Dry & Dry Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) - Reusable Desiccant Beads Silica Beads(Blue to Pink) - 2 lbs

I’ve been using the Dry & Dry [2 LBS] Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) as my go-to desiccant for the Bambu AMS, and it’s been a solid addition to my 3D printing setup. Living in a humid area, keeping filament dry is a constant battle, and these reusable silica beads have made it a lot easier to win that fight.The 2-pound jug is a perfect size for my needs—enough to fill multiple desiccant holders in the AMS without feeling like I’m rationing it. The beads are about 3-5 mm, which makes them easy to handle and pour into breathable bags or containers without spilling everywhere. I love the blue-to-pink color change feature; it’s a clear, no-guesswork indicator when they’ve absorbed enough moisture and need a recharge. In the AMS, they start off a vibrant blue, and over a couple of weeks, they gradually shift to pink as they soak up humidity from the filament spools.Performance-wise, they do the job well. Paired with a hygrometer in the AMS, I’ve seen humidity levels drop from the 40-50% range down to a steady 15-20% within a day or two, depending on the weather. That’s been a lifesaver for my PLA and PETG prints—no more stringing or brittle parts due to moisture. The fact that they’re reusable is a huge bonus. When they turn pink, I pop them in the oven at 225°F for about an hour (spread out on a tray), and they’re back to blue and ready to go. I’ve also tried the microwave defrost method for 10 minutes, which works in a pinch, though it’s a bit less consistent.The build quality feels reliable—the beads don’t crumble or turn to dust, even after a few recharge cycles. The jug itself is sturdy with a tight lid, keeping the unused portion fresh until I need it. One small quirk: the color change isn’t always uniform across all the beads, so some stay blue longer than others, but it hasn’t affected their overall effectiveness. Also, they’re not the fastest at absorbing moisture compared to some pricier options, but for the price and reusability, I can’t complain.For anyone running a Bambu AMS, these silica beads are a practical, cost-effective way to keep filament in top shape. They’re simple to use, easy to recharge, and have kept my prints smooth and consistent. Definitely a worthwhile pickup for any 3D printing enthusiast dealing with humidity woes.

Great value. I can tell these work. I do monitor moisture levels where used. Once implemented, humidity levels start dropping right away. Easy to read colors.

I got these to help keep my workshop at a low humidity for 3d printing (as most of the other people did as well). I have a thermometer and humidity gauge that I am using to monitor, and saw immediately just how powerful this desiccant is. I put one on the desk, and one in a 3d printed desiccant holder, the one in the desiccant immediately read 10% which is the lowest my humidity gauge can go. The overall humidity in the space started dropping as well, which I am happy about.I am impressed! Seeing much came in a 2 lb. package I was skeptical, but now I feel a lot better.

Needed it for a homemade filament dryer, and worked great. When it was time to replace it I followed the instructions to recharge them in the oven and the bright blue color came right back. Will buy again whenever they no longer do their job.

Absorbs moisture very well.

Working great so far, easy to tell when they are full of moisture. Laid then on a baking sheet and cooked for a few hours on lower heat, all dried out prefect.

Seems to work great. Does change color as it is supposed to.

Using for filament and seems to be keeping all my prints trouble free. Good stuff!
