1. UV: The main function is sterilization.
2. Activated carbon: Certain “carbon” -containing chemicals and organic substances in the air can interact with the activated carbon to be removed.
3. Static electricity: Electrostatic purifiers use positive and negative charges to attract particles in the air.
4. HEPA: When particles in the air pass through the filter, they will be caught between the fibers of the filter.
