SPT SD-300ML Mini Dehumidifier
Easily remove dampness from small areas with the Sunpentown Mini Dehumidifier. It quietly handles excess moisture in spaces up to 130 square feet.
Equipped with Peltier (thermoelectric) technology, this mini-dehumidifier works almost silently and without using refrigerant.
Compact and Efficient
The SPT SD-300ML dehumidifier measures about 9 inches high by 5.75 inches square, a perfect size to control dampness where larger, bulkier dehumidifiers won’t fit or are too loud. Since it uses no compressor, it operates whisper-quiet and ideal for use in these areas:
- Nursery
- Closet
- Small Office
- Storage Area
- Small Bedroom
- Poorly Ventilated Space
Near-Silent Thermoelectric Operation
This mini dehumidifier uses a thermoelectric heat pump to cool the surface of the interior metal cooling plate. As air flows over it, water in the air condenses, collects, and then drains into the collection bucket. Since it doesn't use a compressor, it's significantly quieter than standard dehumidifiers.
Additional Features
- Full Tank Indicator Light: A notification will turn on when the bucket is full. Operation will also cut at this point.
- Easy to Clean: This compact model is easy to wipe down. And no refrigerant means little maintenance.
- Automatic Defrost: Should frost form on the metal cooling plate, the unit will stop and initiate a defrost function. When defrost is complete, the unit will resume dehumidifying automatically.
