My Philips Air Purifier makes an unusual noise

When your Philips Air Purifier makes an unusual sound, there could be several causes. Learn more here.

The pre-filter may be clogged

Please, make sure the pre-filter is clean. If you need to clean it, you can follow these instructions:

  1. Switch off the appliance and unplug it from the wall outlet.

  2. Pull the bottom part of the panel (the front or the back part of your purifier) to remove it from the appliance

  3. Press the two clips down and pull the pre-filter towards you (see image below)

  4. Wash the pre-filter under a running tap. If the pre-filter is very dirty, use a soft brush to brush away the dust

  5. Air dry the pre-filter until it is completely dry.

Removing the pre-filter in your Philips Air Purifier

The filter packaging is not removed

When the wrapping plastic is not removed from a filter, this might cause an unusual noise. Please, make sure there is not plastic wrap left covering the filters.

Something is blocking the air inlet or outlet

The air inlet or outlet may be blocked by external objects.

Please check this and make sure the air inlet and outlet are unobstructed.

Your air purifier may be malfunctioning

If none of the above situations apply, then there might be a technical issue with your purifier. In this case, please contact us.
