Abstract

Respiration protection mask has the spaces in front of the nose and the mouth, respectively, separated so that expired air is completely separated from air breathed in. Preferably the eyes are in the breating space, preventing fogging of the window. The nose and eye space is sealed off by a soft, porous plastics foam strip which also acts as a filter, from the outer air. The mouth space is the free ambient air. The inspiration space around the nose and eyes may be completely sealed, and connected to the ambient air by a filter. Each space may have a non-return valve.
