Abstract
A hat includes a shell, and an air filtration system for providing a protective stream of air across the face of the wearer of the hat. The shell defines an exterior of the hat. At the back of the shell is a fan housing which contains a fan and defines an interior through which air is passed through the hat. The filtration system includes a filter cartridge and a retaining basket. The filter cartridge includes a filter medium. The filter system is removeably positioned adjacent to and across the fan housing so as to filter air passing into the interior of the hat. The filter cartridge is removeably engaged to the retaining basket. The retaining basket retains the cartridge to the hat and ensures proper positioning of the filter cartridge.
