This Allegro9910-D Maintenance Free Tyvek Hood is NIOSH approved. The hoods breathing tube and head suspension are completely integrated into a one piece which eliminates the need for decontamination of the breathing tube and replacement parts.

This disposable respirator hood by Allegro Safety is designed with the breathing or down tube and head suspension completely integrated so that the respirator hood assembly is constructed into a one-piece instead of the standard three-piece assembly. This eliminates the need for decontamination of the breathing tube or replacement parts, because the entire respirator hood assembly is disposed of after use. The down tube is integrated into the respirator hood, it is maintenance free and completely disposable. Offered in poly-coated DuPont Tyvek, it is flexible, splash resistant and seals in the air flow. The breathing tube incorporates a multi-layer sound dampening system made up of foam extending up inside the respirator hood that prevents the tube from being crushed or twisted during use. It allows the system to meet stringent NIOSH requirements for sound levels inside a respirator hood. The disposal respirator hood brings air down across the lens which minimizes fogging and brings air to the breathing area. A large viewing window provides a wide field of vision and its generous size makes it perfect for workers with beards or goggles. The respirator hoods large bib provides splash protection and allows it it be tucked into a suit where it directs air to the body. The disposable one-piece suspension of the respirator hood offers easy adjustment with a velcro closure and an absorbent foam headband. NIOSH Approved
