    There is a constant or flashing light on my Philips Air Purifier

    Published on 07 March 2024
    If there is a constant or flashing light on your Philips Air Purifier, read below to find out the possible causes.
    When the filter needs to be replaced or cleaned, a light indication, icon or code will light up constantly or flash on your Philips Air Purifier. Once the filter is cleaned or replaced, please reset the filter lifetime counter (as indicated in the user manual). The light indication, icon or code will go off.
    If an error indication (E1, E2, E3, E4 or E6) is displayed, this indicates that there is a malfunction in your Philips Air Purifier. In this case, we advise you to contact the Philips After-Sale Service.

    Note: The error indication, filter cleaning and replacement alerts, codes and icons are different in each model. Please refer to the User Manual for your specific model.
