How to choose
Speed settings shape the sound
A fan with several speeds lets you pick a low hum or a stronger rush, and every pick here has 3 speeds except the Vornado Model 80X, which has 99 speeds. A lower speed gives a softer background sound, while a higher speed moves more air. Compare the speed count with the airflow figure, such as 1,710 CFM for the Generic 20 Inch Box Fan, 1,200 CFM for the BLACK+DECKER 20-inch fan, and 640 CFM for the EZ-CHILL 20-inch fan.
Compare airflow and noise figures together
Airflow in CFM shows how much air a fan moves, and the noise figure in db shows how loud it runs. The Generic 20 Inch Box Fan gives 1,710 CFM at 55 db, the BLACK+DECKER 20-inch fan gives 1,200 CFM at 63.3 db, and the EZ-CHILL 20-inch fan gives 640 CFM at 52 db. A higher CFM figure does not by itself mean a better background sound, so weigh both figures against the room where you will place the fan.
Placement and upkeep for steady sound
Place the fan on a flat floor, table, or windowsill where air can move freely, and keep the cord out of walkways. Fans with a carry handle, such as the Generic 20 Inch Box Fan, the BLACK+DECKER 20-inch fan, and the EZ-CHILL 20-inch fan, move between rooms with less effort. The Vornado Model 80X has a removable grille, which helps with cleaning the grille, and a kick stand lets you adjust airflow direction.
