Sonovia mentioned in the Jerusalem Post following another round of exciting test results of its antiviral fabric

The Jerusalem Post published an article about Sonovia on July 7th, 2021, titled “Israeli mask co. says can protect wearers against Delta variant” and written by Maayan Jaffe-Hoffman.

The article focused on the latest test report from the VISMEDERI laboratory which showed once again that the zinc-embedded fabric used in Sonovia’s SonoMask™ and SonoMask™ Pro face masks has “potent antiviral activity” against variants of the SARS-CoV-2 virus.


According to Professor Amos Adler, Scientific advisor to Sonovia LTD as well as a consultant for the European Center for Disease Control (ECDC) and the director of the Clinical Microbiology Laboratory at the Tel-Aviv Sourasky Medical Center (TASMC):

“The antiviral activity of various Sonovia treated fabrics (CuO and ZnO) was tested by the Vismederi laboratory according to the ISO 18184:2019 standard (Textiles – Determination of antiviral activity of textile products). The activity was tested against two reference strains of the COVID-19 virus, the COV2019 ITALY/INMI1 strain and a strain that belongs to the WHO Alpha variant group. In both strains, the tests showed potent anti-viral activity of the treated fabrics. The antiviral effects of metal-coated fabrics is not fully understood, but it is thought to be caused by the release of free radicals ( ). COVID-19 variants might have different epidemiological or immunological properties that are the result of point mutations in critical areas of the receptor binding domain ( Still, their overall structure and biophysical properties of the virus (including its susceptibility to these radicals) are almost identical. Hence, the antiviral effect exerted by the Sonovia treated fabrics is expected to be present in all COVID-19 variants, including the recent Delta variant.”

As the coronavirus continues to infect millions of people worldwide and impact lives everywhere, becoming more sophisticated and dangerous from one mutation to the next, masks must become more sophisticated as well in how they defend against COVID-19. Passive filtration offered by standard masks is no longer sufficient. While passive filtration does capture some of the virus load, it does not provide 100% protection, nor does it prevent hand contamination from handling contaminated masks. Contaminated hands through coming into contact with the face may then transfer the virus back to the body through the mouth, nose or eyes, thereby leading to the inevitable infection which was meant to be prevented.


With the progression, endurance and sophistication of the coronavirus, sophisticated weapons of mass protection are required in the form of masks offering active protection . The SonoMask™ Pro mask which uses 2 layers of antiviral fabric as well as a middle filter layer, covers all bases, offering both passive filtration at the highest level of 97% efficacy of 3-micron particles , as well as active protection through its antiviral, antibacterial and antifungal fabric, neutralizing viruses, bacteria and fungi with over 99% efficacy .

As stated by David Brookstein, SC.D, in his paper: Public Health Protection Against Bioterrorism via Respiratory Pathogenic Viral and Bacterial Agents using Protective Face Masks:


“Protective face masks, at the minimum, should provide adequate cover of

the wearer’s mouth and nose. Further, they should provide a tight fit while still remaining comfortable. Their function is to minimize or even prevent pathogenic-containing mucosalivary secretions from passing through the mask during exhalation and also minimize or even prevent pathogenic respiratory aerosols or droplets exhaled by others from being inhaled.


This is referred to as “capturing ability”. However, capturing ability, while

necessary, is not sufficient to prevent infection from a pathogenic agent. To be optimally effective in mitigating spread of respiratory borne diseases, the mask should also deactivate or kill the pathogenic agents. The ideal mask would be able to both capture and deactivate or kill either of these types of pathogenic agents. Further, the protective mask should be reusable for a period of time and be able to be occasionally cleaned using conventional laundering equipment.”


Sonovia has funneled over 10 years of research and development of antiviral, antibacterial and antifungal fabrics into its award-winning face masks. The SonoMask™ Pro – a sophisticated active protection mask for a sophisticated virus. Stop hoping you are protected – start ensuring you are protected with the SonoMask™ Pro.
