No residual water liner design The filter jug liner is an important component to isolate tap water and filtered water. If the filtered water remains at the bottom of the inner tank, it is easy to breed bacteria, making the outlet of the filtered water a breeding ground for bacteria. Choose the open liner design, the water flow is clean and refreshing, and there is no residual water.

Be wary of ASA materials!
According to the data, ASA material contains acrylonitrile. Acrylonitrile monomer is a carcinogenic and mutagenic substance. Once the precipitation exceeds the standard and migrates into food, the human body will experience dizziness, fatigue, nausea and vomiting, numbness of hands and feet and other symptoms after absorption. Some imported clean water bottles are made of ASA material, so you need to pay attention when purchasing.
