Beurer humidifier's filter change indicator remains on even after replacing the filter.

Safety: No internal work is required for reset.

Steps:

• Perform reset: Consult the user manual for the specific reset sequence (often holding a specific button for several seconds after filter replacement).
• Power cycle: Turn the unit off, unplug for 1 minute, then plug back in and repeat the reset procedure.

If the indicator still does not clear, the timer or indicator circuit on the PCB may be faulty, but this does not usually affect humidification performance.
