Question: What are the "crystals" made of?  Does this have activated charcoal?
Document: I really don't know how -- or why -- we did without these hanging in our closets. Living in the South, where humidity levels can be quite high, and in an old house which apparently traps moisture, nothing ever smelled fresh and clean in our closets. Then we tried these and have made them a routine part of our clothing maintenance. Nothing can take the 'old house' aroma out of our belongings, but eliminating dampness and mildew is a welcome effect of these hangers. When you open the careful packaging and hang the sealed white bag, you can feel the dry crystals through the paper pouch.
My house smelled pretty musty so I put 3 of these around the place. In a week everything smelled fresh and clean. The one in the closet made my clothes smell wonderful. No more mustiness!
We hung four of these in our cabin, and in three weeks they were completey full of water and all the crystals dissolved. Enough that we went to Lowe's and bought a dehumidifier. I bought a 4 pack at Costco for $7.99 and Lowe's has a 3 pack for $8.49.
This product is convenient with the hanger, the fresh scent is great, and it WORKS great in collecting the moisture! Easy disposal will be nice too when it is ready to toss away and replace in my car and closets. We've used the loose crystals in the open top container for years.... and happily, but this hanger is sooo nice!
I love these. Easy to use and work great. I have tried other DampRid products, and they weren't as good (the smaller tub ones). This one collects more water than I expected, and it is no hassle at all. I just hang it up, and when the crystals are gone, I throw it out. Easy, simple, convenient, and I can tell the difference in moisture (in the rooms I place them in) already.
After a week or two I started to see water build up in the bag. After about 2 months the bag was completely full of water and all the crystals were gone. The product does work as stated. As far the the odor it gives off, some people may not like it or could be over powering. I use it in a closet where there is a cat box and it does pretty good on helping to remove any odor.
I have had two of these bags leak, and now things in my closet are ruined!The way this system works is that crystals in the top part of the bag absorb moisture and then "melt" down into the bottom part of the bag. The combination of the moisture and the crystals creates a very greasy, viscous liquid that is stored in the bottom of the bag. If the bag breaks or leaks it is a disaster. Only use this in an empty space. I am so upset about the things in my closet that are now just covered in goo.
Weeks or months later, depending on your humidity levels, the crystals have magically captured the moisture in the air and deposited it in liquid form in the thick mylar pouch at the bottom of the hanger. When you go to check it, and feel the squishy, heavy pouch at the bottom, you know it has worked. We keep one in every closet, including off-season wardrobes in the attic, and just replace them as needed. In the meantime, they take up very little space on the hanging rod, and bless your clothing with a moderately subtle fresh scent.
It's very damp here. I have one of these in each wardrobe (7 of them), one hangs in the basement stairwell and I keep one hanging in my car. The one in the car helps with the window fogging. The one in the basement stairwell has reduced the mustiness greatly. I check these weekly to make certain that the crystals are not depleted and that the bags are not over-full. I don't want the bags to rupture and I don't know how freezing temperatures might affect them. If it looks like the catch-bag is going to be full before the crystals are depleted, I cut a small slit high up on the bag and squeeze the liquid out into the toilet.
works well and simply! hang it up and dome! have always used this damprid product for many many years in Tennessee
