Many people consider brass doorknobs to be a matter of style. Whether it’s the antique look of a Victorian house or the sleek gold touch in a modern home, brass has been a popular choice in interior design. However, there is an important reason why this metal has remained preferred over time. It’s not only about how it looks; there is a scientific aspect that contributes to health protection every day.
One key reason doorknobs are often made from brass, which is a mix of copper and zinc, is due to a biological concept known as the Oligodynamic Effect. Brass is naturally antimicrobial, unlike materials like stainless steel, plastic, or aluminum. The metal ions present in brass can enter the cell walls of germs, including bacteria, fungi, and some viruses, effectively neutralizing them upon contact. It is interesting to note that while viruses can survive for several days on stainless steel handles, a quality brass or copper doorknob can self-disinfect in about two hours.
Consider all the hands that touch doorknobs in busy places like public buildings, hospitals, or even at home. Door handles are common ways that germs spread, including those that cause illnesses like colds or the flu. By choosing brass, architects and homeowners are using a form of passive healthcare technology that operates continuously without the need for chemical cleaners or electricity. This makes it a very sustainable option for maintaining a germ-free environment in homes.
