"Dry & Dry" [7.5 LBS] Premium Orange Indicating Silica Gel Desiccant Beads(Industry Standard 3-5 mm) - Rechargeable(1 Gallon)

This stuff sucks... Moisture away! I've been using this stuff to keep my 3D printing filament dry and it works wonderfully. I've also successfully recharged it in the oven twice now (Florida has high humidity). It's very easy to tell when it's time to recharge because the color indication is *very* apparent. It's also not hazardous waste like the blue color-indicating silica gel! Orange-to-green color-indicating silica gel uses Methyl Violet which is mostly harmless (but don't let your dog eat it!) whereas the blue-to-pink color-indicating silica gel is *seriously toxic hazardous waste*: It uses chromium chloride. WARNING: If you spill it IT MAKES A HUGE MESS. Ugh. I've experienced a small spill and a *large* spill now and let me tell you: It's like dropping a million little ball bearings on the floor. They *go every which way* and will sneak into every nook and cranny in your garage/house. They also *hurt* when you accidentally step on them barefoot in the middle of the night to get a drink. They're also hard to see because the green color is semi-transparent which is the perfect camouflage for an object on the floor of any house or garage. If you *do* spill just vacuum them up. Yeah, they'll get dirty as all heck--they'll even *attract* dirt and make the floor extra clean--but silica gel still works fine when dirty. Also, if you're thinking, "I'll just wash them off" DO NOT DO THAT! If you pour water over this kind of silica gel IT CAN EXPLODE. Not in a dangerous sort of way, no. In a MESSY sort of way. So after doing a great job vacuuming it all up you'll have to repeat the process all over again except this time you'll have to vacuum the walls as well!

Fabulous! Works great!

I purchased the 5.5 lb container TWICE ... once in June and once in December for my 3d Printer Filament storage containers. I have had to recharge half the June purchase only once so far and the recharge in the oven worked perfectly. The product works GREAT and I have no complaints. In my smaller single spool containers the beads are still working with no recharge needed so far. It was my larger test containers (that leaked a lot of air) that needed the beads recharged, but now that I have better containers, the beads just last and last without any recharged needed. It is amazing how long they are lasting (probably also due to the fact that I have about 9-10 ounces of beads in each container.) My ambient room humidity is about 50-55% (I live in Florida), and the storage containers are all easily below 20% humidity. The seller is also great and responsive. I had a very slight concern on my second purchase and messaged them thru Amazon. The seller was EXTREMELY responsive and gave me answers to the questions that I had. They also went out of their way to ensure that I was a satisfied customer, which I am. I would not hesitate to purchase from Dry & Dry again and would STRONGLY RECOMMEND them and this product.

Incredible value and a great product but I'm pretty unhappy the product doesn't come in a tub or some other storage solution. it came in a ziplock bag with a sealed outer foil bag. Sad but ease of use and packaging are huge for this. I don't need it all over my floor because a bag tipped, etc. It would be a 5+ star affair had this not been the case. It works great, changes colors when done (tested in my car after a car wash). I'm currently using it in a small gun safe, in individually sealed containers with fly-tying materials (natural skins and hairs), fly-tying hooks, a plastic sealed ammo can, in my fly fishing reel box (just in case the backing and line haven't dried out all the way, put them in the container without their neoprene socks on first) and I put a few in an emergency supply bag along with a few sealed fire starting packs as well. I have simply placed a moderate amount in full size letter envelopes and sealed the envelope seams with painters tape. Good to go.

It works great! Wow, you don't realize how much you get until you receive it!

It's color indicating silica. It keeps my stuff dry and I can easily see when it needs recharged. I found that if I spread the beads across a couple of cookie sheets it recharges much quicker than if it's stacked deep in a pan. The price is very competitive especially as you move to larger quantities if you have the need for bulk amounts. Leaving the review after using this for a couple of years because I decided to get some more!

Fantastic product!

This is great! I've used two jugs between the additional desiccant containers I printed to fill all the empty space in the Bambu Labs AMS and in the bottom of the filament storage dry box I made with a silicone sealed plastic storage bin from Target and a couple wire drying racks.
