Precautions for use:
1. Because of the particularity of negative oxygen ion parameters, it is not suitable for long-term application in high humidity environment with air humidity over 90%
2. Keep away from electromagnetic interference sources as far as possible
3. The stable time of negative oxygen ion is 5-10min
