To reduce this inconvenience, we advise you to discharge the appliance by frequently holding the tube against other metal objects in the room (for example legs of a table or chair, radiator etc.).
Furthermore we advise you to raise the air humidity level in the room by placing water in the room. For example, you can hang containers filled with water from your radiators or place bowls filled with water on or near your radiators.
If the above solution did not help to solve your problem, please contact Philips Consumer Care.
