    My Philips Air Purifier produces a bad or unpleasant smell

    Published on 07 March 2024
    If your Philips Air Purifier produces an unpleasant smell, there might be some possible causes. Find out here how to resolve this.
    The first few times you use your Philips Air Purifier, or use the heating function equipped (specific models only), it may produce a plastic smell due to the plastic materials of the appliance. Do not worry, this is normal and will fully disappear within a few days. However, if the appliance produces a burnt smell, we recommend you contact Philips After-Sale Service.
    When the inside of your Philips Air Purifier's filter (A indicated in image below) is dirty or when the filter has absorbed gases to its maximum capacity, it may cause a dusty odor. In this case, please replace the filter. To find the filter specific to your model please refer to your User Manual.

    When your air purifier's pre-filter or filter surface (B indicated in above image) is dirty, or not cleaned regularly, it may cause a dusty odor or bad smell. You need to clean the pre-filter or filter surface once a month or when indicated by the appliance. 
    Some models are equipped with a feature that purifies formaldehyde. The filter may produce sour smell when it absorbs too much formaldehyde. It is recommended to clean or replace the filter according to the filter cleaning or replacement indication. Depending on your household needs, you can replace the filter ahead of the indication if the sour smell is too strong and obvious.
    If the indoor humidity level is high, your filter could get damp and emit a strange smell. You can put the filter in a well-ventilated place for a couple of hours to reduce the smell.
    The information below applies only to the model AC3680.
    The hair removed from the pre-filter by the scraper is gathered in the pet hair container. Please ensure to regularly clean the pet hair container to prevent unpleasant odors. You can refer to the User Manual for more cleaning instructions.
    If the above does not answer your question, please contact us.
