Powered air-purifying respirator draws air through high-efficiency cartridge and blows up to the butyl rubber hood through a flexible breathing tube. Air then travels across open space at top of hood, down over wearer's face, and out at the base of cape. NIOSH CBRN-approved models 19-167-756 and -757 are recommended for use by first responders, law enforcement, military and healthcare professionals needing protection from or responding to natural disasters or acts of terrorism.
