In 1994, we brought our O2COOL® fans to market with one idea in mind, keep consumers cool wherever they go! Here’s how it works: Misting and fanning triggers a super-cooling process. The chilling fan breeze evaporates the misted water which draws away body heat, keeping you cool longer. Whether you are at your child’s soccer game, at the beach with friends or a backyard BBQ, these personal hand-held battery-operated fans are the cool way to beat the heat.
