The Best Swamp Cooler – Comparisons and Reviews

Swamp coolers go by a lot of names. You may know them as evaporative coolers, desert coolers, or maybe wet air coolers. Whatever name you know them by, they have one purpose: to cool the air of a targeted space.

You might feel that you want to use a swamp cooler as an alternative to an air conditioner. That is a personal choice, but it’s best to be properly informed and prepared before you make that decision. There are a few things to consider about swamp coolers that will help you weigh your options, which we discuss here.

Quick Look

What does a Swamp Cooler do and how?

Just as its name suggests, a swamp cooler is meant to cool the temperature in your space during the warmer months. But a swamp cooler is neither a fan nor an air conditioner, so how exactly does it work?

Like one of the other names that they are sometimes known by, swamp coolers employ evaporative cooling in order to function. Air is cooled down through this process because heat is pulled from the air when water evaporates.

Here’s a simple way to understand how evaporative cooling works. Imagine yourself outside on a hot summer day. You spray your skin with a bottle of lukewarm water. A couple of seconds after the water hits your skin, you will experience a small chill. That is evaporative cooling!

This type of cooling generally requires very little energy. There are even swamp coolers that function without using any electricity. Talk about energy efficiency and savings!

Swamp Coolers vs. Air Conditioners

The main difference between swamp coolers and air conditioners is the way they work. As we said before, swamp coolers use evaporative cooling for their target spaces.

Air conditioners on the other hand, use vaporization and condensation of a liquid refrigerant. This requires constant energy flow and often results in a hefty electricity bill.

If you’re interested in the more long-term, budget-friendly option than you should consider looking into swamp coolers. They are known to use up to 75% less electricity than air conditioners. That is big savings.

Do Swamp Coolers Work Everywhere?

Before you get too excited about your energy savings, you first have to determine whether or not a swamp cooler is a feasible option for you. The first question is: what kind of climate do you live in?

The more humid the climate, the less effective your swamp cooler will be. So, if you live somewhere with high humidity, then you are much better off choosing a standard air conditioner for your cooling needs. If you live in a drier climate, however, you may be a good candidate for a swamp cooler!

Large Water Tank

When you have a swamp cooler, you keep it running by filling an attached water tank. The larger the water tank, the more water is held, which means a longer period of time before refilling is needed.

If you have a larger water tank, then you will be able to leave your swamp cooler running longer before needing to refill it. This can be very helpful when cooling is needed for hours at a time without interruption.

Various Fan Settings

Swamp coolers generally push their cool air around your target space using a built-in fan function. Finding a cooler with various fan settings will give you better control over how powerfully the air is spread throughout the room or space you wish to cool. This simply allows you to better customize your cooling experience.

Long Power Cord

Proper positioning of your swamp cooler can have a profound effect on the amount of cool air spread throughout your space and its even distribution. Although you may not have control over where your outlets are situated, using a swamp cooler with a long power cord will provide you with flexibility in where you choose to situate your cooler.
