The silver ion antibacterial and odor-removing function in the Mijia Refrigerator Side-by-Side 635L is achieved through a specially designed formula embedded in the built-in filter. This formula contains metallic silver ions, which are well known for their antibacterial properties. The silver ions can effectively adsorb and break down harmful substances such as trimethylamine and methanethiol, which are common causes of unpleasant odors in refrigerators. By neutralizing these compounds, the technology helps maintain a fresh and clean internal environment. Additionally, this method allows the filter to retain its antibacterial effectiveness over an extended period, meaning that the filter does not require frequent replacement. As a result, the refrigerator ensures long-term odor control and contributes to safer, healthier food storage.
