Should I reset my Philips Air Purifier or Humidifier after replacing a filter?

Your Philips Air Purifier or Humidifier needs to be reset after each filter replacement.
This is done to activate the counting system for the new filter(s).

Also, your air purifier/humidifier is equipped with a filter replacement alert. It warns you
when the filter needs to be cleaned (pre-filter only) and replaced.

If you do not reset the air purifier or humidifier after replacing a new filter, the appliance
will alert you to replace a filter.

Can I clean the filters and pre-filter of my Philips Air Purifier?

You can clean or wash the pre-filter (indicated as C in the image below).

The other filters (indicated as A and B in the image below) cannot be washed: they need
to be replaced. Please check your user manual to see replacement indications specific for
your model.
