Eva-Dry EDV-E-500 Renewable Wireless Mini Dehumidifier Review

The Eva-Dry EDV-E-500 Mini Dehumidifier is different to any other cheap dehumidifier we have reviewed. It was designed to absorb humidity from small enclosed areas like closets, gun safes or travel trailers, helping to protect clothes, shoes, guns and other valuables from the damaging effects of mold and moisture rot.

This small dehumidifier is completely silent, has no power source or moving parts, no batteries or cords to plug in, so you’ll never have to listen to this unit hum away in the background. Just place or hang the Eva-Dry in a closet or other small enclosed spaces and it will start to absorb moisture.

There is an indicator window with special moisture meter crystals that are visible through a window that change color from blue (when dry) to pink (when wet) to indicate when the unit needs to be “renewed”. The Eva-Dry EDV-E-500 uses a specialized, engineered, crystallized silica gel that is odorless, non-toxic and completely safe. These “silica gel crystals” will adsorb approximately 8-10 ounces of moisture over a period of 6-8 weeks.

Once the Eva-Dry dehumidifier reaches its moisture capacity it will be noticeably heavier. It will not leak or spill at which time the indicator crystals turn pink so it is time to “renew” the unit. You simply remove the unit from where it was placed and plug it into a power outlet or power strip in a well ventilated area. The unit has a built-in heater that will warm the crystals allowing them to expand and release the moisture as water vapor into the outside air.

This takes about 12-14 hours to completely “re-new” the EDV-E-500. Once it is completely renewed the indicator crystals will change back to blue. The unit is brand new again and ready to adsorb another 8-10 ounces of moisture once again. According to Eva-Dry, these crystals will remain active for 10 years and Amazon offers a 5 year limited manufactures warranty on all EDV 500 units.
