From The Manufacturer

This mini dehumidifier has been design to adsorb moisture from small enclosed areas (maximum area: 10’x 10′). It will help protect clothes and valuables from the damaging effects of mold/mildew and moisture rot. It is 100% renewable and needs no power to operate. Just hang the eva-dry unit in a closet, or you can place it in other small enclosed spaces, and it will start to adsorb moisture. There are no batteries required or cords to plug in, the unit works without power. There is an indicator window with special “moisture meter crystals” that change from orange (when dry) to green (when wet) to indicate when the unit needs to be “renewed”. The unit will adsorb approximately 8 to 10 ounces of moisture (depending on humidity levels this should take between 3 – 8 weeks). Once the moisture has been adsorbed it cannot leak or spill. This unit uses a specialized engineered crystallized silica gel that is odorless, non-toxic and completely safe. When the indicator crystals turn Green it is time to “re-new” the unit. Simply remove the unit from where it is adsorbing moisture and plug it into a power outlet.

Expert Reviews

What reviewers liked

Of the three smaller models we tested, the Eva-Dry E-500 removed the most moisture from the air, reducing the relative humidity by about 19% in about 1 hour and 40 minutes. The E-500 is especially portable because it doesn't require power to operate; it uses desiccant silica beads (like those silica packets that sometimes come with things you've just bought) that passively absorb moisture.
The smallest and cheapest unit on our list, this Eva-Dry unit is also our only desiccant pick – one that uses a special material to absorb water rather than secrete it into a container.
Reviewers say the Eva-Dry Electric Petite Dehumidifier does an admirable job reducing humidity in laundry rooms, bathrooms, and even RVs.

What reviewers didn't like

Unlike entirely non-electric dehumidifiers, the Eva-Dry does use electricity sometimes.
Of course, that means that this unit only works for very small spaces, but that may be exactly what you need. The unit is ideal for closets, pantries, and other tiny areas you want to keep as dry as possible. Note that you do have to plug the model in occasionally to help dry out the absorbing crystals.
At its low price, the Eva-Dry doesn’t boast a lot of extra features.
