Copper Efficacy

Although US EPA public health claims are valid only for Methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus aureus, Enterobacter aerogenes, E. coli O157: H7 and Pseudomonas aeruginosa., laboratory research has also demonstrated that copper is effective in eliminating fungi, bacteria and viruses that frequently contaminate air handling systems.

The following content is based upon independent scientific research and is provided for informational purposes only. The conclusions reached are the opinions of the researchers and authors. U.S. EPA-approved testing demonstrates antimicrobial effectiveness for copper alloys against only the following organisms: Staphylococcus aureus, Enterobacter aerogenes, Escherichia coli O157:H7, Pseudomonas aeruginosa and Methicillin-resistant Staphylococcus aureus (MRSA). Any reference to effectiveness against other organisms has not been proven by U.S. EPA-approved testing. No claim of antimicrobial effectiveness is made, either express or implied, with regard to organisms other than those identified above.
