desertcart.com: Wisesorb 2 LBS Activated Alumina, Alumina Desiccant Great for Filament Drying, Reusable Dessicant Dehumidifiers Desiccant Moisture Absorber Prevent Wet Filament : Home & Kitchen

Review: Great for safes and 3D printers - Works great in both my gun Safe and 3D printer. Works just as planned and sucks up the moisture quickly and daily.
Review: Wow, really makes a huge difference. - It's more expensive and has no color indication so I was skeptical when I got this but figured I'd indulge my bougie impulses and they were well rewarded. I got these for my 3d printer filament dry boxes and it's night and day. I live in the EXTREMELY humid S. Eastern US where the LOW, indoor relative humidity is in the 60% range. Filament starts stringing like crazy after a few hours in the open. To test efficacy I used the exact same desiccant holders and swapped out the silica for activated alumina. My K2 Plus CFS used to bottom out at 15% RH with 3 separate added desiccant holders plus 4 in spool ones. My dry boxes were 20% Just using 2 of them but filled with this stuff took me down to 5% and whenever I swap spools, it gets back down to 5 much quicker. My dry boxes go lower than the minimum 10% my cheapy hygrometers can read. If you're concerned about color indication, don't mix the silica but instead they also sell RH test strips you can use. However what I've found by switching to this is the color does matter. Add desiccant until you reach the desired RH. Whenever that begins to rise it's time to replace/recharge it. The part we care about is the humidity and for filament or electronics, the color indicator shouldn't be what tells you that it's too high. It's also easier to 'recharge' as the color used for indication is toxic while activated alumina is pretty much harmless. While it's more expensive, you get a much better value for the money which does a better job and lasts longer. The filament boxes show petg. I had honestly just thought my hygrometers bottomed out at 20% until testing the alumina. Plus this Wisesorbent is cheaper than the other options.

## Features

- 【Activated Alumina】utilize premium quality raw material with an extremely porous structure and high surface area-to-mass ratio, high strength against crushing and very stable physical and chemical characteristics, even in high temperature and corrosive environments. At 77℉/25℃, RH90%, it can absorb more than 30% of its weight in water vapor. Each bead is 3 – 5mm in size.
- 【Activated Alumina】which has excellent porosity creating tortuous paths and extended surface area can be used in both heated and pressure swing dryers. It has stable physical and chemical characteristics, even in high temperature and corrosive environments.
- 【Activated Alumina】has a wide variety of applications, including compressed air and gas drying. In compressed air and gas drying applications, activated alumina can achieve dew points -100°F/-73℃, depending on the dryer. It is suitable for deep drying under pressure greater than 5kg/cm2.
- 【How to Use】: Place activated alumina into watertight dryer or container and then place dryer or container into the compress air or gas system. Desiccant Activated Alumina ( Aluminum Oxide) Desiccant is perfect for drying air and most other gases with relatively high humidity.
- 【How to Regenerate】: 1. Use the dry gas under lower pressure or higher temperature to pass the activated alumina. 2. Use wet gas which is heated or decompressed to pass the activated alumina. The reusable activated alumina beads desiccant dehumidifier can be reactivated by placing into the oven for 8 hours at 200°C-250°C (do not over 250°C).

### ⭐⭐⭐⭐⭐ Absorbs more than silica based desiccant
*by M***. on December 13, 2025*

Works excellent as desiccant for my 3-D printing filament. Better moisture control than the silica based desiccant. I wish it had an indicator to tell when it is absorbed all the moisture it could. For now, I mix it in a combination with color changing silica desiccant.
