it is a private power generation type, it is possible to set it up even in the water circumference without the electrical hookup. Troublesome wiring is not needed. The ozone water comes out only for the installation easily. The switch with raw water is also one-touch. (It is possible to install it in a general faucet. ) The power plug had to tie to the generation of the ozone water because electricity was necessary so far. Then, this problem was solved by designing the power generation method by the water current, and using the technology of our original small dynamo, and the first unnecessary power supply small ozone water generation machine in the world was developed. · There are sterilization, a deodorization, and a bleaching action. · A harmful nitrogenous substance is resolved. · The proliferation of mold and the bacillus is pressed. · Effect of fly cockroach etc. of evasion Because the medicine is not used, these effects can be done safely low-cost.
