The Sunpentown SD-350Ti is an extremely lightweight and small portable dehumidifier designed for easy transport and small areas. This model uses Peltier (Thermo-Electric) technology for whisper-quiet operation. The SD-350Ti is perfect for RVs, cars, nurseries, small bedrooms, closets, cupboards, cabinets, wardrobes, under sinks, laundry rooms, and any small space requiring dehumidifying. The SPT SD-350Ti is different from traditional machines in that it has no compressor, no refrigerant, and has no vibration. Another great feature of this model is that it has a UV light to sanitize passing air of bacteria, viruses, and mold spores. This functions automatically when the SD-350Ti dehumidifier is running. This model turns off automatically when the water tank is full to avoid spillage and comes with a transparent tank so that you can view the water level.
