that consumes less power, regardless of price.

The power consumption of a given model is determined by the amount of area you want to cool. A general guideline is that as the cooling area of a cooler grows, so does the power consumption of the cooler.


The greatest swamp coolers are those that are easy to transport and move about. They are wheeled and have a light but strong body. Most of these types can only handle one room at a time, making portability a must-have feature for these coolers.

Final Thoughts

We hope you enjoyed this list of the best evaporative air coolers and found it helpful in deciding which air cooler would be ideal for your home. Almost all of the devices on our shortlist consume very little electricity while providing excellent cooling. 

Even yet, if you’re having difficulties deciding, we have a few personal recommendations for you:

  • The Hessaire MC37M Portable Evaporative Cooler is the only name that springs to mind when it comes to a strong air cooler. It has a number of variable speed and cooling modes, and it can cool an area up to 950 square feet. As a result, it can be used both indoors and outdoors.
  • If you’re concerned about power consumption, the BREEZEWELL 2-In-1 Bladeless Tower Fan uses only 65 watts and is one of the most energy-efficient evaporative coolers for indoor use. Despite its low energy usage, it has a cooling capacity of 900 square feet, which is rather outstanding.
