(Japan Patent No. 3,468,568, US Patent No. 5,681,463) Pathogenic Bacteria (E. Colella, Echinec, Salmonella Bacteria, etc.), Mildew, Raw Animals (Cryptospordium, Giardia, Echinocox, etc.). and rainwater. You can change it into clean water that you can drink with confidence. Cannot be used with water that contains harmful substances. Super Delios hollow filament filter cleanly removes particles that are not dissolved in water, such as bacteria, mold and other fine particles that are hard to see in optical microscopes. However, substances that dissolve in water can pass beneficial minerals and harmful toxins. Some of the harmful organics are adsorbed and removed with fibrous activated carbon, but not completely unmatched. For this reason, water is not allowed to be used with harmful substances. For example, the water in rivers, marshes, and lakes that fish live, means that they are free of harmful substances or can only be blended in very small amounts. In contrary, if the water is not inhabitated, it may cause a large amount of acidic or harmful substances to blend in. Please do not use water that may be suspected. Do not filter milk, juice, coffee, etc. Do not use it as it will lose its taste or discolor. It may also cause clogging of the filter.
