Mini Dehumidifier WDH-898MD – compact & quiet
The WDH-898MD mini dehumidifier is a particularly compact unit featuring modern Peltier technology. It operates quietly and energy-efficiently without a compressor or refrigerant, making it ideal for cupboards, small rooms, motorhomes, boats, and other enclosed areas up to approx. 5 m².
With a dehumidification capacity of up to 750 ml per day, the WDH-898MD reduces excess humidity and helps mitigate condensation, musty odors, and a damp indoor climate. Thanks to the integrated humidistat, the desired humidity level can be controlled automatically.
Ideal for small and enclosed areas: The WDH-898MD is a practical solution wherever a large dehumidifier would take up too much space – for example, in closets, small cellar rooms, motorhomes, boats, or storage rooms.

Mini dehumidifier for closets, motorhomes & small rooms
The WDH-898MD has been specifically developed for applications where space is limited. Its compact design makes it a suitable mini dehumidifier for closets, small storage rooms, and other enclosed areas.
- Closets and wardrobes
- Small cellar compartments and storage rooms
- Bathrooms and small damp areas
- Motorhomes and campers
- Boats and yachts
- Small bedrooms and living spaces
- Pantry and storage rooms
The WDH-898MD is particularly practical wherever a conventional compressor dehumidifier would be too large, too heavy, or unnecessarily powerful.
Targeted reduction of humidity in small rooms
Humidity can quickly build up in small, poorly ventilated areas. This can lead to condensation, unpleasant odors, and, in the long term, an increased risk of mold. The WDH-898MD reduces excess moisture and thereby supports a drier indoor climate.
Automatic humidity control: The integrated humidistat enables demand-based regulation. This means the device does not need to be manually switched on and off constantly.
Peltier technology without a compressor
Unlike classic compressor dehumidifiers, the WDH-898MD operates using thermoelectric Peltier technology. As a result, the unit does not require a compressor or refrigerant. The compact construction allows for low weight and low-vibration operation.
Peltier technology is particularly interesting for small rooms and restricted areas of use. For larger or very damp rooms, however, a more powerful compressor dehumidifier is recommended.

Frequently asked questions about the WDH-898MD
Is the WDH-898MD suitable for closets?
Yes. Due to its compact dimensions, the WDH-898MD is particularly suitable for closets, wardrobes, pantries, and other small enclosed areas. It is important that there is sufficient space for air circulation.
How much water can the WDH-898MD extract?
Under optimal conditions, the WDH-898MD achieves a dehumidification capacity of up to 750 ml per day. At 20 °C and 70% relative humidity, the specified capacity is approx. 350 ml per day. Actual performance depends on factors such as temperature and humidity.
What room size is the mini dehumidifier suitable for?
The WDH-898MD is designed for small rooms up to approx. 5 m² or 15 m³. For larger rooms or severe moisture problems, a more powerful dehumidifier is recommended.
How loud is the WDH-898MD?
The specified noise level is approx. 46 dB(A). Thanks to the Peltier technology, the device operates without a compressor and is therefore generally low-vibration.
Can the WDH-898MD be operated continuously?
Yes. The WDH-898MD can be used for continuous humidity regulation. The desired humidity can be set via the integrated humidistat. When the water tank is full, the device switches off automatically.
Does the WDH-898MD help against mold?
By reducing humidity, the WDH-898MD can help avoid conditions that promote mold growth. However, existing mold is not removed by the dehumidifier. If there is severe or existing mold infestation, additional measures are required.
Does the WDH-898MD work with a compressor?
No. The WDH-898MD works with thermoelectric Peltier technology and operates entirely without a compressor or refrigerant.
