Note: Box Fans and other fans, in general, do NOT decrease the temperature of the air they blow/exhaust - cooling is done by the evaporation of the moisture from human skin, which is more intensive as the air passes faster over the skin. Most popular box fans are smaller 7-10 inches units that are used as personal cooling devices - such units are usually placed on the flat surface near the person, usually on the desk, and larger 18-20 inches box fans that are placed usually on the floor and keep even larger rooms cooler and more pleasant to be in. Since box fans may operate for hours, day after day, many people wonder how much does a box fan cost to run.
