Other touch surfaces say they are antimicrobial – only we can prove it
Stainless steel may look clean, but deadly bacteria that threaten patient safety can thrive on this material for weeks or even months.
Antimicrobial Copper is the first metallic touch
surface registered by the EPA to continuously
kill greater than 99.9% of bacteria* that cause hospital acquired
infections and degrade hygiene in hospitals.
Extensive EPA laboratory testing is
required to make public health claims.
Antimicrobial Copper has passed all EPA testing protocols, is
registered by the EPA to make public health claims, and is another
weapon for Infection Control and Prevention professionals in
Antimicrobial Copper's efficacy against the 6 registered
bacteria is summarized below.
Methicillin-resistant Staphylococcus aureus
Antimicrobial Copper provides supplemental defense against MRSA.
Copper is an excellent material for frequently touched surfaces
because of its ability to kill MRSA in between regular
Infections caused by Staphylococcus aureus are commonly
found in healthcare settings, but are also present in fitness
facilities, schools and assisted living facilities.
Antimicrobial Copper kills 99.9% of this bacterium within two hours
in between routine cleanings and touches. The chart below
shows the effectiveness of an Antimicrobial Copper surface.

Antimicrobial Copper kills 99.9% of E. coli O157:H7
within two hours adding an additional level of protection to good
hygienic practices. The chart below demonstrates that Antimicrobial
Copper kills E. coli O157:H7 while stainless steel,
plastic have virtually no effect after six hours.

The graph below shows Antimicrobial Copper's intrinsic ability
to kill this resilient bacterium. Within two hours, more than 99.9%
of Enterobacter aerogenes colony forming units is killed
on copper and brass, two Antimicrobial Copper alloys, while very
little reduction is observed on the stainless steel.

aerogenes on Touch Surface Materials - Click on graph
Antimicrobial Copper surfaces effectively kill this pathogen
while other surface materials are relatively inert. U.S. EPA tests
confirmed that Antimicrobial Copper alloys kill more than 99.9% of
Pseudomonas aeruginosa within two hours under 3 test
Vancomycin-Resistant Enterococcus faecalis
VRE is resistant to several antibiotics and is easily spread by
touch throughout the healthcare environment. Antimicrobial
Copper surfaces kill greater than 99.9% of VRE within two hours of
exposure providing added protection against this resilient
*Laboratory testing shows that, when cleaned regularly,
antimicrobial copper surfaces kill greater than 99.9% of the
following bacteria within 2 hours of exposure: MRSA, VRE,
Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas
aeruginosa, and E. coli O157:H7. Antimicrobial copper surfaces
are a supplement to and not a substitute for standard infection
control practices and have been shown to reduce microbial
contamination, but do not necessarily prevent cross contamination
or infections; users must continue to follow all current infection
