1 Quart Blue Replacement Desiccant Indicating Silica Gel Beads - 2 LBS Reusable by DRY&DRY

Good quality and good price

Does as described. Very effective. Can be re used multiple times.

What can you say about desiccant..It does what It was supposed to, I had expected the container to be larger by the image, but still the product seems to do its job well, my filament is drying out nicely.

I use this for my bambu p1s printer I printed fitted containers for the ams and with this product no issues with damp inc. the lustre filament that needs to be dry

I use these silica gel to help keep moisture away from my protein powders, as well as in my book cupboard and wardrobe. They seem to be working really well — I’ve already recharged them once, so they must be doing their job. The colour change indicator is a useful feature to show when the beads need recharging. Good value for the quantity provided.

Used these to trial a repair to a blown double glazed window unit. Drilled a hole in the corner and poured some in, then resealed the unit. If it works it would be a cheaper than replacing the unit.

Just what I needed for storing 3d printing filament below 25% humidity.

I have a moisture meter around where I use these. At first the moisture level dropped proving that they work, however the meter quickly showed it going back to normal with the beads NOT changing colour. Good job I have a meter becaise these don't tell you with their colour like they should.

Perfect for every use

I purchased two containers of blue indicating silica gel to support my 3D printing setup, and they've proven to be highly effective. I use them within the Bambu AMS unit to maintain optimal humidity levels for my filaments, as well as inside custom-printed containers placed directly in open filament spools. The beads consistently help keep humidity low, as confirmed by hygrometer readings. One of the standout features is the color-change indicator, which clearly signals when the beads are saturated. Recharging them is simple—just a quick cycle in the microwave—and they’re ready to use again. The reusability and ease of maintenance make this product a practical and reliable solution for filament storage. Highly recommended for anyone looking to protect their materials from moisture.

Muy buen producto, calidad por encima de otros que he probado, pero precio desorbitado, almenos en el momento de mi compra alrededor de 80€ + aduanas... Esto no quita que el producto es muy bueno pero considero que a ese precio está sobrevalorado. Si lo consigues más barato es un 10/10.

5 stars

Living with a 3D printer in a basement means fighting a constant battle against humidity. I bought this Dry & Dry Blue Indicating Silica Gel to keep my SUNLU PLA and other hygroscopic filaments dry, and it has made a huge difference. ​ Why This Works for Makers: ​ Clear Visual Indicator: The best part is the color change. In my filament dry boxes, it’s easy to look through the clear plastic and see when the beads turn from deep blue to pink. There is no guessing—when it’s pink, I know it’s time to dry them out. ​Industry Standard Size: The 3-5 mm beads are the perfect size. They fit into almost any 3D-printed desiccant pod or spool center container without falling through the vent holes. ​Truly Reusable: I’ve "recharged" these in a dedicated food dehydrator several times now. They go back to that bright blue color and work just as well as they did on day one. It saves a lot of money compared to buying disposable packets. ​ Heavy Duty: 2 lbs is a lot of silica. It’s enough to fill several dry boxes and keep a large storage bin at under 15% humidity even in my damp basement. ​ Final Verdict: If you care about print quality and want to avoid the popping and stringing caused by wet filament, just get this. It’s an easy, cost-effective solution that takes the guesswork out of filament storage.
