## Overview

The HYDROSORBENT SG-40 is a USA-made, compact silica gel dehumidifier housed in a durable aluminum canister.

Featuring an intuitive orange-to-clear moisture indicator and reusable design via oven reactivation, it offers a long-lasting, spill-free solution for preserving your valuables in style.

## Description

Hydrosorbent creates a 40 gram Silica Gel Dehumidifier desiccant unit which protects 3 cubic feet of enclosed space. It has top grade orange bead silica gel within a compact aluminum canister that measures 4" x 2" x 0.5". It has a built-in indicator that turns from orange to clear signaling a need for reactivation. This Silica Gel Dehumidifier can be reactivated in any oven with a lifetime expectancy.

Review: I've been using this for years. If you received a damage one, request a replacement for it or return it. With that said, these work great. I would "activate" them before using the first time and to keep them from opening (I dropped one before and the beads went EVERYWHERE), user a rubber band. Just remember to remove the rubber band before you put it in the oven to "activate." Also set a 4-6 month reminder (or whenever depending on how fast they absorb moisture for you in your situation), otherwise they will be less effective over time.
Review: I ordered eight of these for ammo cans. When I received these they had small dents in the metal, which I noted. I then reordered five more and they were packaged better and came in perfect condition. The orange light was not as noticeable as in the photograph. Everyone said you did not have to put these in the oven upon receipt. Just to be sure I put them in the oven for the required three hours. They are expensive, but if they last a life time and work well then I am willing to play the extra amount. By putting them in a small air tight ammo can, I would think that they would last a long time without having to reheat them in an oven. I have not had them long enough to be able to judge this.

### ⭐⭐⭐⭐ Review
*by E***R on 13 September 2020*

These seem to be working. But all five came in a sealed bag which clearly states that in order to remove moisture, they are to be placed in the over for 2-3 hours AND NOT EXCEED 200-240 F. The metal tins say 300F! So maybe it's because it's not the cobalt formulation? Maybe that's why some people experienced the window clouding? I don't know, but I relabeled my tins with a Sharpie staying in the 200-240 F range.
