Wisesorb 40g Desiccant Canister

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!

I have a 24' civic and sometimes in Cali it can get cold at night, and condensation can form on the car. I've seen condensation also form inside the car as well so I thought buying this would help with helping get rid of the issue. To my surprise it does help get rid of a lot of moisture that was in the car when it gets really cold at night. For the price it's not bad. It gives you five so you can use it for other places if you need to.

These work great for keeping my ammo in there ammo crates really dry . They last for a long time when they turn green simple recharge and put back .

When it comes to my firearms and ammunition storage, I'm a little bit of a fanatic when it comes to quality. I received these and use them in all of my firearm and ammunition hard cases. I've also used them in file folder plastic containers where I store paperwork for my conceal carry classes I teach. I've ordered these multiple times. I've never had to recharge on (and hope I'll never have to). Because I haven't hard to recharge, or seen any water damage in any of the cases, I can't attest to their longevity. That's the ONLY reason I'm giving this four stars instead of five. I don't like when people post a five star review for a product they haven't yet used it its entirety. Those aren’t helpful in my opinion. With that said, I have a sense of comfort that these will protect everything within the cases in which I put them, which is why I've purchased these multiple times.

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.

Work very well

Worked very nicely, I used them for the AMS on a Bambu printer, I took out the beads and printed a container for them. It’s been about 2 months and they started turning blue, put them in the microwave and now they are back to bright orange. The AMS has a humidity sensor and it shows that with the beads inside there is low humidity so it seems to be working good!

Need to be recharged way too frequently! Feels like every other week they need to be recharged.

These are awsome. Keep your valuables dry and safe. Also reusable!

Tried these and they worked well. Problem is, they're not changing colour when I try and re-activate, this is frustrating. I assume they're not working after the first use then :-( Tried support and and I'm getting rote replys, very unhelpful and it takes days to get that......

These are working as described and are very useful - especially the way you can put them in the oven to refresh them.

The items match the description and the delivery time was exceptional. Cannot verify on the product's functionality until some time passes but feel confident.

Excellent! Work very well in removing humidity from car in the winter weather
