### ⭐⭐⭐⭐⭐ Perfect 3D Printing Dessicant
*by K***N on June 12, 2025*

This keeps my filament storage at <10% fast (sealed Sterilite container)Humidity in my area is between 40-50%, and an Eva-Dry 333 inside the box only kept it at 20%, even new.Haven't recharged them yet, but happy with drying performance so far.

### ⭐⭐⭐⭐⭐ Keeps my filaments drier than silica. Can be restored in microwave - but be careful
*by M***X on November 21, 2024*

I use it in a Bambu AMS to keep my printing filaments dry, and it does a *far* better job than the ubiquitous silica beads at that. Silica beads are bad at adsorbing moisture at low relative humidity; a few small baggies of this stuff gets the humidity down to around 6%.The beads can be dried in the microwave... CAREFULLY. I zap a small amount (50g - 80g) for a minute, take it out to dry, and do 2-3 more rounds of 30 seconds. This can remove several grams of water.Be very careful and work in small increments in power and time as they can get EXTREMELY hot. Hot enough that a supposedly heat proof potholder I put under the cotton baggie with the desiccant got charred and started smoking when I overdid it a bit on one occasion.

### ⭐⭐⭐⭐⭐ They work pretty good for my needs
*by D***S on July 30, 2024*

One of the main reasons I bought these was to dry was to dry my isopropanol for a capsaicin extraction and I got a very pleasant surprise when I was about to drive my isopropanol first it was exothermic meaning it generates Heat second it had some dust inside which you can see in one of the pictures once the dust settles it should be good to go besides the dust these are a great product and I would highly recommend them also there was a"sealed for your protection" pieces of paper on top but when I went to lift it off it just kind of blew away when I did it right next to my air conditioner so I'm thinking they're a little less dry than I originally thought also do not try to pour them into a small opening cuz when I tried it for my bottle they spilled everywhere but I would say these are pretty good product oh if you're trying to pull out water from a chemical then use 3A
