Air purifier filters generate static electricity and interweave into felt after filtering hair, blocking airflow. When handling, you should cut the power first; it is strictly forbidden to dismantle the circuit part without authorization. It is recommended that a professional team use electrostatic dust collection tools to clean it, or replace the filter according to the original manufacturer's guidelines to restore ventilation efficiency.
Physical causes of filter blockage
When an air purifier is running, the fan creates negative pressure, drawing indoor air into the unit. The outer pre-filter is responsible for trapping hair, skin dander, and lint. However, these fibers easily generate static electricity due to airflow friction, attracting surrounding dust and weaving it into a felt-like layer, which severely clogs the airways and causes the unit's performance to drop.
Maintenance precautions
When handling the filter and internal air ducts, you must follow these safety principles:
- It is strictly forbidden to touch or clean any parts while the power is on.
- Do not attempt to dismantle the machine housing or electronic circuits yourself to avoid electric shock or damaging precision sensors.
- Do not use strong acids, strong alkalis, or non-factory-approved chemicals to treat the filters.
