Should I reset my Philips Air Purifier or Humidifier after replacing or cleaning a filter?

Published on 07 March 2024

Your Philips Air Purifier or Humidifier needs to be reset after each filter replacement or after cleaning the pre-filter. To find out why, read our article below.

Resetting your Philips Air Purifier or Humidifier

The reset is done to activate the counting system for the new filter(s) and cleaned pre-filter (the filter surface is part of the pre-filter). If your Philips Air Purifier features humidification, the appliance needs to be reset after descaling or replacing the humidification wick.


Your Philips Air Purifier or Humidifier is equipped with a filter replacement alert which warns you when the filter needs to be replaced. Most of Philips Air Purifiers are also equipped with a filter cleaning alert which warns you when the pre-filter needs to be cleaned. Please follow the filter clean and replacement instructions in the User Manual specific for your model.
