Review on DEERMA 350G Portable Mini Dehumidifier: Renewable Silica Gel For Damp Air & Closet/Cabinet Moisture Absorber by Prem Reyel

My humidity monitor indicates these work well. I use one in a 10 cubic ft safe and 1 in a 13 cubic ft safe.I have them hooked up to a timer that runs 12 hours once per week in the humid Southeast USA. Funny thing is that when the moisture is cooked out (rejuvenate) it raises humidity in the safe during that period but it comes back down within a day. Be prepared to move them during rejuvenation if this will be a problem for you.Much easier than cooking my old desiccant canister in the oven every week.
