Breathing zone arrangement

A breathing zone arrangement comprising at least one air flow generating device (4) structured to generate a defined air flow through at least one air flow outlet into at least one air flow conduit (8), at least one filter arrangement (10) configured to receive air generated by said at least one air flow generating device (4) via said at least one air flow conduit (8) and to filter received air, an air guiding device (12) configured to receive filtered air from said at least one filter arrangement (10) via said at least one air flow conduit (8), wherein said air guiding device (12) is structured to define a breathing zone space (14) provided in front of the mouth of a user (16) when said air guiding device (12) is mounted in front of the user (16), wherein said breathing zone space (14) has a predetermined volume and an extension large enough to cover the mouth of the user (16). The air guiding device (12) comprises an air flow distributor member (20) configured to distribute said filtered air flow into two essentially perpendicular and laminar air flows wherein said predetermined position immediately in front of the mouth allows one air flow (22) to be directed towards and confined to the mouth and the other air flow to be directed towards and confined to the nostrils. Thereby no sealing is required between said air guiding device (12) and the user (16).
