The Best Evaporative Coolers for Your Space

Evaporative coolers, also known as swamp coolers, are an exciting advancement in air conditioning technology that use the power of evaporated moisture to lower the temperature of the surrounding air. They can work in tandem with other air conditioning systems or as the sole, standalone cooling system in your home or room. Some even work outside to help keep you and your family cool on hot days. Although they are suited for many uses and locations, evaporative coolers perform best in locations with a dry, arid climate. Since there are so many evaporative coolers on the market today, we made this guide to showcase the best ones Amazon has to offer.

Shopping for an Evaporative Cooler

  • Cooling Power: When choosing an evaporative cooler, the cooling power (measured in cubic feet per minute, or CFM) is definitely important and should be considered along with the size of the spaces you plan to use it in. The higher the CFM, the more powerful the device and the larger a room it can fill with cool air. The bigger the room, the higher a CFM you’ll want. If you want to ensure you’re picking the absolutely perfect CFM rating for the space you want to cool, determine the square footage of the room in question, multiple it by the height of your ceilings, and then divide that number by two. The resulting number is the ideal CFM for your entire space.
  • Portability: While plenty of evaporative coolers are designed for mounting in a window or the side of your home. However, there is also plenty of evaporative coolers that are designed to be moved from room to room rather than remaining anchored in one spot. For those wanting to travel with or move around their evaporative cooler, the size and weight of it should be carefully considered. Also look for a portable model with wheels, as this makes even heavier coolers much easier to transport in between rooms.
  • Outdoor Use: Evaporative coolers aren’t just for indoor use. While not all models will function out of doors, there are quite a few that you can interchangeably use inside and outside your home if desired. Some are even designed specifically for outdoor use only. If you are going to use your evaporative cooler outdoors or in a large area, getting a model with a large, powerful fan is the best option. Look for a more portable, preferably wheeled, option if you plan to move your cooler between your home and yard quite often.
