Israeli start-up Sonovia expects its improved anti-microbial fabric to be capable of neutralizing 99 percent of the coronavirus to which it is exposed.

The company announced last month that the Microspectrum (Weipu Jishu) lab in Shanghai had confirmed that Sonovia’s fabric neutralized more than 90 percent of the coronavirus in its tests.

Since this test material was submitted several months ago, Sonovia’s proprietary zinc-coating formulations have been optimized even further, and the company expects its new fabric to be found 99 percent effective against coronavirus in upcoming EU-authorized laboratory tests.

The new fabric is already being used in the company’s SonoMask, which is commercially available on Sonovia’s website.

The SonoMask is reusable and has been tested to be effective even after being washed 90 times.

In addition to neutralizing coronavirus on contact, the double-layered mask also filters 98 percent of particles of up to five microns.

This SonoMask has been approved by the FDA for non-medical use and is in the process of FDA testing as a new category of protective equipment for healthcare workers.

The company’s technology is based on a lab-scale sono-chemical process that was developed at Bar-Ilan University.

“The technology is based upon a physical phenomenon called cavitation,” Dr. Jason Migdal, a research scientist with Sonovia, told The Jerusalem Post.

“Sound waves are used to physically infuse desired chemicals onto the structure area of materials, enhancing them with clinically proven antiviral and antibacterial properties,” he said.

The Tel Aviv-based company started manufacturing its product in March at a plant near Nahariya.

“When coronavirus started, we were an Israeli start-up,” said Dr. Migdal. “Now, we are a commercial business that is having success internationally.”
