Gravity water purification machines use food-grade materials, uniquely produced sterile workshops in the country, 1. 5:1 wastewater is more water-efficient than water, hidden pipe design, double leak-proof water, user quality assurance, intelligent network, real-time monitoring of water quality by user mobile phones, complex filtration cores used by machines, ro membrane+ overfiltration to make drinking water healthier and safer. In the context of the popular entrepreneurship and innovation “internet+” initiative, gigi and cat technology have taken on the task of changing traditional business models, developing innovations, making full use of modern technology, and developing and producing a range of smart home-based health products on its own: household water purification machines, walkers, pipers, commercial water purification machines and air cleaners, based on the concept of “a glass of good water, good health and safety”, and developing a comprehensive management system for research and development, production and marketing. Treats every customer in good faith, based on a client-to-client philosophy. The life of the filter core is monitored at all times through machine chip implantation technology, remote transmission technology, smart cloud platform control technology, easier payment and easy monitoring of real-time data from water purification machines via cell phone microchips。
