Negative ion dust collection and purification method:
The negative ion electronic filter screen generates a large number of negative ions, which electrifies the particles in the air. The charged particles integrate with large particles to settle, so as to purify the air. The negative ions released to make the air fresh.
Advantages of anion purification:
1. The filter screen can be cleaned and reused without discarding.
2. It can purify very fine particle of dust.
3. It can effectively kill bacteria and viruses.
Disadvantages of anion purification and solutions:
Disadvantages: The CADR value is not high.
Solution: It is used in a small space with low purification requirements.
