What filters should I use with my Philips Air Purifier?

If you are wondering which filters to use with your Philips Air Purifier, please see if there is an answer to your questions below.

Philips Air Purifier filters

Your Philips Air Purifier comes with multiple filters and will warn you when a filter must be replaced. When one of the filters is almost full and needs to be cleaned or replaced, the appropriate filter replacement light starts to flash to prompt you to replace that filter. That is how you will know which filter to replace.
