Use the Eva-Dry EDV-300 Mini Dehumidifier to protect clothes and valuables from the damaging effects of mold, mildew and moisture rot. Six to eight ounces of moisture is absorbed depending on the humidity levels and this process should take about four to eight weeks. The crystals inside should be active for ten years if used correctly.

The Eva-Dry EDV-300 Mini Dehumidifier is a dehumidifier that does not use power, but uses specialized engineered crystallized silica gel that is odorless, non-toxic and completely safe. Once the moisture is absorbed by the dehumidifier, it cannot leak or spill. These moisture meter crystals change from blue (when dry) to pink (when wet) to indicate when the unit needs to be renewed. The unit takes about 12-14 hours to completely renew.

Review Title: Never regret this purchase
Comments: As full time RVers living on the Wet West Coast we have a lot of humidity. We had condensation in our closets,cupboards and under storage compartments. We ordered these for the under storage and one closet. They worked so well we ordered more, one for every closet and problem cupboard. Could not be happier with them and the fast and pleasant service we received. Order arrived in 3 days. We fully intend on purchasing from this company again and highly recommend them to all I meet.

Review Title: Eva-Dry EDV-300 Mini Dehumidifier
Comments: I am using these dehumidifiers in closets and I notice that the mold is coming back. Prior to these, I had been using the Stay Dry packets and they were working well. I had hoped to be able to cut back on the expense of replacing those on a regular, but it doesn't appear that these are working.

Comments: I have used the edv300 and am very pleased with the results. I use it to bring down the humidity in a desert terrarium and it works wonderful just set it on top of the terrarium and it will pull the humidity out of a small area quickly.

Comments: It does the job, and it's easy to see when it needs to be plugged in to dry out the crystals. I have never had anything that takes moisture out of the air be so small, yet work so well, with no mess or mold! I just love it. Thanks.

Comments: The product works really well. I placed it in a bureau where I store my sweaters. They have always smelled of mildew due to the moisture - after just a few days the smell is gone
