Review: Excellent for 3D printer dry boxes - Totally glad I went with this for my 3D printer needs instead of regular silica. These small beads do a great job of drying my filament in my AMS and enclosed filament box. I use hygrometers to check if moisture is starting to accumulate and after 4+ months it still hasn’t. I never have print failures due to filament issues. I am still fairly new at 3D printing yet I am pretty convinced that using dry filaments is so helpful for good adhesion and quality prints. This is a large container too. I have filled up many intra-filament spool dry boxes and the container is still 1/2 full. I know it is harder to regenerate/dry molecular sieve but I will figure it out when I get to it. Right now it seems like it will be many, many months to years from now…
Review: Great Buy on such a large amount that you get. - These are the same size desiccant beads that are in my moisture filter, which I use with my CS GX4 PCP compressor.

## Features

- 【13X MOLECULAR SIEVE】: 6lbs molecular sieve is made using high-quality raw materials, 13X molecular sieve. This alkali metal aluminosilicate has a pore size of 1nm, allowing it to adsorb molecules smaller than 1nm. It serves various purposes such as a catalyst carrier, co-adsorption of water and carbon dioxide, and co-adsorption of water and hydrogen sulfide gas. Under conditions of 77℉/25°C and 20% RH, it can absorb over 20% of its weight in water vapor. Each granule is sized 1.5-2.5mm.
- 【HOW TO USE】: Simply place the 13X molecular sieve granules into the desired enclosed storage space. Allow the molecular sieve to work its magic until it reaches its maximum adsorption capacity. When it is time to replace the molecular sieve, simply remove the old granules and replace them with fresh ones.
- 【REACTIVATION】: To reactivate the 13X molecular sieve granules, follow these steps: Place the granules in a muffle furnace and heat them at 550°C (1020°F) for a duration of 3 hours. After the baking process, transfer the granules to a drying cylinder. Allow the granules to cool down to room temperature. The reactivated 13X molecular sieve is now ready to be used again.
- 【EASY-TO-POUR】: Our easy-pour can combines capacity and control for your convenience. With a multi-pound volume, it holds a generous amount of desiccant beads, making it ideal for various applications. The can features a unique handle design that ensures easy carrying and pouring. The dual-handle design allows for multiple hand positions, offering better maneuverability and enhanced control during use.
- 【BULK BEADS WEIGHT】: Our 1-gallon package contains 6 lbs of desiccant beads. Please note that these beads are not suitable for drying flowers. For effective use, you can place the beads inside various containers such as a fine mesh food straining bag, mesh bag, T-Sac tea filters, tea bags, drawstring organza bag, muslin bag, mason jar, dryer containers, knee-high nylon stockings, clear plastic storage bin, mesh laundry bags, or women's hosiery.

## Questions & Answers

**Q: How do I reactivate the 13X sieve?**
A: My research online found that thinly spread out on a foil lined cookie sheet @ 500 degrees for 2-3 hrs. should work.13x sieve takes a higher temp. to evaporate the moisture.I have not done this reactivation method yet but this is what info. I have found. Use at your own risk!

**Q: This 13x is very coarse compared to my oxygen  concentrator, can i grind it in a grain grinder?  I refilled it with 13x, now my concentrator is n/work**
A: Yes, you can.

**Q: Does anyone know the mesh size for this material?**
A: Caliper measures average around 0.09".....so mesh size will be around 8........but the one I actually ordered is 4A......not 13x

**Q: does it come with a material safety data sheet (SDS) from the manufacturer?**
A: A SDS can be provided upon request, to request one please send a message to the seller.

### ⭐⭐⭐⭐⭐ Perfect of a damp car
*by R***H on January 26, 2025*

This product sucks up the humidity in my car aggressively and reduced the damp, musty smell to almost non-existent... I wish I had found them sooner but glad I did and it works. Probably good for gun safes in a basement too.
