Silvertek’s FDA-listed antimicrobial masks send viruses off

29 October 2020

Polygiene partner Silvertek® has taken its mask design a step further with FDA-listing for their NanoFit Masks with Polygiene ViralOff antimicrobial technology. 

Polygiene is partnering US brand Silvertek to provide award-winning antimicrobial textile treatment ViralOff – proven to reduce 99% of germs within two hours – for its face masks. This is a tested and certified technology per the global standard of ISO18184:2019 against SARS-CoV-2, H3N2 and H1N1, says Polygiene.

Unlike most masks on the market, which are being manufacturing under Emergency Use Authorizations, SilverTek had begune the process prior to Covid-19 and therefore had the benefit of time and experience to craft its proprietary FDA-listed mask. For example, SilverTek discovered early in their mask development that exhalation valves were an unsafe component due to their release of the wearer’s unfiltered exhale. For this reason, airlines, many public school districts, and entire regions such as the California Bay Area are now banning masks with valves.

”We wanted to find the best antimicrobial treatment for our NanoFit mask and evaluated numerous companies in the process”, said Silvertek president Ji-mei Ma. “We were looking for a partner we could trust - who was environmentally friendly, wellness-conscious, and an established player in the field of antimicrobial technologies. We are glad to have selected Polygiene and to have ViralOff® technology to protect our NanoFit Masks.”

”We are excited that ViralOff adds value to a FDA-listed textile mask. In addition to the high antimicrobial performance, these masks will also need less washing* and will therefore last longer, which is good for the user and the environment”, says Ulrika Björk CEO Polygiene.

ViralOff protects treated fabrics from bacterial and viral contamination but does not protect against infection or disease.
