Eva-Dry E-333 Renewable Wireless Mini Dehumidifier – 03-0681

The Eva-Dry E-333 is a small, cordless dehumidifier that uses non-toxic silica gel crystals instead of a disposable pouch, so you're not buying replacements every couple of months. It sits in a small space soaking up moisture, and when the crystals turn from orange to green it's telling you it's full.

At that point you plug it into a wall outlet for about 10-12 hours to dry the crystals back out, then unplug it and put it back to work. It never touches liquid water and there's no tank to empty, which makes it an easy fit for a closet, cabinet, or bathroom in a camper.
