Review: Dry filament - These dry beads have been a game changer for my 3D printing setup. If you’re serious about print quality, especially with filaments like nylon, TPU, PETG, or even PLA in a humid environment, proper moisture control isn’t optional — and these beads absolutely deliver. Since adding them to my filament storage bins, I’ve noticed a clear improvement in print consistency. No more random popping sounds, stringing caused by moisture, or weak layer adhesion. My prints come out cleaner, stronger, and far more predictable. For anyone who’s invested time dialing in profiles, you know how frustrating moisture-related issues can be — this eliminates that variable. The beads recharge easily and last a long time, which makes them cost-effective compared to constantly replacing disposable packs. I also appreciate that they work quickly. Even filament that had clearly absorbed moisture stabilized after sitting in a sealed container with these beads. Simple product. Massive impact. If you care about print quality and want reliable, professional-level results, these are a must-have. Five stars without hesitation.
Review: Dries well and color change indicator works very well - The blue desiccant silica gel beads work well to keep things dry. The very distinct color change is very helpful in determining when to re-dry the beads. I mainly use the blue desiccant in my AMS, and I've found I can go a long time before having to dry the beads. The bead size is perfect, with very few small particles that may slip through the desiccant screens or bags. I have completed three dry cycles on this batch already, and the beads are holding up nicely, so durability is not a concern. The bottle makes pouring easy, but I found that pairing it with a 3D-printed screw in a funnel improves the experience and minimizes spillage. There are concerns about the chemical used in the blue desiccant indicating silica gel beads, but I don't handle them often, and the particle size is large enough and heavy enough to not be an airborne concern.

## Questions & Answers

**Q: How many containers would i need for a 10x20x10 foot wtorage unit?**
A: All silica gel packets work in air-tight seal container. If they are open to air, they are constantly absorbing moisture in open air and become saturated right away. 
Please, keep them tight seal as much as possible. 
Information below lets you estimate how many grams of silica gel is needed at a given volume of your container. 
This is a general estimate when used in an air-tight sealed container. The amount of silica gel needed will depend on several factors: 
1. Chemical properties of the product that will be used: 
2. Volume of the container 
3. Conditions and physical properties of the container 
 
Container volume – packet size 
120 cubic inch - 1 gram 
240 cubic inch - 2 gram 
360 cubic inch - 3 gram 
600 cubic inch - 5 gram 
2 cubic feet - 30 gram 
4 cubic feet - 60 gram 
8 cubic feet - 120 gram 
64 cubic feet - 960 gram 

The storage unit volume is 2,000 cubic feet and this is too big for silica gel beads to cover.  
We would recommend using dehumidifier or storing items in a smaller container bins with appropriate amount of silica gel beads.

Silica gel beads are for an air-tight sealed environment. They continue to absorb moisture until they become fully saturated. They can bring the humidity level down to <10%.

Moisture absorber contains mineral salt named calcium chloride. These are ideal for small enclosed space like garage, basement, attic, closet, and etc..

Calcium chloride crystals absorb excess moisture in the air and brings the humidity level of about 50% which is an ideal and safe level. These crystals will slow down when the humidity level drops below 60% and will restart again when necessary. This is cost efficient, because the product will works when it's needed and not when it does not have to. 
However, calcium chloride is not reusable. 

Below are the ASINs for moisture abosrbers and hanging moisture absorbers.
B07JD85RM6 and B07K7YYVTV.  

Thank you.

**Q: anyone use tea bags to use the silica?**
A: Tea bags would work.  Many of our customers also use organza bags or women's hosiery, too.  Just a reminder, blue beads contain cobalt chloride. Our beads only contain 0.005% cobalt chloride.  Even though the amount is very minute, for safety, please, do not use for food or medication.  Thank you.

**Q: Can I use this to refill my Pure Wash cartridge?**
A: If Purewash cartridge uses blue silica gel beads, our beads will work.  If they don't work, please contact us.  We will issue full refund or send you a new replacement even beyond refund period.  Thank you.

**Q: can this be used in a 3 stage sharpe air dryer system?**
A: Yes, they will work for your air dryer system.
If they don't work, please contact us. We will issue full refund or send you a new replacement even beyond refund period.
Thank you.

### ⭐⭐⭐⭐⭐ Effective and Purdy
*by P***Y on February 19, 2026*

Work great and love the color. Using for my 3D Printer filament, gun safe, ammo boxes, even put a bunch in my freezer to help with the ice build-up. If you need to cut the humidity in a confined space 👍 good stuff.
