Open Air Cooler: What the Term Means Before You Buy

The wording is not a single technical category. Verify whether the product uses evaporation, refrigeration or only fan airflow.

Direct evaporative systems need an air exit path; follow the product manual for window or vent positioning.

Coverage depends on technology and airflow. Check manufacturer room guidance instead of inferring capacity from the label.

Evaporative cooling is less effective in humid air because less water evaporates. Consider local climate and operating limits.
