I got this to use in the bathroom for summer humidity. It helps keep the condensation that collects around the toilet tank from pooling on the floor when the humidity is high. This was just the right size and price for the job. The unit was even smaller than i had expected but it works. It is about as loud as a fan when running. You can definitely hear it but it is an easy to ignore hum. I gave it four stars just because it doesn’t feel rugged enough to survive a fall from the counter. Normally that would not be a concern but i have almost managed to drop it twice when setting it up.
