This is a vintage AO Safety R5700 dual cartridge respirator mask, made in the USA by the Aearo Company (Southbridge, MA). It features:

• Model: R5700

• Cartridges: AO Safety 95151A Chemical Cartridges (one on each side)

• Type: Dual filter with exhalation valve

• Condition: Pre-owned vintage condition. The mask shows minor cosmetic wear consistent with age, and the straps are intact though lightly discolored from storage.

• Note: For display, collection, or prop use only — not guaranteed safe for current industrial or protective use due to the age of the filters.

Great addition for collectors of vintage industrial equipment, safety gear, or Cold War-era items.
