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

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 ovenAlso, 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)
