Wisesorb 2 LBS Activated Alumina, Alumina Desiccant, 1 Quart Reusable Desiccant Dehumidifier

So much better than silica beads. Absorbs more moisture and are very difficult to break. I put them in reusable tea bags and pop a couple in a vacuum sealed bag with the filament.

Sooo much better than regular desiccant . Reduced the humidity in my AMS to 10% and stayed there for a month,

Ideal for keeping filaments dry either in multi materials units or simply air tight boxes much better than silica dessicants.

These work great, ordered them for 3d printing and drying my filament, had to dry them out last week 40 mins in air fryer dried them out a treat. Probably not as good as their intended purpose but doing the job.

Solid, industry standard stuff. I’ve no complaints about the product itself, just keep in mind you can’t heat these up in your filament dryer or just leave them out in the sun to dry. Requires way higher temps to recharge, and while I don’t believe they’re toxic to be around, I don’t fancy alumina dust in my oven Also, there’s a printable funnel that fits the container perfectly, makes filling up AMS cartridges way easier. I figure Amazon blocks links, so if you just search up ‘7.5lb activated alumina pouring funnel’ you should find what I use. (Photo isn’t mine, but it’s what you’re buying + the funnel, credit @ it_works)

Works a treat in an AMS, went from having visible moisture on the inside of the AMS to having a reported humidity of 2%, it stayed there for a month or two in a humid utility room. To fill one of the AMS desicant holder prints (the one that fits at the back and between each filament at the front) you will use about 1 LBS of this desicant
