Design And Usability

All renewable dehumidifiers are built to be portable. Eva-dry E-333 versatile mini dehumidifier does it slightly better with its small and sleek ergonomic body.

It is also A/C compatible and will work as long as the temperature is not at freezing level. There’s even a sturdy hook that you can conveniently hang inside the wardrobe to keep your clothes nice and dry. Weight is only around 1 pound so no issue carrying it around town or pack it for travel in a high humidity area.

Safety-wise, Eva-dry E-333 renewable mini dehumidifier is designed leak-proof so don’t worry about any messy spill when you accidentally drop it. Even if an unfortunate event does happen, the silica gel beads are 100% chemical-free and are safe for children and pets. To further enhance its reliability and durability, Eva-dry comes with an industry-leading 5-year warranty with 10 years usage lifespan. Not bad for a moisture and mold removing device that only cost you less than 20 dollars.

Dehumidification Technology

A wonderful device that can keep indoor air dry and odor-free. For such a low price, Eva-dry E-333 wireless mini dehumidifier can quickly absorb moisture up to 6 ounces and covers up to 333 cubic feet of air room space. Perfect for an enclosed area where you can leave it untouched for days yet without the need for emptying the water. Eva-dry E-333 Wireless Mini Dehumidifier is also 100% cordless free and energy-efficient. It does not need batteries or an electricity cable to run. Just charge it once and the renewable dehumidifier can absorb moisture up to 4 weeks or 20-30 days. You will know it is time to recharge when the silica gel beads turn from orange to green. Find a power strip, charge it, and wait till the silica beads indicator change back to orange before using it. Note it may take some time though as ours took around 10 hours to complete the charging.

Eva-dry E-333 is engineered with a non-toxic, eco-friendly crystallized silica gel technology that protects your home from mold and corrosion. A desiccant, granular silicon dioxide made synthetically from sodium silicate. Each silica bead contains millions of tiny interconnected pores that form a large surface area to absorb and hold excess moisture. Most desiccant silica gel can adsorb about 30 to 40 percent of its weight in moisture through capillary condensation.
