Tosot Filter Clean Reminder

Dehumidifier displays CF after extended use; may continue to run but shows this reminder.

Possible Causes

Air filter usage timer reached preset hours, Dust accumulation on filter restricting airflow

Note: CF on many Tosot models is a maintenance reminder, not a fault.

Steps:

Remove filter: Turn off and unplug the unit. Slide out the air filter from the front or rear grille.
Clean filter: Vacuum loose dust, then wash with mild soap and warm water. Allow to dry completely before reinstalling.
Reset indicator: Press and hold the Filter or Timer button (varies by model) for 3–5 seconds until CF clears. Refer to your Tosot manual for the exact reset procedure.
