My Pro Breeze Dehumidifiers do a good job for my bathroom but maybe not as you might expect. This unit can only extract water from the air if the temperature of the internal cooling plate is lower than the dew point. The bigger the difference the more water collected. If your room is cold, you’ll collect less water. There’s also less water in colder air.
This product had lots of reviews and I liked that the description explained what to expect from this device in performance on hvaclifehack.com . The wattage was 20 Watts, important in an RV. I would like to have seen a noise level listed.
