Tower fans are becoming increasingly popular. They feature multiple fans and blades in a single unit. Unlike pedestal fans, they take much less space. They have rotating bases and inlets on the sides that pull in air.
As opposed to a pedestal fan, the airflow from tower fans covers a wider area. This is because they blow out air from top to bottom. Pedestal fans have a stand attached to the fan. So the air goes in the direction of the fan.
That said, pedestal fans may be more powerful than tower fans. However, newer tower fan models are featuring better blades and advanced technology. They could soon be just as powerful as pedestal fans
