Oxafence Active Protection Has Arrived

It’s time for masks to kill viruses*

The FDA-Cleared ProGear Surgical Masks with Oxafence are available NOW – it’s the protection healthcare workers and patients deserve.

*Inactivation of the following test virus single isolates after five minutes of contact with the treated surface of the mask in laboratory tests in 500 ± 25 lux: 99.9% of Influenza A/PR/8/34/H1N1, 99.99% of Betacoronavirus 1 OC43, and 99.99% of Feline Calicivirus F-9. Antiviral efficacy on other viruses and correlations between in vitro testing and any clinical event have not been evaluated.

About Singletto

Active Protection
from Pathogens.

Singletto’s novel Oxafence® technology is being developed to meet the needs of healthcare, military, industry, and consumers – providing ongoing Active Protection™ from pathogens where it matters most.

Proven Science with Novel Applications

Singletto applies the proven principles of Photodynamic Therapy (PDT), long-used medically to treat cancer and skin disease, in novel ways to inactivate pathogens. Singletto’s Antimicrobial Photodynamic Inactivation (aPDI) technology can provide ongoing protection from dangerous pathogens, including SARS-CoV-2. Worldwide research, including the WHO-led DeMaND studies, continues to confirm the efficacy of aPDI technology.

Active Protection That Goes Further

Most current forms of pathogen protection only 1) trap or shield pathogens or 2) provide one-time disinfection. Very few protective technologies exist to actively destroy pathogens during and throughout product use or wear. Singletto’s Oxafence Active Protection technology can provide ongoing pathogen inactivation. Click below to read about our technology.

Antimicrobial Solutions

Oxafence inactivates pathogens through Antimicrobial Photodynamic Inactivation (aPDI). The protective dyesin Oxafence can absorb and transfer energy to the oxygen in the air creating singlet oxygen. Singlet oxygen has antimicrobial powers and the ability to inactivate viruses and bacteria. Click below to read about the science behind our technology.

Innovation Never Stops

Singletto’s Oxafence technology is based on simple and proven principles, but innovation drives us. Singletto’s leadership team, partner labs, expert chemists, virologists, and researchers push research and technology development forward every day. We’re optimizing the technology for specific use cases, environments, and unmet needs – and we’re partnering with trusted brands to develop products with this pathogen-fighting technology.
