Document: work well. used in the refrigerator, it actually work, dehumidified the moisture in frig. it prevents my food from getting moldy fast.
I put these in two closets, not expecting much. In one closet the moldy smell is completely gone, in the other, which has a worse problem, very much improved. I like that they don't use (continual) electricity or chemicals, too.
I have a closet on the ground floor where the air has been feeling a bit damp and smelling just a little moldy since this spring, when we had such heavy rains that even the ever-present bucket of Damp-Rid wasn't able to keep up. As spring turned to summer, I kept thinking that the problem would take care of itself, but it didn't.
I've been discovering moldy clothes in my closet for years and having to get rid of some and dryclean some; they all still smell somewhat.Then I got this product for my closet and it's been amazing. No moldy clothes yet, and I can feel the difference in the closet. This puppy works overtime!Plusses: Renewable. Does not require the same resources as Damp-Rid. Works better than Damp-Rid. Easy to use.
Good so far. I use it in my small walk-in-closet. I air dry some clothes in there. The clothes are mostly dry by the first day. It gets away the humidity pretty fast. Within a few days the dehumidifier starts turning purple-pink. When you plug it in after about a day-day and 1/2 it starts getting warm and it eventually goes back to being blue.
OK, this product sounds great, and it is, but only for the things it's actually made for ie. small enclosed spaces and not entire rooms.I bought the smaller version for a small safe (about 1.5' square) I have that was always getting humid and allowing my documents to get moldy. In two days the relative humidity went from 67% to 38%. Two more days and the musty smell disappeared. After a month the indicator crystals are still pretty blue.
We have a safe and used to have trouble with our documents getting a musty smell. I bought this mini-dehumidifier and it solved the problem. I like that all you need to do to renew it is plug it in for awhile. It's saved me from making additional purchases.
Comes sealed so you don't have to 'recharge it' which was nice, comes with a nice hook to hang in your safe/closet/etc and after testing in a humidor (only way I had to test it effectively) it dropped humidity fairly quick, recharged and was good to go again!
Love how this product works. No more moldy smell in the closet. Service was fast. Would highly recommend. Should have got more, might still.
I had to do something. We nearly lost one set of Western reins because our Midwestern summers are extremely humid, and our tack room is not air conditioned. So we bought the Eva Dry 300/E-333, just laid it up against the side of our tack closet close to our reins, check it regularly, renew it when required, and voila! No more moldy reins!!
Answer: I have a safe roughly of those very same dimensions and this works just fine (going on three years of use now absent any humidity issues whatsoever). Difference here is I am combating moisture buildup on metals and documents, not food. That said, if I had a situation like your's I would use them without hesitation.
