Table fans rest on a table, desk, shelf or other flat surface and have the advantage of being extremely mobile and convenient. They can provide a lot of power in a small area and are much handier than pedestal fans.
Table fans come in all sorts of sizes, too, even in designs that are just several inches tall and can keep you cool at your desk all day. These fans are the ultimate in convenience and personal cooling.
They are not a good choice if you have a large area that you want to cool.
