We have sold many top brands water ionizers(Kangen Enagic, Toyo, AlkaBlue, Nexus, KYK, Tyrent, Life Ionizer EmcoTEch, BionTech) and think all the top water ionizer models(no matter the brand) make good alteration to water. The similarity ends there. The differences are in water filtration power, technology , sophistication & design(i.e.:SMART electrodes & DARC II electrode cleaning systems,AutoAdjust optimal performance with low power ), manufacturing quality and durability. Our unique focus is on the importance of clean water. AlkaViva’s UltraWater filter performance (and testing ) is unique . We are the only company who represents two top manufacturers offering water ionizer models that fill different niches. We offer you the best of the best – in water filtration, water ionizer performance, electrodes , electrode cleaning system & durability and customer experience. That is choice. That is smart.
