Cleaning the PM2.5 sensor of the Clean Air Optima® Air Cooler
Clean the air quality sensor every 6 to 8 weeks.
When the value of PM 2.5 is displayed incorrectly, a cotton swab can be used to clean the
sensor lens.
1. Switch off the device and pull the plug.
2. Use a screwdriver to take out the PM2.5 sensor
back cover.
3. Clean the sensor lens with a cotton swab and water as indicated by the arrow.
Then dry the lens with a clean cotton swab.
4. Install the cover of sensor.
5. Do not wipe the sensor lens with alcohol or other organic solvent.
Attention!
If the humidity in the room is very high, there is a risk of condensation on the air quality
sensor. This may cause the air quality indicator (Digital Display - Particle Measurement) to in-
dicate that the air quality is poor, while this should not be the case. In this case, we recommend
that you clean the air quality sensor or do not use the aircooler in automatic mode.
