The COMFORT ZONE uses accordion expanders that lock, and the HOLMES uses an extender screen and panel for larger windows. For placement, the COMFORT ZONE converts to a desk or floor fan on removable feet, and the BEYOND BREEZE converts to a tabletop fan on removable legs.
Speeds and motors
Speeds set the airflow choice: the Bionaire offers 3 speeds, while the COMFORT ZONE, HOLMES, and Amazon Basics offer 2 speeds each. The Amazon Basics runs a copper motor, the HOLMES runs water-resistant motors, and the Bionaire runs at 80 watts. Match the speed count and motor type to the rooms you cool.
