HOW IT WORKS
Copper is a natural element with antimicrobial properties, meaning it has the ability to eliminate microbes, like fungi, bacteria, and viruses.
What is copper’s antimicrobial efficacy?
After rigorous testing, the Environmental Protection Agency (EPA) labeled copper alloys as public health material. It effectively and continuously kills 99.9% of bacteria on surfaces within two hours of contact.
Antimicrobial copper has undergone extensive laboratory testing and passed all protocols, which is required by the EPA to make public health claims.
DID YOU KNOW?
The use of copper as a disinfectant dates as far back as ancient Egypt. It is one of the most effective natural materials in the fight against bacteria and viruses.
How does contact killing work?
When a frequently touched surface is contaminated with bacteria, copper ions break through the cell wall of viruses, germs, bacteria, and fungi, destroying their genome.
Copper uses ionization to attach ions onto the bacteria, thereby disrupting the cell walls and destroying the RNA and DNA. This results in structural dysfunction and prevents the cells from mutating, i.e. they are not able to grow resistant to copper.
The copper particles dissolve from the surface and damage the microbic cell.
Cell-membrane ruptures due to copper-related distress.
Copper ions cause the formation of ROS (reactive oxygen species) and thereby lead to intracellular damage.
Nucleic acids (DNA and RNA) are degraded, making it impossible to survive.

WHY COPPER AND NOT SILVER?
Copper and silver kill a variety of different bacteria. However, copper is a safer and more effective choice.
COPPER IS ALSO EFFECTIVE AGAINST VIRUSES
Copper is effective at eliminating a broad spectrum of pathogens including viruses, bacteria and fungi.
Copper is proven to be effective at eliminating the COVID-19 virus within 3 hours.
Silver is mainly antibacterial and less effective against viruses and fungi.
COPPER WORKS AT ALL TEMPERATURES
Copper is effective at killing both gram-positive and gram-negative bacteria across all levels of temperature, making it a suitable solution for any environment.
Silver's efficiency is affected by ambient temperatures. It is found to be less effective in environments with neutral temperatures.
A study by The Society for Applied Microbiology demonstrated that antimicrobial activity was detected in silver at 35°C (95°F). This is relatively high. At room temperature biocidal activity was negligible.
COPPER HAS A LONGER LIFETIME/ DURABILITY
Owed to a low solubility, copper has a high lifetime and durability.
According to the Environmental Protection Agency, silver has a lower durability than copper.
COPPER HAS A LOWER TOXICITY LEVEL
Copper is the only metal that has antimicrobial properties and is also an essential micronutrient for humans and other living things.
Copper is used in neurotransmitter synthesis, cell respiration and other vital processes.
The toxicity of silver is 65x higher than copper according to the EPA.
COPPER WORKS AT ALL HUMIDITY LEVELS
Copper is efficient at eliminating pathogens across all levels of humidity, making it a suitable solution for any environment.
Silver is found to be affected by ambient humidity. In presence of sweat for example, a decreased efficiency is found.
A study by The Society for Applied Microbiology demonstrated that antimicrobial activity was detected in silver at 95% relative humidity. This is relatively high. At 20% humidity biocidal activity was negligible.
COPPER IS GOOD FOR THE HUMAN BODY
Copper promotes wound healing as well as the elasticity of our human skin.
Copper is also an essential micronutrient used in important biological processes.
Silver can cause mild skin irritations and abnormalities in basic cell functions.
