Can a desiccant pack really absorb that much water? It was full in just two days. Could it be some chemical reaction turning the contents into water?

Desiccator boxes and desiccant bags are two different methods with the same purpose of dehumidification.

1. The desiccant in the moisture absorber will first absorb some of the water inside the wardrobe. When the internal humidity decreases, due to airtightness, there will be a humidity balance with the outside air of the wardrobe, and some external moisture will come in. This will actually absorb more moisture, resulting in more moisture, so it will be full quickly.

2. The calcium chloride in the moisture-absorbing bag itself can be used as a desiccant and has strong water absorption. The large amount of water should be because the calcium chloride has absorbed water and become a solution, which then flows to the lower layer in liquid form. Then the upper particles will continue to absorb water, eventually resulting in fewer particles and more liquid.

3. It is also possible that a hydrate, CaCl2•6H2O, has formed. A saturated solution should have formed. If the water in the container evaporates again, it becomes solid calcium chloride and will continue to absorb water.

Households often have moisture-absorbing boxes or dehumidification bags, which can dehumidify, especially in wardrobes or furniture, where placing some can provide a moisture-proof effect. Which is better, a moisture-absorbing box or a dehumidification bag?

　 Moisture-absorbing boxes are essential household items, especially in humid areas, where having one is very necessary. Moisture-absorbing boxes can prevent clothes from getting moldy and prevent wooden furniture such as wardrobes and tables from being corroded.

Dehumidification bags can be made of various materials, such as lime, coffee grounds, and activated carbon. Placing them in gauze bags, stockings, or cotton socks makes small dehumidification bags. Laundry detergent can also be used as a desiccant. Pour it into a used dehumidification box, poke a few small holes in the plastic film, and it can dehumidify. After it clumps, you can use it to wash clothes, without any waste.

Moisture-absorbing boxes and dehumidification bags are two different dehumidification methods with the same function. As for which is better, it depends on your choice.
