Humidifying Air Purifier
The following situations have logical explanations.
Before requesting servicing, make the following checks.
Check

Does the unit have a humidifying filter?
Has scale accumulated on the humidifying filter?
Is the humidifying filter lamp lit or flashing?
Is the water supply lamp flashing?

Humidification capacity is low when indoor
temperature is low and humidity is high.

stops when the set humidity level is reached, but
air purification continues.
Is the unit exposed to direct sunlight or the hot
air draught of heaters?
Has the float inside the humidifying tray come off?
