A sleep mask valve structure for treating a patient suffering from obstructive sleep apnea is provided. The valve structure includes a rigid valve housing comprising an inspiratory valve and an adjustable expiratory valve. The housing defines an outside mask side and an intra-mask side, and further defines an expiratory airflow conduit accommodating airflow from the intra-mask side to the outside mask side and an inspiratory airflow conduit accommodating airflow from the outside mask side to the intra-mask side. The expiratory airflow conduit includes at least two changes of direction, with each direction change greater than or equal to 75 degrees, and the inspiratory airflow conduit includes at least one change of direction greater than or equal to 75 degrees. The two paths share at least one change of direction.

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.

A hard hat with air flow system includes a hard hat with an air flow passage for passing air through the hard hat and out exits ports at the front of the hat to provide a shield of air downward across the face of a user. The system includes an air filtration system, a blower assembly for drawing air through the air filter and pushing the filtered air into the air flow passage of the hard hat, and a power supply for powering the blower. The filtration system, blower assembly and power supply being supported on a harness such as a belt or backpack, external from the hard hat.
