Abstract

A breathing device wall package suitable for a wall mounting comprises a filter container part having a gas filter with an inspiration opening and a suspended matter filter adjacent the gas filter with an air intake opening. A breathing mask, for example, a half mask is engaged on the filter container around the inspiration opening. A cover engages over the filter container part and encloses the breathing mask and includes a plug which is engageable with the air intake opening as well as the inspiration opening in order to close them when the cover is in position. When the cover is removed the openings are opened and the mask is immediately available for use.

Claims
