1. Adopt built-in plasma technology to decompose water into hydroxide ion and oxygen ion. The hydroxide ion binds the oxygen ion from pesticides, bacteria and virus, reducing to be water. It deactivates pesticides, bacteria and virus to achieve the goal of serialization and disinfection and also removal of any chemical residues; 2. The harmful bacteria and virus killing rate is >99%, and it can effectively remove >90% of dimethoate, DDVP and methamidophos; 3. It can extend the shelf life of fruits and vegetable for additional 3 days or more under the same conditions.
