wisedry [ 5 LBS ] Silica Gel Beads Reusable Color Indicating Rechargeable Desiccant Bulk with 12 Pcs Organza Drawstring Bags

I’m currently deep into setting up a more permanent moisture-control system for my 3D printing filament, and this 2lb bag of Wisedry was exactly what I needed. If you're printing with anything hygroscopic, you know that keeping your storage environment under 20% humidity is the goal, and these beads make that pretty effortless. I was actually surprised by how far 2lbs goes. I managed to completely fill the desiccant center-pods for my AMS 2 Pro, and I still had enough left over to outfit several of my Wildone cereal box dry containers. I’ve only used about half the bag so far, and my entire setup is already protected. It’s a much better value than buying those tiny individual packets that you have to throw away. Color Indicating: The fact that they change color when they're saturated is a total life-saver. There’s no guessing game; I can just glance at my dry boxes or the AMS and know exactly when it’s time for a refresh. Rechargeable: The big selling point for me is that these are reusable. Being able to just "bake" the moisture out and start over is way more sustainable and cheaper in the long run. Bead Size: The 2-4mm size is perfect. They’re large enough that they don't leak out of my 3D-printed desiccant holders/adapters, but small enough to pack in tightly for maximum surface area. I’m really interested to see how many "life cycles" I can get out of these before they need a full replacement, but so far, they are performing perfectly. My humidity levels dropped significantly within just an hour of putting them in. If you're a maker looking to protect your filament investment, this is a solid buy.

This is a lot of freaking beads. I use it in my secret safe to keep my hoard dry. It works well and they are easy to recharge. I put them in a toaster oven with a convection setting and it dries them right back out. Don’t spill them because they will go everywhere and you will never get them all back.

I use this desiccant to help keep my 3D printing filament dry. I had some similar desiccant that came in some small sealed plastic boxes and it worked well, but after several rejuvenation process in the microwave, I melted the original boxes and many of the beads had shattered. It seems that these are able to be dried out, but over time the start to break down. This doesn’t bother me, because I consider dessicant to be consumable product. If I can reuse it a few times, it’s great, but ultimately I don’t plan on it lasting forever. This huge bottle comes with a lot of bags, but I haven’t used them yet since I make my own holders on my printer. I made a bunch of containers out of clear material and fill them up with a funnel. I left one of the little boxes outside of a sealed container, and within two days, the orange beads had turned green because I live in a high-humidity area. I opened the container and poured the beads into a coffee cup and stuck it in my microwave. It would probably be better to use an oven with constant heat instead of a microwave to make the beads last longer, but I was going for fast. I did three cycles of 30 seconds on high, stirring the beads between each cycle. After one minute 30 seconds, the green beads had turned orange again and they were slightly sticky from the moisture that had been expelled from them. I let them cool down and get dry again, then poured them back into my container. None of the beads had broken, but I’m sure that if I microwave them a couple more times, they will start to fracture. They might last longer if if use an oven. This is a huge amount of reusable (at least a few times) desiccant. It keeps my filament nice and dry. I have a humid sensor in one of my storage boxes, and it indicates 10% relative humidity which is as low as it can display, so it’s likely lower than that.

I’ve purchased this desiccant multiple times, and it’s become my go-to choice. I run a Bambu X1C with multiple AMS units, and I’ve fully replaced the stock desiccant with this. It fits easily into printed holders, and I also use it in printed containers for individual filament spools. The performance has been consistently solid. It recharges cleanly, dries evenly, and stays dry for a long time once sealed in the AMS or spool container. The green indicator beads make it obvious when it’s time for a recharge, which takes the guesswork out of moisture management. Across multiple AMS units and frequent filament swaps, this desiccant has kept humidity under control and helped maintain reliable print quality. For anyone running a Bambu setup or wanting their spools to stay dry when stored, it’s a dependable, cost‑effective choice.

These silica gel beads work great at absorbing moisture. We put a few satchels in each of our moving boxes and it kept everything dry on a cross country move through snowy weather! The only downside is that they take quite a long time to dry out (we put the beads on baking sheets and fried them out in our oven on the dehydrating setting), it’s kind of hard to tell when they are full try since they don’t all dry out evenly, and the little bags it comes with shed everywhere. Next time we use them we will try to find different pouches to put them in.

I needed better desiccant that I could reuse and didn’t off-gas the toxic fumes I hear about. Its primary use is in a Bambu Lab AMS unit. I was able to print and fill containers with the desiccant and it is still going strong several months later. The color changes when it’s ready to be recharged. To recharge it, the media needs to be heated. Following directions it’s quick and easy. A word of caution. Don’t use ovens or anything that will see food cooked in it. It should only be heated in and oven that won’t be used for heating food.

So far this has kept my filament down to 10% humidity and seems to work well.

Important stuff first: PROS: - They appear to work as promised - Good quantity for the price - Can last a long time if properly cared for CONS: - Beads are hard to control and if you don't have a good container for pouring into pouches they are going to go everywhere. - Orange beads will turn green well before the beads are "full". I don't have the timing down, but looks like the are still good for a few weeks after the orange beads change color. - You have to recharge them (or more accurately, dehydrate them). Frequency will depend on amount of moisture in your environment. RECCOMMENDATION: Instructions state to put the beads in a glass over or microwave safe dish to recharge. This is a pain because it means pouring all of the beads out of the pouches on to the dish, then pouring them back into the pouches when done. Did I mention these suckers bounce!! Instead, experiment with pouches that can withstand the microwave. This way you can simply place all the pouches in the dish and microwave then. In my case it took 8 minutes on a 1200 watt oven. I use these pouches: B0BDQQ7SFG as well as the ones that come with the beads. BACK STORY I have a number of hobbies which include photography, drones, scuba and target shooting. I do not get to do these all the time due to cost and expense. As a result much of my equipment ends up stored in drawers and storage bins. I started noticing some plastic items getting sticky and rubber cracking. After much research I learned that it is highly recommended place silica bags in places where items will be stored to reduce moisute in the air which can/will lead to premature deterioration. After reading tons of reviews I decided to give these a try as they appeared to provide the best results for the cost. I have been using them for about two months now and have noticed a difference. I don't have equipment to test, but I tested them in a drawer with t-shirts that would always get a funk to them after time because I don't use them often. Since placing the silica bags in the drawer I have not gotten the funky smell. I was so pleased I purchased another jug and am placing silica pouches in all my drawers.

Le perline essiccanti in gel di silice wisedry si sono rivelate un acquisto eccellente per mantenere l'umidità sotto controllo in vari ambienti. Le ho utilizzate all'interno dell'AMS della mia stampante Bambulab e posso confermare che fanno un lavoro eccellente: mantengono l'umidità costante al 10%, garantendo condizioni ottimali per la conservazione dei filamenti. La caratteristica più apprezzabile è la loro riutilizzabilità: una volta sature, è sufficiente rigenerarle nel microonde o nel forno seguendo le istruzioni fornite, rendendole pronte per un nuovo utilizzo. Inoltre, l'indicatore di umidità arancione è estremamente utile, poiché cambia colore quando le perline hanno raggiunto la loro capacità massima di assorbimento, segnalando chiaramente il momento della rigenerazione. La dimensione delle perline (2-4 mm) le rende perfette per adattarsi a diversi utilizzi, e la loro capacità di assorbire fino al 30% del proprio peso in umidità le rende davvero efficaci. Per chi, come me, ha bisogno di proteggere i filamenti della stampante 3D dall'umidità, questo prodotto è una scelta eccellente! Consigliatissimo!

Works amazingly well in my 3d printer AMS, keeps filament perfectly dry. Great quality..!

These colour change to indicate refreshment needed. Good stuff.

Para quienes trabajan con impresoras 3D, la humedad es el enemigo número uno de los filamentos. Filamentos húmedos significan impresiones de mala calidad, atascos y mucha frustración. Por eso, cuando tuve la oportunidad de probar estas perlas de gel de sílice reutilizables Wisedry de 2,2 kg (aproximadamente 5 LBS) con indicador de color, las vi como una potencial salvación. ¡Y puedo decirles que son un verdadero "game changer" para cualquier entusiasta de la impresión 3D! Al abrir el paquete, la generosa cantidad de gel de sílice es lo que más impresiona. 2,2 kg es bastante, lo que me permitió utilizarlas para proteger varios rollos de filamento simultáneamente. Las perlas son de un tamaño uniforme y lo que más aprecio es el indicador de color. Inicialmente, son de un naranja vivo, indicando que están listas para absorber humedad. Esta funcionalidad es crucial para nosotros: cuando el color cambia a un verde oscuro, sabemos inmediatamente que han absorbido humedad y necesitan ser reactivadas. ¡No hay adivinanzas! El paquete trae 10 bolsas de organza con cordón, lo que es un excelente y muy práctico extra. Nos permite distribuir las perlas por varios recipientes herméticos donde guardamos los filamentos, o incluso dentro de las cajas donde vienen los rollos. Yo las uso directamente dentro de las bolsas Ziploc grandes donde guardo mis filamentos después de abiertos, y también en un contenedor más grande con varios rollos. La reutilización es el gran as de este producto. Cuando las perlas se ponen verdes, basta con extenderlas en una bandeja para hornear y colocarlas en el horno a baja temperatura (verifique las instrucciones para la temperatura exacta, pero típicamente rondan los 120°C) hasta que vuelvan a su color naranja original. Es un proceso simple y económico, que nos ahorra tener que comprar desecantes desechables continuamente y, lo más importante, estropear filamentos. La capacidad de absorción es notable. Noté una diferencia brutal en la calidad de mis impresiones desde que comencé a usar estas perlas. Se acabaron el "stringing" excesivo, la porosidad y esos crujidos irritantes que indican filamento húmedo. Mis impresiones son más limpias y consistentes.
