Definition & Meaning of "air cooler"

What is an "air cooler"?

An air cooler is a device that cools the air by evaporating water. It works by drawing warm air through a wet filter or pad, which cools the air as it passes through, and then blows the cooler air back into the room. Air coolers are energy-efficient and eco-friendly compared to air conditioners, as they use less electricity and do not require special cooling chemicals. They are ideal for dry climates and can help reduce the temperature in smaller spaces. Air coolers are portable and often used in homes or offices to provide a cost-effective cooling solution.
