Features: 1) Water tank: by a simple design with a handle bottle putting on. Convenient to use 2) LDC indication: LCD indication can confirm a state of a machine at first sight 3) Push button switch: while pushing the button lightly, the water flows 4) Reliable healthfulness: we adopt reverse osmotic membrane technology, it can remove underwater garbage and toxic substance and exchange it with pure water. A sealing up-type and tube prevent from second pollution of pure water 5) Water service supply-free: we do not have to connect it to water pipe. If you pour running water into a water tank and install it in the machine, it can swallow up pure water immediately. If there is a power supply, you can install it in any place, it does not take any space 6) Environmental protection and economy-type: a unique whole filtering system, producing 100% pure water, but common Ro system only produces 25% pure water, wasting serious 7) Perfect design: the design that unified reverse osmotic membrane technology and microcontroller all original filtering type system and an automatic washing function. Sealed tube and pipe prevent fresh water from contacting air. These designs offer reliable drinking water to you by security 8) Micro control: we completely automate it in a make water process. In addition, we possess automatic protection functions such as water leak perception 9) Automatic washing: when the pump working hour add up to 30 minutes. Pure-zing reverse washes RO membranes automatically for one minute, prolonging filters life efficiently
