Spot coolers are more compact air coolers, or swamp coolers, that are designed to cool the immediate area around the cooler. Room coolers are larger in size and provide more powerful air flow ideal for cooling larger spaces such as living or dining rooms. Outdoor coolers are UV & weather resistant with large water tanks and ultra-powerful airflow, making them ideal for cooling outdoor areas such as your patio or backyard.
Find out the airflow of your air cooler
Look at the CFM (Cubic Feet per Minute) or m3/hour rating of the air cooler. These tell you the amount of air that passes through the air cooler per minute (or hour). The higher an air cooler’s CFM or m2/hour rating, the faster it moves the air, providing wider coverage for the space you want to cool.
The water tank capacity does not necessarily dictate the cooling performance of the air cooler however, it affects the time you need to refill the tank and the physical size of the cooler. Smaller water tanks may physically fit better in smaller rooms. Some room coolers and outdoor coolers have a built-in continuous-water supply connection that allows you to connect with your home’s water hose for continuous tank refills. You can find a simple guide below for choosing an air cooler based on tank size.
