It won't function properly if not. So, the question is, can you use a dehumidifier with a swamp cooler? So, yes, you can surely. To increase cooling effectiveness and lower humidity, a swamp cooler can be used in conjunction with a dehumidifier.

Utilizing a dehumidifier with a swamp cooler depends on several important elements, including relative humidity, dehumidifier power, operational efficiency, and ambient temperature. Large dehumidifiers, however, emit a lot of heat energy, which can reduce the swamp cooler's ability to chill.

Keep reading this blog to know the working of both dehumidifiers and swamp coolers and in detail about their coupling, keep reading this blog!

Working Of Swamp Cooler

Swamp coolers use the evaporation principle to carry out cooling. Compared to an air conditioner, the creation and operation are much simpler. The fans draw hot and dry air. A pump draws water from a reservoir, which is then continually delivered to cooling pads. Air is forced through water-filled cooling pads by a blower fan.

Cooling occurs due to the water that air carries evaporating during flow. Therefore, cool, humid air is transported forward by the blower fan. It's the air that the swamp cooler's front end sends to you.

If you intend to use it inside, you should leave the windows and doors open, as the steady increase in humidity will make the space clammy and sticky.

Working Of Dehumidifier

Dehumidification, or the removal of water vapor from the air, is the main function of a dehumidifier. A dehumidifier is an air conditioner that uses a vapor compression cycle. The fundamental purposes of an AC and a dehumidifier are different from one another.

Although cooling is an air conditioner's primary role, it also has a secondary dehumidification function. But, the dehumidifier's primary role is to remove the air's humidity. The humidity will decrease as the room's air grows drier and drier.

Despite other factors, the way you utilize a thing is also crucial. The dehumidifier should be placed next to the swamp air cooler, with its outlet directed toward the cooler's inlet, to benefit most from this setup.

This ensures that your dehumidifier's warm, dry air can pass straight into the swamp cooler, increasing evaporation and improving cooling. To maintain proper operation, don't forget to empty the dehumidifier's water tank and refill the swamp cooler's water tank.

Since we already have a thorough Knowledge of these two appliances, let's talk about how a dehumidifier could be able to assist a swamp cooler. If there are advantages to be had from using them jointly, do so.

Boost Your Swamp Cooler's Efficiency

Again, hot, dry air is necessary for a swamp cooler to operate correctly. In other words, the swamp cooler's effectiveness will decrease if the room is damp. In humid conditions, your cooler may occasionally struggle to receive enough dry air from outdoors. In this situation, to guarantee the cooling effectiveness of your cooler, couple it with a dehumidifier.

Improve Quality Of Indoor Air

Operating a dehumidifier simultaneously with a swamp cooler at that time will keep the indoor humidity at a specific level, preventing the growth of mold and other pathogens. If you operate a swamp cooler all the time, the space may eventually become overly humid, which would be ideal for mold growth.

When we breathe these mold spores, they can seriously impact our bodies, causing congestion, breathing problems, asthma, and other respiratory problems. A dehumidifier can also help you feel cooler because sweat can drain more quickly in low humidity.

Factors That Affect The Efficiency Of The Swamp Cooler When Using With Dehumidifier

A few factors will affect its efficiency when operating a swamp cooler with a dehumidifier. In other words, you can say there are a few things to keep in mind when operating them together.


To reach a pleasant temperature, fairly high heat in your area will require relatively high chilling work from your swamp cooler. To get your chosen temperature, more cooling must be done.

Therefore, this setup won't work when the temperature is extremely high, and the humidity is relatively high.

Size Of The Dehumidifier

Dehumidifier size is still another crucial element. Dehumidifiers, as you can see, function and are built like air conditioners. By accomplishing cooling in this way, heat is released to eliminate humidity from the air.

The quantity of heat emitted by your dehumidifier's compressor will increase in proportion to its size and power. If it is high enough, your swamp cooler's ability to cool the air will be compromised.

Humidity Level In Your Region

First, examine the amount of humidity in your area. As humidity rises due to less evaporation, it will be less effective in cooling. The higher the humidity, the worse the operation of the swamp cooler. This also implies that you will require a larger dehumidifier as the humidity level rises.

Does High Humidity Affect Evaporative Coolers?

To accommodate low air humidity, evaporative coolers have been developed.

Evaporative coolers' efficiency is decreased by high humidity. The moist pads now have a higher moisture content than the surrounding atmosphere due to evaporation. Hot air is passed via wet pads in evaporative coolers to cause evaporation.

When cool air is pushed into the atmosphere from the evaporative cooler, cooling takes place. An evaporative cooler serves no purpose in an atmosphere with high relative humidity (a moisture load). It is unsuccessful.
Your evaporative cooler will experience drips due to high humidity, which will corrode the metal.

The evaporative cooler is too expensive, so it's better to use the swamp cooler when needed. If you feel the humidity level is high, switch off the device.


A dehumidifier can be used with a swamp cooler to lower humidity and enhance cooling. However, several variables affect how well the two appliances work together, including humidity and dehumidifier size.

A swamp cooler won't work correctly if humidity is quite high. While boosting the dehumidifier's output reduces humidity, it also produces more heat, which negates the swamp cooler's cooling impact.
