Usability

A vacuum cleaner company that has ties with Xiaomi, Deerma new renewable dehumidifier is their latest tiny invention. At 3 inches in diameter and 8.1 inches in height, it is very compact and portable despite not the smallest in its class. The 1.8 pounds weight is on the heavier side due to the leak-proof, spill-free, and high-quality ABS flame-resistant cylinder body. There is also a transparent visualization window that you can peek at to see if is time to recharge the mini dehumidifier. Recharge when the crystallized silica gel beads turned from orange to dark green.

Deerma Electric Mini Renewable is ideal for small spaces with mold and moisture issues like gun safe box, under sink, closet, wardrobe, pantry, shoe rack, jewelry box. The cordless setup means you can place it in the washroom, RV, car, and boat cabin with no restriction. The only letdown is probably the standard 1-year warranty which competitors model like Eva-dry offers up to 5 years.

Dehumidification Technology

Deermaelectric mini dehumidifier uses a familiar, renewable crystallized silica gel technology. A desiccant, porous granular silicon dioxide made entirely from sodium silicate. Each silica gel bead contains many hidden interconnected pores that join up to form a large surface area. Through chemical adsorption, moisture in the air will seep in and absorbed by the silica gel. It is estimated that each bead can hold up to 40% of moisture to its weight thus the extended 2 to 3 weeks usage time.

Protect and preserve your valuable items from rust and water damage. Deerma Electric Mini Dehumidifier is filled with a total of 600g dehydrated silica bead. It will give you a comfortable non reverse osmosis 2-3 weeks of moisture draining of up to 500 cubic feet before requires renewing. While it is not the quickest in reducing humidity and keeping the air dry, the wireless setup is well appreciated as no batteries or electrical plug is needed during operation. Unlike some mini dehumidifiers, you can use Deerma Electric in a vertical or horizontal position with Secure Horizontal Support yet without impeding the air inlet. Adding all that is the 3 PCS Ceramic PTC heating elements that help promote thermal conductivity and uniform heating. Charging time is a bit slow between 12-15 hours despite the advertised quick restore to dry status. During charging, you will need to keep Deerma Electric Mini Dehumidifier in a vertical position as the product may become hot with excess water expel out.

Price Guide

For around 20 bucks, Deerma Electric mini dehumidifier is a tad more expensive than the usual choice. However, you do get slightly more features out of it. It is definitely worth the extra few bucks but at the end of the day, it will function exactly the same as other renewable dehumidifiers. Give Deerma a shot if you want to try something new for a change.
Forget about your local retailers and official website, Amazon is the only place you could buy Deerma mini dehumidifier. It comes with hassle-free ordering, free shipping if the order is above $25, and 30 days no questions asked return policy. Unfortunately, there are very limited sellers carrying this brand so whatever discount you find on Amazon is probably the best deal. Do check back this section again and see if there are other means of getting one.
