Replace the filters in your C535

Reset the filter light
With the new filters installed and panel closed, turn the purifier on. Use a thin object such as a paper clip to hold the recessed Filter Reset button for at least 5 seconds, until the beep and the indicator goes out.
Do not wash the HEPA or activated carbon filters. The reusable pre-filter has separate cleaning instructions in the manual.
