Here you can find information about the technology of the Copperline copper mask

Copper actually kills the virus, that is the important thing, a normal face mask does not. A normal mask can protect, it can prevent, but it cannot kill the virus. Actually, the copper mask kills the virus.

Copperline - How copper works

Copper kills viruses and bacteria - bacteria that hit it are killed within five seconds, more than 90 percent of the CoVid-19 virus is destroyed within five minutes and the remaining part within thirty minutes. The mask is self-disinfecting and viruses that can normally survive on masks for up to seven days are gone in half an hour.

How does it work? The copper is positively charged, the virus negatively charged. If the virus and copper meet, the positively charged copper thread attracts the negatively charged virus and it sticks to it. The envelope of viruses, or the outer cell membrane in the event of encountering bacteria, is destroyed by direct contact with the copper ions. The cell loses water and nutrients. Copper ions penetrate the cell, enzymes are destroyed and the virus / bacterium dies. With enveloped viruses, such as the current corona virus, the genetic material of the virus is destroyed and is then harmless.

With the COPPERMASK, Copperline® has developed the world's first antiviral and antibacterial functional mask of its kind.

Copperline - patented and antiviral

Copperline uses these special properties of copper in its patented copper-ion yarn. Processed in textiles, these are washable and have a long service life. Because: the high-quality ionized copper threads guarantee the effect even after many washes and ensure that the fabric produced in this way offers a maximum attack surface for fighting viruses and bacteria.


The following examples explain the relationship between the mode of action:


  • We use ionized copper yarn, an expensive raw material. The copper ions are distributed throughout the entire yarn material. This is technically more complex to manufacture than, for example, with 'encapsulated copper', a simpler and cheaper method in which a thin copper layer is only vapor-deposited on the outside of a normal yarn thread. Another method we heard about is "shooting" tiny copper nano-spheres into a tissue. With these methods, the copper washes off after a few washes. It is not yet known whether the smallest amounts of copper are inhaled (because the globules dissolve). Extensive test series have been carried out with our ionized copper yarn with the result that firstly, the effectiveness is still 100% even after many washes, and secondly, no particles are released. In the interests of your own health, Copperline guarantees that the right technology has been applied to the use of copper for the manufacture of masks.  
  • The patented three-dimensional fabric ensures that the woven copper thread has the greatest possible surface effect. We would like to explain this briefly figuratively: Imagine a spiral, perhaps like the one in a ring binder. As in such a spiral, our copper thread is interwoven with three layers of masking material. As a result, a virus that hits the mask material either directly through droplets or through aerosols is first spatially deflected by one of the three layers and then "caught" and destroyed at one point by the spiral copper threads. The three layers of the mask also increase the filter effect.    


In the independent medical study, in which the Copperline material was tested alongside other copper textiles with regard to the effectiveness of the destruction of the CoVid-19 virus, our material performed particularly well. This is all the more remarkable as the other materials contain 49% copper and 60% copper, i.e. a significantly higher copper concentration than our 22% copper content. The scientists were able to prove that the three-dimensionally woven copper thread makes the surface particularly large and therefore the patented mask material has the comparatively highest effect.


“The DNA of the SARS-CoV-2 virus consists of a double helix, and this is held together with connections made of hydrogen. When these connections are broken, the DNA of the virus and bacteria is destroyed. Since copper is a charged metal, it breaks this hydrogen bond, so that the DNA of the virus and bacteria is destroyed. If the DNA is destroyed, the cell cannot survive. Copper has the best affinity for binding to the DNA molecules. "

Some history ... the effects of copper have been known for thousands of years

  • Copper was used for the medical treatment of various ailments over 5,000 years ago. Early writings of Ayurvedic medicine report a method for water purification, in which water draws in a copper kettle overnight.
  • The ancient Egyptians cleaned wounds with copper 3,500 years ago; impressive healing properties have been handed down.
  • 2,000 years ago, in ancient Rome, knowledge of the purifying power of copper was used to ensure a sterile water supply. The kettles of the Roman legions were made of copper because there the water did not rot there much longer than in other containers.
  • During the cholera epidemics in the middle of the 19th century, miners of copper mines were hardly affected by cholera diseases. However, there was still no explanation for this.
  • With the discovery of the bacteriologist in the first half of the 20th century, the causal relationships were deciphered in their fundamental nature for the first time.
  • In many countries, e.g. B. in England and Greece, copper fittings and doors, inter alia. Introduced experimentally in hospitals. The result showed a massive reduction in so-called hospital germs.
  • During the respiratory diseases MERS and SARS, researchers found that exposure of such corona viruses to copper contributes to a reduced risk of infection and permanently deactivates the viruses.
