Copper has a long history in design, but one of its most impressive qualities that often gets overlooked is copper as an antimicrobial. In spaces like kitchens and bathrooms, where surfaces are constantly touched and exposed to moisture, this property becomes a practical advantage.
In this guide, you’ll learn why copper is considered antimicrobial, what it protects against, and the main benefits it can bring to your home. From reducing harmful bacteria to lowering the need for harsh cleaners, copper offers both health and design advantages that last for years.
Is Copper Antimicrobial?
Yes, copper is antimicrobial, meaning it can kill or inhibit the growth of microorganisms, including bacteria, viruses, and fungi. Copper surfaces are highly effective in reducing microbial contamination, thanks to a process known as contact killing. When microbes come into contact with copper, the metal releases copper ions, which disrupt the cell membranes of microorganisms.
What Does Copper Protect Against?
Copper is capable of protecting against a wide variety of microorganisms, making it a powerful tool for maintaining hygiene, especially in places like hospitals where infection control is crucial. Let's break down what copper protects against.
Kills Harmful Bacteria
Copper rapidly kills a wide variety of harmful bacteria that thrive in kitchens and bathrooms:
-
MRSA
-
E.Coli
-
Salmonella
-
Streptococcus pneumoniae
These bacteria are some of the most common culprits behind foodborne illness and infections, making copper a powerful ally in keeping homes and businesses safer.
Prevents the Spread of Viruses
Copper has been proven to inactivate viruses, including the flu virus (H1N1) and coronavirus, both of which can linger on surfaces in kitchens and bathrooms. With copper, you don’t have to rely solely on cleaning solutions, as its inherent properties actively work to neutralize viruses on contact.
Reduces the Growth of Fungi
Copper’s antimicrobial action extends to fungi as well, such as Candida albicans (a common cause of fungal infections) and Aspergillus spp. (which can cause respiratory issues). In damp environments like bathrooms, a copper bathtub or sink can help prevent mold and mildew growth, contributing to a cleaner, healthier space.
Other Microorganisms
Copper is also effective against other types of microorganisms, such as:
-
Acinetobacter baumannii
-
Enterococcus
By targeting these additional pathogens, copper extends its protection beyond everyday germs to support a cleaner and healthier environment overall.
What Are the Benefits of Using Copper as an Antimicrobial in Your Home?
Beyond its ability to keep surfaces cleaner, using copper as an antimicrobial can offer several benefits.
Self-Sanitizing
In damp environments like kitchens and bathrooms, bacteria and fungi multiply faster because water provides the conditions they need to grow and spread. Surfaces that stay wet or are touched with wet hands (like sink handles, faucets, or shower fixtures) typically become hotspots for contamination.
Copper sinks, bathroom faucets, and showerheads help prevent the buildup of mold, mildew, and bacteria that thrive in moisture-rich areas. This makes copper a reliable material for maintaining cleanliness in spaces that are prone to humidity.
Reduces Odors Caused by Bacteria
Bacteria often cause unpleasant odors throughout the home. Copper’s antimicrobial action helps reduce the bacterial growth that leads to these odors, keeping your home smelling fresher for longer. In kitchens, this is especially helpful in areas that handle food waste or spills, where bacteria can quickly multiply.
Reduces the Need for Harsh Chemical Cleaners
The health benefits of copper even extend to creating a safer atmosphere for children, pets, and anyone sensitive to strong cleaning agents. Since copper is always actively working to kill germs, you don’t have to use harsh chemical cleaners and disinfectants.
Long-Term Durability
Copper is incredibly durable and resistant to wear, making it a long-lasting investment in your kitchen or bathroom. Even with frequent use and cleaning, copper maintains its antimicrobial properties, unlike some coatings or chemical treatments that lose their effectiveness over time.
Easy To Maintain
While copper surfaces work continuously to fight germs, they do require some care to maintain their appearance. Regular cleaning with a soft cloth and mild soap ensures the surfaces remain both functional and attractive for years.
Unlike stainless steel or plastic, which can scratch or become worn over time, copper develops a unique patina that protects the metal and doesn’t affect its antimicrobial properties.
Prevents Cross-Contamination
In kitchens, where food preparation and cleaning happen frequently, copper can reduce the risk of cross-contamination. Copper tables and surfaces help eliminate germs that might otherwise transfer from one surface to another, especially when handling raw meats or washing produce.
Even if you think you’re really careful, you might mindlessly touch a copper range hood or lift a trash can lid without realizing you’re potentially spreading germs. When these surfaces are made of copper, they give you an extra layer of protection against the transfer of harmful microorganisms.
How Long Do Copper Fixtures Remain Antimicrobial?
The antimicrobial properties of copper fixtures are inherent to the metal itself, so they don’t wear out over time. Even with regular use, cleaning, or tarnishing (which forms naturally), copper continues to kill bacteria and viruses effectively. As long as the surface isn’t coated with something like paint or wax, copper will keep working to reduce germs throughout its lifespan.
