Vitdam has developed a portable water bottle purifier equipped with antibacterial and purifying two filter systems. The built-in two filters make the tap water, stream water, and even muddy water to a drinkable clean water. And the environmentally friendly triple lamination (SLLDPE + BONx2) frees the water bottle from having the plastic odor. The UF filter removes water bacteria, bacteria ( general bacteria, Staphylococcus Aureus, Escherichia, Coli, Salmonella, Pseudomonas Aeruginosa), Fungi and other harmful substances. Also, the active carbon filter system removes chlorine, heavy metals. Light in weight and easy to carry because the water bottle is foldable. Not only great for travel and camping but everyday use as well.
