Surprised by how well this lowers the humidity in an enclosure. Be aware it is not as fast as silica beads, but is much more absorbent. I use this with a Powder Shaker (found on Amazon at www.amazon.com/dp/B0824XK6PN) for the center of 3D Spools in my Bambu Labs AMS. I also use both Silica Beads and this in a custom holder for dryboxes to store 3D spools.

Perfect for my 3D printer filament

I use this in dry boxes for 3D printer filament and it seem to get things to a lower humidity than the gel beads and packs I've used before. I have seen some types of beads swell and break into little annoying bits so I decided to give the alumina a try and glad I did.

These take my 3d printing filament storage and my AMS to levels of humidity that are lower than the sensors can reliably measure. They also last longer than the silica I used in the past.Finally a few hours in an oven recharges these so you don't waste money.A better value and better performance than silica!

These have worked much better than silica beads for keeping my 3d printing filament dry. They do make a little dust which I would avoid breathing when pouring them but otherwise perfect

I use it inside of my 3D printer and AMS and it has helped a lot with humidity.

This would be great desiccant however it was crushed. Therefore the seal was broken and moisture has been allowed. Yes they're rechargeable but that's not the point.

I purchased this based on a recommendation from a Youtube video, switching my silicate desiccant over to this.Super happy with the results! I have switched all my storage containers to it, and used tea bag strainer containers and placed them in the middle of my open filaments as well.If you use tea containers as holders, you can throw the containers in the oven too, and not have to dump out the alumina to dry it out.This has a HUGE difference over the silica, I get way lower humidity when it is fresh, and it lasts WAY longer between needing to be dried in the over.5/5, highly recommend this!
