💧 Stay dry, stay sharp — the ultimate moisture defense for pros.
The Wisesorb 7 LBS 4A Molecular Sieve is a premium desiccant designed for rapid and efficient moisture absorption, capable of capturing molecules under 0.4nm. It operates effectively in extreme temperatures down to -20°C and can be regenerated by high-heat baking at 550°C, making it a sustainable and cost-effective solution for moisture control in industrial, scientific, and household applications.

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.

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…

Size reference needs improvement
For first time users, it will be best if they had scales shown next to the item. Picture and unit described it's hard for new users to understand how big the unit is. If item has been poured out of the container and placed next to a ruler, it will help the buyer understand better the size of these pellets.

Perfect of a damp car
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.

Better than advertised. Awesome!
4a molecular sieves Two experiments: 30 GM to start Poured 5x the apparent volume in water, fizzed. Dried3x on paper towels. Probably lost ~ 30 beads. Weight:40.41gm. Aluminum lasagna pan, convection oven set to 500c start time: 9:45pm. End time 10:45pm . After 1hr in oven weighed 30.4 GM. Put Hygrometer that reads down to 10% into polyethylene bag filled with air. Hygrometer read 40%. Added above cooked beads to bag and checked in morning. Hygrometer read 10% (lowest it could read).

Awesome product
I bought 3a and 4a from them, used them to dry solvents, leave in and store, and remove water from reactions. They work great. If I ever run out of them or find I need more than 7lbs in rotation I'd absolutely order more.
