Design And Usability

Eva-dry E-500 is a lightweight, portable, and renewable dehumidifier that delivers what it is supposed to do. At a sleek 5.5 inches diameter, 2.5 inches height, and a weight of mere 1.8 pounds, it is way smaller than its predecessor. The rounded soup shape design allows the versatility to place into a tight spot where even some mini dehumidifiers can’t. Eva-dry 500 is flexible enough to carry it around in the handbag, sweaty gym bag, or leave it in the wardrobe for days to come. It fits well in small spaces like a gun safe box, under sinks, closet, wardrobe, pantry, shoe rack, jewelry box, washroom, and vehicles such as RV, car, boat. The hanging hook is underappreciated on how useful it is in keeping your garment dry. You can even use it in a cold room with A/C turn on as long as it is not below freezing temperature. The perfect on-the-go device to keep things moist-free.

Another thing that makes Eva-Dry 500 cubic foot mini-dehumidifier great for everyday use is its build quality. Everything from the construction and fitting is flawless despite it cost less than 20 bucks. It is children and pet friendly with touted leak-proof, spill-free, and mess-free design. On top of it all, there is a long 5 years warranty that covers any manufacturer defects and poor workmanship. No other cordless humidifier offers something close to this.

Dehumidification Technology

Like the name implied, Eva-dry E-500 renewable mini dehumidifier is designed to cover 500 cubic feet of space with moisture absorbent between 6-8 ounces. Unlike a conventional thermoelectric model, you do not have to empty the water in Eva-dry E-500 ever. When the silica gel beads turn from orange to green, just find a power outlet and recharge it to clear out the collected water. There is no electricity plug or batteries needed after charged and Eva-dry 500 can hold between 30 to 60 days of water. While the cordless setup is cool, it does take quite a long time to charge the mini dehumidifier (up to 14 hours). It is also limited to close-range dehumidification due to its restricted capacity.

Powered by non-toxic, granular silicon dioxide made crystallized silica gel holds about 30-40% of moisture to its weight. The passing through water vapor will be absorbed and stored between the tiny passages of the silica bead pores. This process is called chemical adsorption and will effectively reduce the relative humidity level in an area. With reduced dampness, the renewable dehumidifier can safeguard household items from water damage, mold infestation, and corrosion.

Danby 30 Pint Dehumidifier is suitable to be used in the bedroom as it is considerably silent. The noise level is below 55 dB even at high-speed mode. You can place it near the bathroom and allow it to run through the night. As an Energy Star Rated unit, power consumption is also at a reasonable rate but unfortunately, we do not have the official figure. Rest assured it will not be too far off from the 30-pint model benchmark.

Price Guide

Believe it or not, Eva-dry E-500 is actually the premium version of a wireless dehumidifier. For less than 20 bucks, the renewable dehumidifier can be reused over and over again for up to 10 years. Outlasting most of its competitor models in terms of durability and lifespan. If you or your friends have trouble dealing with humidity and mold growth, Eva-dry E-500 can be the perfect solution.
