My Philips Air Purifier's airflow is weak and the light is not blue

If packaging remains around the filters, then you might notice weak airflow and the air quality light might not turn blue.

To solve this, please make sure to remove all packaging materials from the filters as shown in the following image:

A dirty pre-filter (C in the picture below) can also cause the airflow from your Philips Air Purifier to be weak.

Clean the pre-filter by washing it under the tap and letting it dry (it needs to be fully dry before it goes back into your purifier).

Dirty filters (marked as A and B in the picture, but some purifiers only have filter A) can cause weak airflow as well.

These filters should be replaced once a year or as recommended for your specific air purifier model, and they should not be washed.
