Hydrosorbent Silica Gel Dehumidifier 200 Gram Reuseable Best Deal

Silica Gel is a great product for keeping your valuables dry- such as tools, clothing, jewelry, guns, coins and other valuables. This product works well as represented. It is basically, nothing more than a sack filled with silica gel beads within an outer cardboard box. I use this to keep an area of about 10 cubic feet dry and it seems to be working effectively.
What many purchasers may not be aware of however, is that the silica beads are impregnated with cobalt (II) chloride hexahydrate which is used as an indicator for the presence of moisture in desiccants. The beads eventually will change color from blue to pink when moisture is present in the air, signaling that it is time to recharge the beads (shown by an indicator card resting on the bottom of the container). Unfortunately, cobalt chloride is classified as a carcinogen by the IARC, and it is both toxic and corrosive when exposed to water. Therefore, you should not tamper with or expose the beads to water.
Ideally, you should look for desiccants which use only non-toxic compounds for its indicators. I understand that other manufacturers now use an orange compound which is far safer than cobalt (II) chloride. I believe this warrants your attention before considering purchase.
PROS:
1. Extremely effective-Replaces units requiring power to reduce moisture.
2. Convenient Moisture indicator on box changes color when its time to recharge.
3. Extremely easy to use-simply open the bag-no other prep needed.
4. Very cost-effective: Much cheaper than purchasing other comparable products.
5. Product can be recharged and re-used many times by heating in oven for 3 hrs.@ 240 degrees F.
CONS:
1. Works slowly when used within about 5 cubic ft. of the rated ceiling range of the product. Better to purchase a larger size, especially given the cost differential.
2. The silica gel beads contain Cobalt (II) Chloride, a class 2B carcinogen.
3. Recharging process is time/energy intensive-3 hours in a 240 degree F oven.
4. If the box, beads and/or bag are compromised in any way, the product can lose effectiveness and can become a legitimate health and safety hazard.
