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

The blue desiccant silica gel beads work well to keep things dry. The very distinct color change is very helpful in determining when to re-dry the beads. I mainly use the blue desiccant in my AMS, and I've found I can go a long time before having to dry the beads. The bead size is perfect, with very few small particles that may slip through the desiccant screens or bags. I have completed three dry cycles on this batch already, and the beads are holding up nicely, so durability is not a concern. The bottle makes pouring easy, but I found that pairing it with a 3D-printed screw in a funnel improves the experience and minimizes spillage. There are concerns about the chemical used in the blue desiccant indicating silica gel beads, but I don't handle them often, and the particle size is large enough and heavy enough to not be an airborne concern.

Perfect used in my compressed air dryer. Saves time and money by absorbing water at the central output instead of at each tool instead of needing filters for each tools. Great value that outperforms the desiccant provided with the dryer.

Have ordered this multiple times. Wonderful product! I started using it with my 3D printer filament packed in mylar bags. Worked EXCELLENT. Brought the RH down to <10% within 24 hours and the print quality was dramatically improved, especially on TPU and some of the exotics. Then I tried it in a completely unrelated use case for final drying of basil, oregano, and thyme. Again, I had top notch results. In all this is a high quality product that can be reused many dozens of times and does exactly what it claims.

These silica gel beads change color clearly when saturated, making it easy to know when to recharge. The quart size provides plenty for multiple uses, and they work well for keeping storage areas dry.

Great to replace the old desiccant in my safe and in my filament dryer.

Works, filament is dry. Changes color when they need recharge. Can be dried out in oven. Nuff said.

Works fantastic, before I was using 60grams(20g each) 3 packets inside my filament enclosure and couldn't get below 20%RH after 24hrs, after putting in Dry & Dry, it dropped to 10%RH within 10min. Fantastic. You can see the ambient humidity was in the 40% range. Really works

Started using this in my AMS and the filament has been staying below 10% for weeks without having to run the heater. Good stuff.
