摘要：
A respirator includes an outer mask defining a first volume. An oronasal mask defines a second volume. The oronasal mask is positioned within the first volume. A primary filter is affixed to the outer mask and a secondary filter is positioned within the first volume such that the secondary filter filters air traveling from the first volume to the second volume. The secondary filter filters air traveling around a portion of the second volume. The filters are arranged to filter either particles or vapors, or a mixture of these, as required.
