Dry & Dry" [1 Quart Premium Orange Indicating Silica Gel Desiccant Beads(Industry Standard 3-5 mm) - Rechargeable Silica Gel Beads(2 LBS)

I’ve been using the “Dry & Dry” Premium Orange Indicating Silica Gel Beads for a couple of months, primarily for drying 3D printer filament and keeping the air system on my compressor free of moisture. These beads perform incredibly well—they change from orange to dark green when they’ve absorbed enough moisture, making it easy to know when to reactivate or replace them.Reactivating the beads is super simple. I’ve placed them in the oven at 225°F for about an hour, and they come out as good as new. The convenience of recharging them instead of constantly buying new ones is a huge plus. However, given the price, they’re affordable enough to toss and replace if you don’t want the hassle of reactivation.The 8-pound jug is well-packaged and has an airtight seal to keep the beads fresh. The jug’s handle makes pouring out just what you need easy without spilling. The bead size is perfect for use in filament drying boxes or air compressor filters, and they’ve worked flawlessly in both applications for me.Regarding price, these silica gel beads are an excellent value. Whether you’re drying 3D printer filament, keeping tools rust-free, or maintaining an air compressor, they are a reliable and effective solution. I highly recommend them!

Keeps my 3D printing filament storage moisture free, even in a pretty humid environment. This small container of silica is enough for me to keep about six rolls of filament dry. The beads came intact, a very minimal amount of dust and broken beads at the very bottom of the container. A very cost effective solution if you're looking to keep storage containers dry.

This is a great solution for a 3-D printer filament storage case. Just 3-D printed a large container for it and now I have a way to keep all my filaments dry with a product that offers a visual aid to know when it's time to put the dessicant in the microwave to remove the water. Highly recommend!

Very quick delivery. Very good product. Dried my wet wood platter from 22% to 11% in 1.5 days

Came dry and sealed, I expected a bit bigger container than what I got.Other then that, great product

Perfect to keep AMS/filaments nice and dry in storage boxes.

I am using these to keep 3D printer filament dry, in large dry boxes. This desiccant works well, reliably keeps my filament dry box at 16-20% RH. when the beads start turning green, i put them in a glass bowl and microwave them on Defrost for 10 minutes and they're all ready to go again. Very easy. One word of caution, be careful when handling the beads. They're very slick, spill easily and bounce all over when spilled.

I previously bought some beads in plastic bags, but these loose beads seem much more effective at removing moisture. And cost effective.I have not re-charged any of these beads yet, but I'm pretty sure that the unwrapped beads will give up their moisture in a microwave far better than the bagged ones (the bags get all sorts of condensation on the inside of the plastic, but that condensation is still present and will reduce complete drying.
