Dehumidifier displays CF after extended use; unit may still run normally.

Safety first: Turn the unit off and unplug it before removing the filter.

Steps to clear CF:

• Remove air filter: Slide out the filter from the rear or side of the unit according to the user manual.
• Clean filter: Vacuum off loose dust, then wash the filter with warm water and mild detergent. Rinse thoroughly and allow it to dry completely.
• Clean intake grille: Wipe down the intake and exhaust grilles to remove dust buildup.
• Reinstall filter: Once dry, reinstall the filter securely.
• Reset indicator: Press and hold the filter reset button (or as specified in the manual) for several seconds until CF clears.

Warning: Do not operate the dehumidifier without the filter; this can damage internal components.
