Drainage Options
Your Wellsle dehumidifier offers two convenient drainage methods:

Illustration of manual drainage using the water tank and continuous drainage with the hose.
- Manual Drainage (Water Tank):
The unit features a 0.66-gallon (2.51L) removable water tank. When the tank is full, the dehumidifier will automatically shut off and an indicator light will illuminate. Carefully remove the tank from the front of the unit and empty the collected water. Reinsert the tank securely to resume operation.
- Continuous Drainage (Drain Hose):
For continuous operation without needing to empty the tank, use the included 3.28-foot drain hose. Remove the rubber stopper from the continuous drain outlet at the rear of the unit and securely attach the drain hose. Ensure the hose is sloped downwards to a suitable drain (e.g., floor drain, large bucket) to allow gravity to facilitate water flow. This method is ideal for high-humidity areas where frequent emptying would be required.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your dehumidifier.
- Filter Cleaning:

The dehumidifier includes a detachable and washable filter. It is recommended to clean the filter every two weeks or more frequently depending on usage and air quality. To clean, gently pull out the filter panel from the rear of the unit. Wash it under running water with a mild detergent, rinse thoroughly, and allow it to air dry completely before reinstalling. Ensure the filter is completely dry before placing it back into the unit.
- Water Tank Cleaning:
Clean the water tank regularly to prevent mold and mildew growth. Remove the tank, empty any remaining water, and wash it with warm water and a mild detergent. Rinse thoroughly and dry before reinserting.
- Exterior Cleaning:
Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
