Moisture is the enemy of optics and camera equipment because it causes rust, mildew, corrosion, and even nurtures the growth of lichens and mold.  Most moisture damage is caused by humidity trapped in a storage area, which turns into almost imperceptible condensation.  Hydrosorbent Dehumidifiers protect your valuables and supplies by ‘drinking up’ almost-indetectable moisture in camera cases, small cabinets and closets to create a protective shield of dry air in your storage areas.  This dehumidifiers work night and day, yet can be used indefinitely, buy it once, use it forever.  No electricity or other power supply, no refills and replacement parts are needed.  This dehumidifiers are non-toxic, no harmful vapors, no chemical reactions or stains.  Safe for foods, medicines, sensitive materials, electronics, clothing, collectibles, and more.

The 40 gram silica gel unit protects 3 cubic feet of enclosed space.  Top grade silica gel beads are contained within a compact aluminum canister that measures only 4" x 2" x ˝".  Provides lifetime protection for gun, camera and telescope cases, tool boxes, silver drawers, and more.  Each Hydrosorbent Dehumidifier has a built-in indicator that signals from blue to pink when it is saturated and ready to be reactivated. To reactivate your unit, simply put it in any conventional oven, so it can be used for a lifetime of moisture protection.

The more tightly enclosed and vapor-proof you can make the storage area being protected, the better! Position your Hydrosorbent unit on an exposed surface anywhere within the enclosed area to be protected. When you first use a Hydrosorbent Dehumidifier, it may become saturated rather quickly as it "drinks up" residual moisture. Once the residual dampness is removed by reactivation, you can maintain a dry condition with less frequent need to reactivate the silica gel.

- How to Reactivate Your Dehumidifying unit?
Examine the indicator from time to time. When the indicator changes from blue to pink, follow the reactivation instructions below.  Reactivation times below are minimums.  Sometimes, when the silica gel becomes overly saturated, it's good practice to extend the reactivation period. However, do not vary from the recommended temperatures.

When the blue silica gel beneath the inspection window turns pink, reactivate as follows: Place the unit in a vented 300 degree F oven for at least 3 hours (or until the silica gel turns blue again).

- What is silica gel and how does it work?
Silica gel was developed just prior to WWI and was used in Allied gas masks; then, in WWII it was used extensively to keep penicillin dry.  It remains the highest capacity adsorbent available today.  Not a "gel" as commonly thought of, and not to be confused with "silicon gel", silica gel is a porous, granular form of silica, synthetically manufactured from sodium silicate.
 The internal structure of each small silica gel granule is composed of a vast network of inter-connecting microscopic pores, which attract and hold moisture by a phenomena known as physical "adsorption" and capillary condensation.  A single teaspoon of Hydrosorbent Silica Gel has an internal "adsorptive" area equivalent to a football field, including the two end zones. 
Hydrosorbent Silica Gel is inert, non-toxic and safe to use to protect foods, medicines, sensitive materials of all kinds. Even when saturated with adsorbed moisture, silica gel looks and feels dry to the touch.
