In contrast to yesteryears compressor-based dehumidifiers, our dehummini uses advanced peltier technology. Ever heard of it; probably not, as it is whisper quiet. But quiet operation is just one of the many benefits of using this technology. It also allowed us to squeeze such a powerful and effective dehumidifying system into such a small package. Even more, it needs no moving parts to function, and that results in a lightweight machine sporting a longer lifespan. Small but powerful. Suitable for room size 9.9m. 0.5 L moisture extracted per day. Visible water level. Auto shut-off. Washable filter. Size H22.09, W12.95, D15.49cm.
