Singletto
Singletto is a healthcare startup focused on developing and commercializing Oxafence™, an antimicrobial and antibiotic technology that provides ongoing active protection from pathogens. The company applies proven principles of Photodynamic Therapy (PDT) in novel ways to inactivate pathogens, including SARS-CoV-2, through its Antimicrobial Photodynamic Inactivation (aPDI) technology. Singletto's mission is to meet the needs of healthcare, military, industry, and consumers by offering innovative pathogen protection solutions that actively destroy pathogens during product use.

Products
Surgical mask with FDA-cleared antimicrobial photodynamic treatment
A surgical mask product incorporating a light-activated antimicrobial treatment that has obtained U.S. regulatory clearance for virus-inactivation claims.
Methylene Blue (MB) Pre-Treated Masks
Masks pre-treated with the protective dye Methylene Blue (MB) that provide immediate decontamination and ongoing antimicrobial efficacy against viruses including SARS-CoV-2, norovirus, Ebola, Lassa, and Nipah viruses.
ProGear Surgical Mask with Oxafence
FDA-cleared face mask applying Oxafence Active Protection™ technology to mask materials during manufacturing, inactivating 99.9% of tested viruses within 5 minutes on the outer surface, including H1N1 Influenza and OC43 human Coronavirus.
ProGear ASTM L3 Surgical Masks with Oxafence
The ProGear+Oxafence Surgical Masks provide the highest level of ASTM performance plus Oxafence Active Protection technology, which inactivates 99.9% of tested viruses after just five minutes. They feature a four-layer design providing Bacterial and Particulate Filtration Efficiency (BFE & PFE) and Fluid Barrier Protection meeting ASTM Level 3 standards (F2100-23).
Oxafence ProGear ASTM mask
FDA-cleared, virus-inactivating mask using Singletto's patented Oxafence Active Protection technology, designed to inactivate tested viruses.
N95 Respirators
N95 respirators are certified by the U.S. National Institute for Occupational Safety and Health (NIOSH) and are designed to filter at least 95% of specified airborne challenge particles under defined laboratory conditions. They form a tight seal against the wearer’s face and are used primarily for industrial worker safety.
