Our trademark product is the EHW apparatus, 'Trim Ion', for household use. With this machine, your home tap water is purified before undergoing a process of electrolysis to create a hydrogen-rich alkaline water. The EHW apparatus is a controlled medical device regulated by laws governing medical products and equipment. In Japan, it has been recognized for its efficacy in improving and treating gastrointestinal conditions and is manufactured in a factory certified under the ISO 9001 and ISO 13485 standards for quality management. Thanks to our original "Double Auto-change Cross-line Method" technology, there is no need to clean, replace or otherwise maintain the apparatus's electrolyzers. By switching the polarity of the electrodes and waterways at regular intervals, this method prevents minerals from accumulating on the electrodes to achieve stable, long-term electrolysis.

According to a 2019 survey on the current state and outlook of the water purifier and EHW apparatus market.

At the time of our founding when water and safety were taken for granted, we began focusing on the functional potential of water and engaging in joint research with academia to explore the mechanism and functions of our water. The results of this research were later released in international academic journals and other publications.
Based on evidence and technologies accumulated throughout our history, the Trim Group has developed a lineup of transformative products and provides our integrated full-scale services from manufacturing and sales to after-sales support. Thanks to this record of achievements and the wide recognition we have received, our Electrolyzed Hydrogen Water (EHW) apparatuses are now used in over one million households. We promise to continue promoting EHW until there is one Trim Ion in every home.
