A headpiece (1) worn by a user provides air to the user from which airborne disease particles have been removed. The headpiece includes an air guide (2) through which air flows due to fans (13, 14). Antibacterial and/or antiviral devices (3) such as filters and ultraviolet (UV) disinfecting lights operate as air purifiers to purify air that passes through the air guide. The purified air is delivered to an area between the inside surface of a visor (10) and a face (11) of the person wearing the headpiece.
