Remington Model 500 Mini-Dehumidifier (Sports)

My new closet is a large walk-in, opens to the master bath and I live close to the coast. A good friend warned me about mold in the closet and clothing due to those exact reasons as she had lived through it. She had a large window in her closet to air out her clothes and I do not. Did some research and decided on 3 of these Remington mini dehumidifiers. They are reusable for years, don't use batteries or electricity to run (yes, need electricity for the crystal refreshing) and are small in footprint. I believe they are working. I have had to refresh the units once a month since placing in my closet. The unsaturated blue silica crystals turns to pink when saturated with moisture. The legend on the front of the unit states then it is time to plug into an outlet for 5-8 hours to refresh the crystals to use again. So far, so good.
