ASTM Level 1 Procedural Mask (50/Box)
The Canadian Shield’s ASTM Level 1 procedural masks are the standard for low-barrier fluid exposure. These triple-layer masks feature a moisture absorbent inner layer and a moisture repellent outer layer with pleated polypropylene for full coverage of the nose and mouth. Added nose stiffeners ensure a tight seal to minimize gaps.
Masks are 100% polypropylene. Latex and fiberglass free. Nose bridge is made of plastic-coated steel.
Earloops are 70% Polyester, 30% Spandex.
Our procedural masks do not contain graphene.
We put together a handy guide that can help you compare and choose the mask that best suits your needs.
