Especially comfortable for bearded workers, the hood style respirator is lightweight and loose-fitting, to fit comfortably over the head. A large clear window offers a wide view and complete protection in dirty environments such as spray painting or asbestos abatement. The convenient disposable design is perfect where respirator cleaning or decontamination is difficult, just remove the down tube and clamp before disposal. Includes OBAC quick connects. For convenience, each replacement hood comes complete with a hood harness. NIOSH approved.
