The verdict
There is no universal winner. Choose a fan for air movement; choose an evaporative cooler only when its moisture, ventilation and maintenance requirements fit the room.
Simple air movement without refilling a tank: Electric fan
A fan circulates air without a water reservoir or evaporative pad.
Airflow passed through water: Portable evaporative air cooler
Evaporative coolers use water evaporation and can add moisture to the air.
Humid climate or limited ventilation: Electric fan
A standard fan does not depend on evaporation, while evaporative cooling is less suitable when the air is already humid.

Common questions
Questions before you buy
Is an air cooler better than a fan?
It depends on your room. A fan moves air without water; an evaporative cooler uses water and can add moisture, so ventilation and humidity matter.
Does an evaporative air cooler cool better than a fan?
An evaporative cooler can lower incoming air temperature through evaporation in suitable conditions. The result depends on humidity, airflow and ventilation; a fan alone mainly circulates air.
Can I use an air cooler in a humid room?
Evaporative cooling is less effective when air is already humid. A fan may be a more straightforward choice for air movement in that setting.
What is the difference between an evaporative cooler and a fan?
A fan moves air with rotating blades. An evaporative cooler passes air across water-wetted media, adding moisture while using evaporation for cooling.
