Whether you’re looking for indoor or outdoor cooling, an evaporative swamp cooler is an excellent option. These eco-friendly cooling units are ideal for use on patios, decks, garages, porches, and more.

Getting a home swamp cooler can help you to enjoy summer evenings on the porch or turn a hot basement into a usable workspace. Learn more about how evaporative coolers work and the best environments to use them below!

How Evaporative Coolers Work and Their Benefits

Home evaporative coolers work by speeding up the evaporation process in the air. Evaporation naturally creates a cooler environment, which is why you feel cooler when you sweat. The evaporation of moisture from your skin creates a cooling effect.

Home evaporative coolers use the same concept to make the air around them feel cooler. They do this by pulling the hot air through a water-saturated pad inside the cooler. The additional moisture in the air creates an effect like being lightly misted, which helps keep your skin cooler on hot days. This process can provide a cooling effect of up to 33 degrees Fahrenheit.

Most home evaporative coolers are sturdy but easy to move so that you can get the comfort you need wherever you crave it most. These types of home swamp coolers are energy-efficient and provide an excellent, cost-effective way to keep cool during the summer. Additionally, these units can be used as highly efficient fans when the evaporative setting is turned off.

Another benefit to these types of coolers is that they can help relieve symptoms of overly dry air. Some common things that evaporation coolers help to relieve are itchy eyes, dry skin, and dry/itchy throats.

Best Environment for Evaporative Coolers

Dry climates are the best environment for evaporative coolers. Locations with high humidity levels are better suited for air conditioners. At the same time, places that experience dry heat in the summer see the best results with home swamp coolers.

States like California, Arizona, Utah, Nevada, and most of the southwest are ideal environments for home evaporative coolers. These locations are known for having dry climates, so the evaporative coolers can add enough moisture to the air to create a significant cooling effect.

There are indoor evaporative coolers for cooling your sunroom, living room, or other areas of your home as long as there’s an open door or window nearby. Evaporative coolers are ideal for outdoor settings because they require a constant supply of fresh air to operate. However, the most common spaces to use a swamp cooler are in a workshop, garage, or patio. If it’s not working as expected, here are a few tips on how to make a swamp cooler colder.

Evaporative Cooler Sizing

Evaporative cooler sizing is based on CFM (cubic feet per minute of airflow). The following rates will help you see what size of home evaporative cooler you will need for your space.

· 0-200sqft = 250-750 CFM

· 251-500sqft = 751-2,000 CFM

· 501-1,000sqft = 2,001-4,000 CFM

· 1,001-2,000sqft = 4,001-7,500 CFM

· Over 2,000 sqft = 7,501+ CFM

There are a few reasons you’ll need to increase these rates. Generally, if you have ceilings over 8ft tall, the space is in direct sunlight, or there will be a lot of traffic through the space or appliances creating heat, you’ll need to size up by 20%.


Another benefit to these types of coolers is that they are very low maintenance. It’s easy to keep up with the regular maintenance of a home swamp cooler. The exterior needs to be wiped down with a wet cloth and dried. Inside, the water tank and pads can be cleaned with water and vinegar to deodorize and clean. If there is any mildew build-up on the pads or interior of the cooler, simply spray with a disinfectant spray and clean as usual.

When the summer is over, and you’re ready to store the home evaporative cooler for the winter, drain the tank and clean the tank and pads as usual. Once the unit is clean, run the fan-only setting for half an hour to ensure it is completely dry before storing.


A home evaporative cooler is an excellent choice for keeping your home, garage, or patio cool during the summer. These energy-efficient coolers are a cost-effective way to keep your indoor or outdoor spaces cool, as long as there’s a constant supply of fresh air.
