Abstract
An air escape filter apparatus for emergency use by a person comprises a filter which is contained within a filter housing which is accommodated within a half mask portion of a breathing mask which is adapted to be engaged over the nose and mouth of a person. The half mask portion includes a sleeve portion having a guide ring which engages over the filter housing and is shiftable along the filter housing while remaining in holding engagement therewith. The filter housing is of a size so that it is retainable within the half mask portion in a standby condition at which time it is substantially coextensive in length with the half mask portion so that the two elements are accommodated within a very small space. The filter is extensible at the end of the sleeve portion to free the interior of the half mask for engagement over the wearer's face in a ready condition.
