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

Get this and you won't need to ever buy more again. I use these to keep my filament from getting moisture in them. I check them about once a month and dump them in a bowl, put it in the microwave for about a minute, stir, and keep doing this till they get back to their original color. BE VERY CAREFUL, THEY GET HOT AND WILL STICK TO YOUR FINGERS WHEN YOU GET THEM OUT. It's like having little balls of lava on your finger. Use a spoon to stir them.

I had no real confidence that this would work, but when there was a LOT of moisture condensed on the inside of my phone's camera lenses, I took a shot. I poured a 2 lb jug of these desiccant beads into a gallon Ziploc bag, powered down my phone, threw it in the bag the beads, squeezed the air out, sealed the bag, and left it alone for about 30 hours. Lo and behold, everything is back to normal! It's like I never dropped my phone in the bathtub. I can't believe how lucky I am. I 100% thought I would have to get a new phone. But nope!

This desiccant has worked well for a couple of years keeping my 3D printer filament nice any dry. The color charge is very easy to see and it "recharges" easily in the food dehydrator that I also use to dry filament. When I need more desiccant I'll be back to this listing again.

Works great, and the bottle seals well after opening to ensure it stays fresh and moisture free. I use this with my 3D printing filament, and it keeps everything perfectly moisture free. Highly recommended!

These work great at pulling the moisture out of my AMS for my 3D printer. Worth the buy!

Refreshing these using a microwave can be hit or miss. From a microwave, if a large porcelain plate isn't used, it seems difficult to dry these back to orange. In a thick glass cup, it will dry it out and you can hear and see the moister boil away but if you use it for the recommended 2 minutes, it can and will most likely crack your class container. The filament dryer doesn't seem to get hot enough to dry these though.

This works great. I like how easy it it to know when you need to recharge the desiccant.

I use this in printed dessicant holders in my 3d printer AMS units. It works great. Reusable by baking in the oven for a short time at a low temp (or in the microwave). Not hard to use at all. Perfect size for printed dessicant containers.Affordable and durable.
