Technology & Innovation

Pioneering next-generation antimicrobial protection with SpectraShield™ and Fosshield® fiber technology.

Core Technology

SpectraShield™ Technology

The SpectraShield™ GUARDIAN

The SpectraShield™ GUARDIAN is the first-ever REUSABLE antimicrobial-protected N95 respirator mask. FDA-cleared for 8-hour extended use with continued evaluation for additional extended-use applications, it is engineered with next-generation microbe-fighting technology and designed to be reused for up to 28 days. Made in the USA with domestically sourced materials.

Fosshield® Fiber Technology

Raw materials under exclusive license made in New Hampshire, USA. Fosshield® fiber is the first and only antimicrobial fiber successfully embedded with a natural balance of silver and copper. It is the first to ever receive FDA and EU (CE Mark) clearance for use in a medical device.

Advanced antimicrobial fiber technology

How It Works

Its proprietary, safe, natural, and effective Fosshield® antimicrobial technology penetrates the microbe's cell wall, attacks its metabolism, and disrupts reproduction. The patented technology, which embeds a non-toxic silver and copper zeolite into a fabric's fibers, ensures protection for individuals from infectious disease but also for mitigating the spread of disease.

Proven Science

Antimicrobial Properties

Centuries of Use

Silver has been used for hundreds of years to prevent infection, providing a proven foundation for our antimicrobial technology.

Multiple Mechanisms

Multiple antimicrobial mechanisms work in concert to neutralize pathogens at the cellular level.

Low Resistance Potential

Low potential for microbes to develop resistance, ensuring long-term effectiveness of the technology.

Synergistic Effect

Silver and copper have a synergistic effect, amplifying antimicrobial performance beyond what either metal achieves alone.

Highly Antifungal

Copper provides highly effective antifungal properties, broadening the spectrum of protection.

Broad-Spectrum Efficacy

Effective against 650+ strains of bacteria and fungi, and inactivates SARS, Norwalk, and H5N1 viruses.
