If your Philips Humidifier or 2-in-1 Purifier & Humidifier does not humidify the air or you notice that the humidity indication/hygrometer does not change, find below how to simply solve this yourself.
The room is too big
There is a maximum room size that your Philips Humidifier or 2-in-1 Purifier & Humidifier can humidify. If you exceed the recommended room size for your specific humidifier model, the indication on your appliance or hygrometer will not change since your appliance will not be able to provide the expected results.
The humidification filter is not correctly assembled
The humidification filter should be assembled around the filter support. Your humidifier cannot function without it. Please make sure this is the case.
Note: The image below is generic representative, please follow humidification filter installation on User Manual specific for your model.
Doors or windows are open
When windows or doors are open, the humidity from your Philips Humidifier will not remain in the room.
Please close the doors and windows.
The humidity level is 70% or more
The most comfortable RH (Relative Humidity) level range is between 45% to 65%. For your health and comfort, when no target RH is selected (“---” displays on the panel), Philips Humidifier or 2-in-1 Purifier & Humidifier, humidifies the air continuously and automatically switches to the lowest speed once 70% RH level is reached. When environmental RH is lower than 70%, the appliance will resume according to previous settings.
If target RH 40%, 50%, or 60% is selected, the appliance also automatically switches to the lowest speed once the selected target RH is reached. When environmental RH becomes lower than the selected target RH, the appliance will resume according to previous settings.
This is a normal function and there is nothing wrong with the appliance. To find out more about RH setting, please refer to User Manual specific for your model.
The humidification filter is dirty
When the humidification filter is dirty, your humidifier cannot humidify. To solve this, please rinse the humidification filter. Remember that it should be cleaned regularly according to instruction on the User Manual specific to your model. If the scale has formed, descale it.
Note: Your humidifier has an advanced cold evaporation system, which produces healthy humid air from the outlet area without the formation of water mist. The water vapor is invisible to human eyes and does not wet the floor or desktop.
The water tank is not correctly assembled (Only applicable to AC3737)
Please make sure the water tank is correctly assembled on the appliance. The window of water tank and the display should be on the same side of the appliance as indicated in image below.
