An evaporative cooler, also referred to as a swamp cooler, works by using moisture to cool the air, which is then forced out through a blower to ventilate a room or area. We carefully researched the top evaporative coolers available online by analyzing ease of use, water tank capacity, airflow quality, and overall value.

Our top recommendation is the Hessaire MC37M Portable Evaporative Cooler, which is compact, energy-efficient, and suitable for both indoor and outdoor use.

Equipped with powerful airflow of up to 3,100 CFM and large water reservoir, this functional and well-equipped evaporative cooler from Hessaire is the perfect solution to keep you cool during the hot summer months. It has a cooling media that surrounds three sides of the unit to facilitate better distribution of air. The auto-oscillation function further enhances its performance, while its versatility and portability make it ideal for both indoor and outdoor spaces.

While this Hessaire model is bulkier and heavier than other indoor or portable evaporative coolers, the four heavy-duty caster wheels make it easy to move the unit from one location to another. The 10.3-gallon water tank capacity of the cooler translates to about 4 hours of runtime. Another option is to use a garden hose and the included float valve for continuous water fill.

Bear in mind that when used in enclosed areas like living rooms, open doors or windows are required to prevent rising humidity levels. Regular maintenance, such as removing mineral build-up that can affect performance using a de-scaler, is essential to maintain the cooling pads' efficacy.
