1. Effective in removing odors. Ozone is essentially oxygen. When pollutants come into contact with ozone, an oxidation reaction occurs, breaking both apart, and ozone (O3) is converted into oxygen (O₂) for human breathing. 2. Long-lasting and effective. Ozone helps eliminate odors and converts them into neutral odors. When pollutants come into contact with ozone, ozone (O3) is converted into oxygen (O₂) for human breathing. 3. Easy to clean. 1. Ozone output: The ozone generator can output 60,000 mg of ozone per hour, making it an efficient O₂ air purifier for removing odors. It is durable, has a long service life, and is easy to clean. 4. Sturdy and durable. Easy to use: Just turn the timer knob and leave the room. Make sure no one (or pets) are in the room while the ozone machine is running. The timer function can be set from 0-120 minutes, or you can use the "HOLD" mode to keep it on. 5. Long-lasting and durable Warning: All ozone generators should only be used in unoccupied spaces. After treatment, please wait 15 to 45 minutes before entering the space, or open external doors and windows when re-entering.
