desertcart.com - Wisesorb 40 Gram Pack of 4 Silica Gel Canister, Gun Safe Dehumidifiers (Orange to Green), Reusable Desiccant Moisture Absorber for Car, Closet

Review: Perfect for Filament Dryers — Reusable and Reliable - I bought the Wisesorb 40 Gram Silica Gel Canisters to use in my Kobra S1 ACE Pro filament dryer, and they’ve worked perfectly. They keep the humidity under 39% most of the time, which makes a huge difference in print quality. What I love: Reusable: Just dry them out and they’re good to go again. Practical for 3D printing: You can even 3D print a holder to attach them to the roof of the ACE Pro, which makes them super convenient. Great value: A pack of five lasts a long time and gives plenty of coverage. These are awesome little canisters and do exactly what they’re supposed to. If you’re looking for a simple way to manage humidity in a filament dryer, I highly recommend them!
Review: Works exactly as advertised—reliable and reusable - These Wisesorb silica gel canisters work exactly as advertised. I use them in my gun safe and tool cabinets, and they effectively absorb moisture without any mess. The color change from orange to green makes it easy to know when it’s time to recharge. I appreciate that they’re reusable—just pop them in the oven and they’re ready to go again. Great value for long-term moisture protection. Q&A Section: Q: How do you know when they need to be recharged? A: The beads turn from orange to green to signal it's time to recharge. Q: Can these be reused? A: Yes, they are fully reusable—just bake them at low heat to dry out the moisture. Q: Are they safe to use in gun safes and closets? A: Absolutely—odorless, leak-free, and compact enough for tight spaces. Q: How long do they last before needing recharge? A: It depends on humidity, but generally they last 2–4 weeks before needing to be recharged.

## Features

- 【Portable and Durable Silica Gel Aluminum Desiccant Containers】: Silica gel aluminum can is designed with convenience and durability in mind. Each canister measures 4 x 2 x 0.5 inches, providing a compact size that is easy to carry and store. The high-quality aluminum construction ensures the canister remains firm and sturdy, protecting it from dents and damage. With their independent and portable design, these small silica gel tin canisters are a convenient solution for your storage needs.
- 【Indicating Silica Gel Beads】: Wisesorb cobalt chloride-free orange indicating beads (2-4mm in size) are designed to change color within a humidity range of 20%-50%. Once saturated with moisture, the beads will complete the color change to LIGHT green. It's important to note that the initial color change does not indicate full saturation. The beads will continue to absorb moisture until reaching 50%RH. We recommend periodically checking the silica gel beads to ensure their effectiveness.
- 【Transparent Window & Easy Reactivation】: With the transparent window, you can easily monitor the color of the silica gel. If it turns from orange to light green, it indicates that the environmental relative humidity is above 50%. To reactivate the reusable silica gel canister desiccant dehumidifier, simply place it in the oven for 0.5 to 3 hours at 200°F to 250°F (avoid exceeding 250°F). The actual reactivation time may be shorter depending on the condition of the silica gel beads.
- 【High Absorbing Capacity and Versatility】: Our silica gel offers exceptional moisture protection for enclosed and sealed storage spaces of up to 30 cubic feet. Whether it's a safe, ammo cans, tool box, 3D printer filament storage box, weapon case, closet, or any other valuable storage container, our silica gel provides an effective solution to prevent moisture damage.
- 【Package Contents】: You will receive 2 packs of 40 gram indicating desiccant canisters. Each desiccant canister is individually packed in bags for easy storage. It is perfect for safeguarding guns, important documents, collectibles, books, jewelry, photo albums, shoes, camera lenses, expensive photography equipment, toys, leather clothing, ammunition, and photo equipment. Its versatile usage ensures the preservation and protection of a wide range of valuable items.

### ⭐⭐⭐⭐ Works as described and have several mounted in safes and storage areas that need less humidity.
*by D***N on January 4, 2026*

Have to recharge these frequently but work as described. If you have a need to have lots of these you might use the containers and buy bulk refills so you can store your wet ones in bulk and only recharge once a month. I purchased these and made them open friendly so I could replace the beads and save recharges to one time every 6 to 8 weeks. This plus a large container of the same type silica red green.
