Air Cooler at Home: Choose for Your Room

An air cooler at home is most useful when the room can exchange humid air with the outdoors and the climate is not already very humid. Decide whether you want a personal breeze or airflow across a larger space; these are different jobs. Start with room size and climate. Evaporative cooling adds moisture, so it is generally better suited to dry conditions with ventilation. Check airflow, intended coverage, water refill and cleaning instructions. For closed or humid spaces, compare a fan or air conditioner.
