Our #350-A is a NIOSH approved 3M™ Half Facepiece Respirator which is molded in comfortable silicone, and features a four point cradle suspension which won't slide down the back of the head. The low profile design keeps cartridges out of field of view and permits glasses or goggles to be worn. We supply the mask complete with headgear, one pair of organic vapor cartridges, and one pair of prefilters so it is ready to be used right out of the box.
