Damp Check Non-Electric Dehumidifier

did not change the humidity in the room.

It eliminated.. musty smell in my basement .In a short time the salts were gone and the container was full of water

It's fascinating to watch the multi-colored mildew grow on the crystals - once assembled this dehumidifier works well and is an inexpensive solution to a temporary problem. If I had an ongoing problem, I'd buy a real dehumidifier, and as it is, I'll never buy this product again. It's difficult to assemble without getting the beads all over the counter - which is worrisome because I have no idea what sort of chemical this is, and if you get it on your hands, it leaves an odd dry sliminess that's difficult to wash off. The same is true for the liquid the product soaks up - again, amazing, it becomes full of water and can be surprisingly much fuller than you realize. The first time I picked one up to discard it, I ended up spilling some of the "water" on my floor, hands and clothes, all of which was difficult to wash out.Upshot is, it works. But it's chemically messy.
