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

Why did you pick this product vs others?:I vape in my house but needed something to catch the smoke since we moved into a non-vaulted ceiling unit and my cats were getting snuffly. I got those little smoke buddy type air filters and they get really soaked after a day or two, and are way to expensive to just keep buying. We put them in solo cups full of these beads and they do a great job sucking moisture out. Now instead of spending 40 dollars every week on new filters, I am able to constantly cycle them for months. So cool. Defrosting in microwave didnt really work well for me when recharging the beads but 250° in the oven brings them right back to vibrant blue. I love love love that these change color to indicate how much moisture they have sucked up; it gives you valuable information in that sense alone.

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.

Why did you pick this product vs others?:Seems to work well as a desiccant, after several months.The instructions for "recharging" them were clear and mentioned .5 to 2 hrs in the oven at 250. Took under a half hour before they were deep blue and ready to go again.

Works great in my air compressors dryer. Now I can cycle out the desiccant every other day.

Worked super well. Used it for my filament box for my 3d printer.

Great for my 3D printer, to help with reducing moisture on my filament

Bought these Silica Gel Beads to be used as a 3D Filament role center tube desiccant holder. The holder has 1-2mm slots all around. Shaking the holder after filling with these beads in the holder, nothing fell out, the beads are as advertised and very happy to see that. Will purchase again when needed!If size is a requirement for the desiccant beads being placed into your desiccant container, these will "fit" the need!Beads change to pink over time when moisture is present.

Great for filling containers and keeping things dry. Love the color changing aspect of it, making it very easy to know when its time to change out the desiccant.
