wisedry [ 5 LBS ] Silica Gel Beads Reusable Color Indicating Rechargeable Desiccant Bulk with 10 Pcs Organza Drawstring Bags

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.

Got these to keep my printer filament dry and it does the job well. No complaints. It takes a bit to recharge, but still great product,

This Wisedry Desiccant product is really only useful for small storage situations, such as drawers or storage containers. The desiccant absorbs moisture quickly and turns from orange to green in only a few days. It’s inconvenient to keep recharging the product so often. I have a 65% percent humid environment, which makes it a bit more challenging. However, the fabric/organza bags are far more convenient to recharge (several minutes) in a microwave than desiccant sold in metal containers, which can take hours to recharge in the oven. This makes it much more convenient when you have many desiccant bags in use throughout the home. The other issue has to do with recharging the pellets in the microwave. The desiccant pellets cannot withstand over-heating. If I heated one organza bag pack over 5 minutes (just to get it back to the orange color) some of the pellets started to deform in shape. Maybe this product will work better for those with low humidity environments. If you use a lot of storage containers like I do, I found that it’s better to use an electric dehumidifier in the room housing the storage containers. Pros: 1) Convenient 2) Easy to use 3) Microwaveable 4) Desiccant is effective at drying Cons: 1) Drying effect does not last long in humid environments 2) Pellets can deform from recharging too long (in microwave)

I’ve been using this product for a variety of cleaning projects, from tackling tough grease in the kitchen to freshening up surfaces around the house. It’s been a game-changer! What really stood out to me is how effective it is at absorbing moisture quickly—it’s perfect for spills or any mess that needs to be cleaned up fast. It’s versatile, reliable, and has made my cleaning routine so much easier. Highly recommend!

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.

I have previously used the 50 gram wisedry silica packets and they served their purpose. I wanted to be able to create larger packets of silica and this was the best, most cost effective way to do it. I like the color changing beads that tell me when they are no longer working. The silica beads are easy to recharge and reuse.

Good stuff! The included mesh bags are perfect. I have filled them and put them in various storage containers, file cabinets, cars, RV and closets. So far everything is staying dry, no more musty odors.

Product arrived but had no included bags with it, which was frustrating. I now have to wait (and pay) for bags to arrive.
