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.

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