The main advantages include saving space, the possibility of permanent installation, and the ability to direct the air to specific points, such as the bed or sofa. They are also safer in environments with children and pets as they are mounted up high.

Wall fans usually have pull chains or buttons on the device to control the speed and rotation, while allowing the angle and direction of the air to be adjusted to cover a larger area. Some models also offer a remote control for greater convenience.

An air cooler uses water evaporation to cool the air, while an air conditioner uses a cooling circuit with chemical refrigerants to remove heat from the air. Air coolers are more economical and ecological, but less efficient in areas with high humidity.

Modern ceiling fans are designed to run quietly. However, the noise may increase if the installation is not correct or if the fan has worn parts.
