“The fiber technology featured in Fosshield® works against the types of airborne bacteria we are most concerned about. This type of ‘capture and kill’ technology is ideal. It’s the silver bullet against bacteria.”

- Dr. Charles Gerba

How is Fosshield® both Safe and Effective?

Unlike antimicrobial agents that are applied via topical chemical coatings or include actual metals, the patented, non-leaching, and non-metallic antimicrobial technology in Fosshield® is blended right into the fabric, polymer, or rubber.

As the active antibacterial agent in the SpectraShield™ 9500 N95 surgical respirator mask, Fosshield® was found to be safe when used in the breathing zone (offgassing) and against the skin (non-transdermal). The FDA tests of the mask also found Fosshield® technology to be non-leaching, while posing no risk to users or the environment.

What’s more, Fosshield® is made from Foss Manufacturing’s own Eco-fi™ fiber, which is originated from 100% post-consumer recycled plastic bottles.
