Interesting- i think the other article i read about the Israeli masks earlier stated that they created some kind of a charge in the mask too that traps the virus while antimicrobial annihilates the virus
Yup- found some info on another technology similar to the sonovia masks:
Argaman Technologies, an Israeli textile research company, claims its BioBlocX masks contain cotton and polyester fibers embedded with accelerated copper oxide particles. Similarly to Sonovia’s tech, Argaman says that when virus particles hit the mask, positive ions from the copper attach themselves to the virus and destroy its ability to replicate. The masks also include a layer of a nanofiber membrane that allegedly filters out pathogens.

The electroceutical dressing is currently FDA cleared and commercialized by Vomaris Inc. It is made of polyester fabric printed with alternating circular metal dots of elemental silver and zinc metals that create moisture-activated microcell batteries
