made in Japan Body size (width x depth x height) 2 x 5 x 2cm, body weight: 17g Copper fiber thinness: 30μm in diameter (1/3 the thickness of a human hair) Copper fiber length: 270m This portable water purifier, Cu-water, contains copper fibers made from a patented germicidal copper material (Patent No. 5246572) in order to quickly and fully utilize the antibacterial and residual chlorine removal properties of copper. A sterilizing effect test against Legionella, Salmonella, Staphylococcus aureus, and Escherichia coli O-157 was conducted by a third-party organization in Japan. As a result, it was confirmed that the number of infected communities decreased dramatically within one hour and reached zero within eight hours. [How to use for pets] Simply put it in a pet water dispenser or pet water bottle to remove residual chlorine from tap water and maintain water quality due to the antibacterial action of copper. [How to use with a 500ml plastic bottle] Not only can it be used for pets, but it can also be used for drinking by placing it in a container containing tap water, such as a 500ml plastic bottle. Even if you make it 2-3 times a day, one can last for about 6 months. [How to start using] When using it for the first time, soak it in hot water of about 80℃, and once the product is submerged, it can be used. Approximately half of the chlorine in tap water poured into a pet water dispenser will be removed in 6 hours in a place exposed to sunlight, and in 24 hours indoors. If the disinfectant effect is lost, bacteria will easily breed, which will affect the health of your pet. Just by putting copper fiber Cu-water into a container, it suppresses the growth of bacteria and maintains clean water quality. The portable water purifier Cu-water removes 99.9% of residual chlorine just by putting it in a plastic bottle with tap water. Copper has excellent antibacterial properties (trace metal action), and by making it into patented copper fibers, it quickly suppresses the growth of bacteria and maintains water quality. Verification results show that it is effective enough to drastically reduce Legionella, Salmonella, pathogenic Escherichia coli O-157, Staphylococcus aureus, and the carcinogen trihalomethane in one hour, eliminating bacteria to almost 0% in eight hours, and is not harmful to the body. You can easily make delicious water. By putting it in pet water dispensers, water bottles, etc., it suppresses the growth of bacteria and maintains water quality, which helps maintain the health of your pet.
