Review: Excellent Moisture Absorption for Filament Storage - I’ve been very impressed with the Slice Engineering 2lb Activated Alumina Desiccant. It arrived quickly and the container makes it easy to pour and refill smaller holders without making a mess. Compared to orange indicating silica gel, this absorbs more moisture and seems to last longer before needing to be recharged. The tradeoff is that it does not change color, so you will want to monitor humidity levels with a hygrometer rather than relying on visual indication. I use this in 3D printed spool desiccant containers and in my AMS desiccant holders, and it has worked extremely well. Humidity stays low and filament performance has been consistent. To recharge, I dry it in my AMS HT using a high temperature safe container at full temperature for a couple of hours, and it is ready to go again. If you want a higher capacity desiccant solution for filament storage, this is a great option and I would definitely recommend it.
Review: Very effective at removing moisture - I switched to activated alumina for my 3d printing needs and don’t regret it. Sure it’s more expensive than silica per pound, but this stuff works really well, and I find it keeps moisture levels lower for a lot longer than silica did. There’s no color change to indicate it’s time to dry it out, but I’m running a hydrometer for that. I don’t have to worry about the toxicity of the chemical makeup when cooking off the moisture to recharge like I did with silica. I ended up buying a second 2lb bottle, as one contained a little more than what fills up all the dry pods in my BambuLab AMS + 4x reel pods. So now I can dry/recharge a batch ahead of time and swap it out quickly to minimize the time it’s exposed to the open air.

## Features

### ⭐⭐⭐⭐⭐ Great. Desiccant
*by B***L on October 9, 2025*

This desiccant works great, keeping the relative humidity in my AMS so low that my gauges read only 10%, which is the lowest the indicator will read. My models are excellent, and the filament is dry as can be.
