My Philips Air Humidifier does not reach the target level

If the room your humidifier is located in exceeds the maximum capacity for the appliance, your humidifier will not be able to reach the desired humidity level. Please see below for information regarding the maximum room size for your model:

• HU4803- 25 m2
• HU4811- 38m2
• HU4813- 44 m2
• HU4814- 40m2

When windows or doors are open, the humidity from your Philips humidifier will not remain in the room. 
To resolve this issue, please ensure that windows and doors are closed when the humidifier is in operation.

New furniture can absorb the moisture provided by the Philips Air Humidifier, and this can prevent the humidity in the room reaching the target level. Allow the humidifier to run for a longer period in order to resolve this issue.

Central heating systems may limit the ability of your humidifier to reach the desired level of humidity, by drying the air during the heating process. 

The display on your Philips Air Humidifier increases by 1 RH per second. Therefore it may take some time for larger changes in humidity to be reflected on the display.
