Camco Dehumidifier Moisture Absorber - Absorbs Up to 3X Its Weight in Water, Reduces Moisture and Humidity in Offices, Closets, Bathrooms, Kitchens, Boats, RVs and More – Refillable (44280)

I have a car that I don't drive much over the winter, so I usually put some of this stuff in the passenger compartment and the trunk. Seems to work well...I have to empty the container every week or two and there is always lots of water in it. As a bonus, it smells like fresh laundry...never a bad thing, given how bad cars, RVs, etc can smell after a winter of not being driven.

It keeps my storage room (which is not AC'ed, with only a weather-stripped door separating it from Florida's humidity) about 50% RH. Seems it keeps it at this humidity independently of how humid it it outside. So it definitely keeps the humidity under control. Great to keep our tools less exposed to moisture.

These work well for cleaning the excess moisture from the air. Surprisingly enough, the price is no better than you can buy locally at Home Depot. And, that is for the original brand name product.

Great, does the job perfectly. Saves the earth without having to throw out the whole plastic container each time it fills up

I use the mini dehumidifier in my truck camper. It does a good job absorbing the moisture; you can see it collect in the bottom of the container. I live in the desert which is normally dry, and left the dehumidifier in the camper all winter. Looked at it at the end of March and I was surprised to see water collected in the bottom of the container! Good product.
