After an improvement is achieved by using GENKI, the condition will not worsen immediately after you stop using GENKI. The important point here is whether causes (such as equipment and raw water) of the deterioration of the condition are corrected. It is conceivable that poor conditions could return sooner or later if they were not corrected.
By using GENKI, it is possible to improve at a lower cost than to improve equipment problems. While using GENKI, you can solve the problems of the equipment little by little.
It is important to use them well in various situations.
