The major advantage that evaporative coolers have over traditional AC units is portability. Window and wall mounted air conditioner units are limited only to a single room. By contrast, evaporative coolers can be easily rolled from room to another along caster wheels. Another advantage of evaporative cooling technology is that it only uses water and does not produce any other by products such as gases and heat. Evaporative coolers are available in various sizes designed to cool off small spaces to an entire level of a home. It is recommended that an air filter such as HEPA be installed into an evaporative cooler.

Evaporative coolers, or swamp coolers, work best in hot and dry climates rather than humid ones, as they rely on the evaporation of water to cool the air. In a hot climate, the low humidity allows more water to evaporate, which cools the incoming air effectively. However, in humid conditions, the air is already saturated with moisture, reducing the evaporation rate and the cooler's efficiency. Therefore, while evaporative coolers can still function in humid climates, their cooling effectiveness is significantly diminished compared to drier environments.
