It has been stated that 80% of infections from bacteria are spread by touch. It is not practical to clean each of these surfaces every time they are contaminated. There are strong indications that bacteria found on frequently touched environmental surfaces such as door handles can play a role in infection transmission.
According to an article published by U.S. Environment Protection Agency (EPA) on (10th February 2021), copper alloys provide long term effectiveness against viruses including Covid-19, based on testing against harder-to-kill viruses. This testing was supported by the Copper Development Association demonstrated certain high percentage copper alloy products can uninterruptedly kill viruses.
Anti-microbial copper alloys can be fabricated into a variety of surfaces, including door handles and doorknobs in real life. "Copper is the fastest thing that can kill anything," said Michael Schmidt, a professor of microbiology and immunology at the Medical University of South Carolina and a leading researcher on antimicrobial copper.
Copper/ Brass & Bronze
Copper, brass, and bronze are part of a category of metals known as “red metals”, which are characterized by their reddish tint. While copper is a pure metal, brass and bronze are copper alloys (brass is a combination of copper and zinc; bronze is a combination of copper and tin) Copper has lifelong anti-microbial property.
The first clinical study using copper as an anti-bacterial material was carried out at Selly Oak hospital in Birmingham in 2007. The results showed that, compared to control surfaces, the copper items had 90-100% less microbial contamination. Copper and its alloys with kill pathogen microbes and break down their genetic material. It is continuously active, easy to clean, is compatible with standard hospital cleaning and highly durable. The registrations are based on studies supervised by EPA which found that copper alloys kill more than 99.9% of disease-causing bacteria within just two hours when cleaned regularly.
Commy lever handles are mainly made of copper. Nearly 100 door handles have unique shapes and textures to create a stylish feel for your room. In addition, the copper door handles are antibacterial. Bacteria and viruses don't stay on your hands.
Copper Door Handles Are Widely Used In Life
In recent years, human beings have continued to fight back against Covid-19, and they have also begun to pay attention to various antibacterial and antiviral products. Since international authoritative departments or
experts have shown that copper is effective in killing bacteria and viruses, copper has been widely used in many workplaces, residences and hospitals.
The new coronavirus outbreak is continuing to grow. The public understands that "Touch" is one of the infection routes. The virus can easily enter the body by touching the eyes, nose and mouth without disinfection after touching various surfaces. In fact, our hands often touch the door handle every day, and the surface of the door handle is covered with bacteria and viruses, and most door handles are made of stainless steel or plastic, they have no antibacterial and antiviral, which increases the risk of virus transmission.
An earlier study, published in The New England Journal of Medicine, found that the new coronavirus can persist on plastic and stainless-steel surfaces for up to three days, but only on copper surfaces for four hours.
