3M Hood Assemblies and Breathing Tube

The lightweight, loose-fitting #M H-Series Positive Pressure Hoods offer easier breathing and a higher level of respiratory protection than negative pressure half and full facepiece respirators. The waterfall airflow design provides a steady stream of air into the rear of the hood, up over the top, then down into the worker’s breathing zone. Air passing across the lens reduces fogging. The H-400 Series is made of DuPont Tychem QC. The H-600 is made of DuPont Tychem SL chemical barrier fabric. All hoods are NIOSH approved.
