## Description

Our Hydrosorbent silica gel dehumidifier prevents damage to cameras and other electronic equipment caused by humidity or moisture. These rechargeable dehumidifier silica gel units work by absorbing moisture from the air and preventing it from condensing on the surface of telescopes and other equipment.This pack comes with two mini canisters. They're reusable and proudly made in the USA.They can be regenerated by heating in an oven.The silica gel beads change color from blue to pink when they're full of moisture.These units will protect telescopes, cameras, gun safes, ammunition, clothes, leather, toolboxes, tackle boxes, and more. Silica Gel prevents condensation, rust, and corrosion in small, enclosed spaces.

Review: These work great. - First, there's a reason that all silica gel packs have a "do not eat" label on them. They're not good to eat, mostly because they are such good water absorbers. Similar to Portland cement in that respect. As to the cobalt scare? From the msds sheets on similar products, it's less than 1% indicator, and these are sealed up. Again, harmful level about the same as silica sand. (No kidding, play sand can cause silicosis.) You shouldn't pack this, or ANY non-edible desiccant directly in food. The aluminum isn't good for you, the silica gel isn't good for you, and none of the indicators are, either. Instead, pack the food in bags, then place those bags in another sealed bag with the desiccant. Anyway, these work great. I used them to keep 3-d filament dry, in mylar bags or metal boxes, and to keep electronics and photo equipment dry. They'll last longest in metal containers with good seals. Next best is heat sealed aluminized mylar bags. Next is probably heavy plastic containers. Worst is plastic bags. Plain plastic bags let a lot of water through, even if the bags are thick. How long do they last? Depends on the humidity. In the southwest, probably a long time. Up here in the north east? Not as long.
