Features: 1. Source sterilization with odor rejection, featuring a one-click ozone cycle for sterilization. It rapidly diffuses and penetrates cells for efficient utilization, causing strong oxidative damage to cell walls, leaving bacteria with no place to hide. 2. Long-term storage with daily freshness, as ozone inhibits the growth of ripening agents, extending the longevity of food freshness. 3. Accelerates the degradation of residual pesticides by up to 30-50 times faster than natural degradation. As a potent oxidant, ozone destroys the molecules of organic pesticides through strong oxidation, rendering them ineffective. 4. Compact and lightweight, designed for home use. It requires no filter replacement or liquid addition. Simply charge it and use it. 5. Eliminates various odors, including cigarette, pet, and clothing odors. Use for 20-40 minutes as needed.
