How to choose
Airflow and speeds
Airflow in CFM sets how much air the fan moves, and speed settings set how finely you control it. The KEN BROWN delivers up to 4,700 CFM and the MAN moves 3,500 CFM. The Genesis runs 3 speeds, and the Vornado adds variable speed control. Compare the CFM figure with the control range before choosing.
Tilt and placement
Tilt sets where the air goes, and the base sets where the fan sits. The MAN head tilts up, down or straight ahead, the KEN BROWN tilts 360 degrees, and the Vornado kickstand adjusts airflow vertically. All four are floor fans, so match the tilt range to the spot you want cooled.
Noise and upkeep
Noise sets whether the fan suits a bedroom, and the grille sets how cleanup goes. The KEN BROWN runs below 60 dB even at full speed, and the MAN low speed suits quiet rooms. The Vornado removable grille makes cleaning easy. Check the noise figure and the grille before choosing.
