How Copper Kills Viruses

Copper metal - Anitmicrobial- Kills Viruses

“We’ve seen viruses just blow apart...”
- Bill Keevil, professor of environmental healthcare at the University of Southampton.


Copper is like kryptonite to many of the strongest and most infectious germs including coronavirus. Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this phenomenon.

Infectious organisms like E. Coli, MRSA, and Influenza have all been shown to be inactivated by contact with copper surfaces... Some within just minutes of exposure! 

That's pretty impressive.

It's also the reason we would never use any other material to create the Copper Key. We've crafted this clean key with Copper for maximum antimicrobial power, without sacrificing durability. 

While we still advise everyone to follow hand washing and overall hygiene guidelines. We do believe the Copper Key is a powerful tool in limiting your exposure to the harmful germs that go unseen to all of us. 

As a plus, you can save yourself and our planet a few dozen pairs of one-time use gloves. 😉  



Copper kills coronavirus. Why aren’t our surfaces covered in it?
