Promoting copper for the benefit of Global Health

Coppermedics™ introduces The Virus Buster Face Mask
Kills Coronavirus (COVID-19) in Minutes

Virus Buster Mask is the first protective mask surface material to be successfully tested against the actual SARS-CoV-2 virus, proven to deactivate more than 99.57% of that virus within 10 minutes, and 99.999% of the virus causing the COVID-19 illness in less than 30 minutes.

Copper has long been known to have antimicrobial and antiviral properties but – until this testing – there have been no known successful mask surface material tests against the SARS-CoV-2 virus causing the COVID-19 illness in this type of challenge.

The COVID-19 pandemic has killed over a million people worldwide. The Coronavirus is easily spread through aerosols. The wearing of face masks has proven to reduce infection. However, the Coronavirus can easily land on the surface of a mask and a wearer can inadvertently touch the material and become infected.

Virus Buster face mask works to greatly minimize this possibility while also reducing the chance that an infected person can spread the virus by breathing through a mask.

The Mask

Virus Buster face masks are light, breathable, washable, and reusable.

The copper ions cannot be washed off and are chemically bonded to the polymeric fabric.

The Virus Buster face mask is comprised of 4 layers of material:

  • An outer antiviral layer which includes the tested and proven copper ion-bonded fiber
  • A virus protection layer that contains a nanomembrane filter
  • A support layer
  • An innermost skin care layer

The Folder Mask is available now, shown in the photos above, and in the first section above, labeled. A medical style mask will be available in the near future.

how copper kills the virus



Virus Buster uses the antiviral properties of copper, known for many years in the medical industry. A Korean company named Medifiber developed and patented a non-woven fabric composed of polymer fibers coated with millions of copper ions (Cu+). The fiber is called CAZ and makes up the antiviral surface layer of the mask.

The high concentration of the copper ions at the mask’s surface is now proven to destroy the virus.

The Virus Buster mask was widely used in Korea during the early stages of the COVID-19 pandemic. For the first time, Virus Buster masks are available in the United States, and with widespread use here, could help control the spread of COVID-19.


The first face mask proven to kill the SARS-CoV-2 virus on the surface within ten minutes. Virus Buster Mask is comfortable and FDA approved for personal use, washable and reusable for about 300 hours of wear.
