    What filters should I use with my Philips Air Purifier?

    When you wonder which filters to use with your Philips Air Purifier, please find here if we can answer your questions

    Philips Air Purifier filters

    Your Philips Air Purifier comes with multiple filters, and warns you when a filter must be replaced: when one of the filters is almost full and has to be cleaned or replaced, the appropriate filter replacement light starts to flash to prompt you to replace that filter. That is how you know which filter to replace.
    Please find here what filter applies to your Philips Air Purifier

    Depending on the Air Purifier you have, you might see different types of filter replacement alert lights:

    A) Purifiers AC400x, AC401x, AC402x, AC407x, AC408x, ACP073x, ACP077x, ACP007x:

    • Filter replacement light 1
    • Filter replacement light 2
    • Filter replacement light 3/4
    • Filter replacement light 5

    See further explanations below.

    B) All other purifiers:
    Purifiers that do not belong to the list mentioned above, show a filter replacement alert light or an error code (models with a display panel).

    See further explanations below.

    When filter replacement light 1 flashes (in red)
    The pre-filter needs to be cleaned. You can wash it under running tap and dry it completely it before installing it back. Alternatively, you can clean it using a vacuum cleaner.

    When the filter replacement light 2 is on or flashing (in red)
    When the filter replacement light 2 flashes or is on continuously, you need to replace the multi-care filter (for Air purifier AC4004 only). This filter cannot be washed. After replacement, make sure you reset your appliance

    The filter replacement light 3/4 is on (in red)
    The filter 3 (activated carbon filter) and filter 4 (HEPA filter) need to be replaced. After replacing them, make sure you reset your purifier. Please note that these filters cannot be washed.

    The filter replacement light 5 flashes (in red)
    This light indicates that the humidification filter should be replaced.

    B) All other purifiers

    In this case (and for models without a display screen), your Philips Air Purifier has a filter replacement light. This light will stay on and be red.

    If your purifier has a display screen, then it will show one of the following error codes:

    Codes A1 to A9:
    Replace NanoProtect S3 HEPA filter.

    Codes C1 to C9:
    Replace the NanoProtect S3 AC filter.

    Code: F0
    Clean the Pre-filter.
