Review: This should be the standard for 3d printing, not silica - This stuff is great, it works very well. People should use this over silica for 3d printing. It keeps my 3d printer AMS at <10%. **I tested and found it much easier to use - to recharge it at 200C for just 3 hours.** The directions say you need 550C for 2 hours. To get that hot requires some specialized lab equipment. Again, I found that unnecessary. The important thing about Mole Sieve is that it does most of its moisture absorption before you hit 15% vs Silica. Silica can hold more water but only if you're looking to limit the humitity at higher RH. So if your goal is to keep your dry box or enclosure at 50% RH or less then silica is better. I try to keep things more like 15% or less and mole sieve is 3x more effective in this range. Or conversely, I'd need 300g of silica to do the same thing that 100g of mole sieve does. It makes changing desiccant out simpler too. If you start hitting 10%, just swap it out, its done all its work already and needs to be recharged.
Review: Outstanding product and at a good price. - Best thing ever created if you want to test if they still got absorbtion in them put it in your hand wet ur finger and touch them if they get hot they are still good but be careful I squeezed them and it almost burned my finger. They are great for dehydrating mushrooms after the dehydrator this bad boys will pull that little moisture left for the longest shelf life possible

## Features

- 【3A Molecular Sieve】: 3A molecular sieve desiccant is a type of compound aluminosilicate desiccant whose effective pore size is 0.3nm. It is mainly used to absorb water and does not absorb and molecular larger than 0.3nm. Its application characteristics in industrial use are: rapid absorption seed, a mass of reusable times, strong anti-crash strength, and strong anti-pollution ability, which improves the use effectiveness of molecular sieve and extends its service life
- 【Complies with Industry Standard, Strict Quality Control】: Wisesorb 3A molecular sieve desiccant goes through strict quality control process before they are released from the factory. It complies with molecular sieve industry standard and ensure that every bottle if product are qualified and has premium quality
- 【Rapid Moisture Absorption, Reusable】: Wisesorb 3A molecular sieve has strong moisture absorption ability even under low temperature and low humidity rate. At the time, it still possesses certain moisture absorption under high temperature . It can be reactivated when dried under 550°C
- 【Wide Range of Use】: Pore size of 3A molecular sieve is 3A, which is applicable for drying of all types of air, hollow glass, refrigerating fluid, natural gas, methane, unsaturated hydrocarbon, pyrolysis gas, ethylene, acetylene, propylene, butadiene, etc. The date printed on the package is the manufacturing date not the expiration date
- 【How to Reactivate & Independent Packaging & Package Includes】: 3A molecular sieve can be placed in a muffle furnace and baked at 550°C (1020℉) for 2 hours, then transferred to a drying cylinder, and cooled to room temperature for use. 3A molecular sieve beads are stored in one plastic jar for long-term preservation & protection & store. Package includes 1 packs. The wide mouth jar makes pouring the sand back in extra easy

### ⭐⭐⭐⭐⭐ Works great for keeping 3D printer filament dry.
*by A***. on June 12, 2026*

I replaced sillica gel with this 3A zeolite in the airtight container I use to store my filament. The RH dropped from 20% to 11%, so I'm satisfied.
