small box respirator CWMThe small box respirator, introduced at the end of 1916, was a great improvement on the old PH hoods the layers of which were impregnated with phenate-hexamine. A soldier breathed through the fabric and exhaled through a mouthpiece with valve. (1) The box respirator consisted of a mask attached by a hose to a filter: it was carried in a canvas haversack, and when needed, the mask could be pulled out while the filter remained in the bag.
