About this technology
Overview
The Smoke Mask, Inc. (SMI) personal escape hood and Guardian Filtration System provide respiratory protection that enables people to escape from hazardous and unsafe conditions. The breathing filter technology utilized in the products is specifically designed to supply breathable air for 20 minutes. A patent license from NASA allowed SMI to utilize a low-temperature oxidation catalyst in its protective breathing filter. The catalyst converts carbon monoxide to non-toxic carbon dioxide at room temperature, as well as oxidizes formaldehyde fumes, carbon dioxide, and water. SMI products are designed for emergency use at home, work, and school, as well as for professional firefighting and rescue efforts.
