Cleaning Air Quality Indicator

If there are dust or foreign objects in the particle sensor, the dust density may be detected high, so clean periodically to remove the dust. 

*If not cleaned periodically, the particle sensor performance will be degraded

*The cleaning cycle may differ depending on the environment. Clean more often in very dusty environments. 

*Do not let dusts drop into the air vent hole when you clean it. 

1.  Use a vacuum cleaner or soft brush to clean the dust outlet and dust inlet. 

*Use the lowest power of the vacuum cleaner to clean. 

2.  Clean the dust outlet and dust inlet with a wet cotton swab, then wipe it off with a dry cotton swab to remove moisture from it.
