Abstract (en)

[origin: EP0827702A2] A filter device (10) for a hair dryer or hot air curling brush has a filter element (12) with the inner side arranged in the air entrance of the appliance. The filter element is formed as a thin fabric or perforated foil. Contaminants such as hair and fluff are retained on the outside of the filter element positioned on the appliance to provide free access to the user. Also claimed are (i) the hair care appliance having the filter device attached to the housing (2), and (ii) a method of cleaning the filter device in which the presence of contaminants is indicated by the contrast of colour between the outside of the filter element and the contaminants, the contaminants being removed by wiping. Preferably The filter element is formed as a perforated foil or a screening fabric comprising threads of round cross-sectional area. The screening fabric is manufactured from thermosetting plastics, natural yarns, metal, a glass fabric or thermoplastic material especially polypropylene, polyacrylic or polyester.
