The FDA-required tests of the SpectraShield™ 9500 N95 surgical respirator mask confirmed Fosshield® technology to be non-leaching, while being safe for users & the environment. The Fosshield® silver & copper ions bind to any microbes that may be present on the fiber & disable their critical functions.
The safe, clean, and natural antimicrobial properties of silver and copper are built right into each product protected by Fosshield® without using synthetic or chlorinated chemicals. Fosshield® is also used in the FDA cleared SpectraShield™ 9500 N95 surgical respirator mask. Fosshield® incorporation was found to be safe when used in the breathing zone (offgassing) and against the skin (non transdermal). The FDA-required tests of the mask confirmed Fosshield® technology to be non-leaching, while being safe for users and the environment.
The key to the effectiveness of Fosshield® is the unique combination of silver and copper ions, which are incorporated into the fiber and naturally attack the microbes. The Fosshield® ions bind to any microbes that may be present on the fiber and disable their critical functions (metabolism, respiration, and reproduction).
