Calcium Chloride Desiccant – High Capacity Moisture Absorber for 3D Printer Filament Storage These calcium chloride desiccant packs provide strong moisture control for filament storage across all 3D printer brands – Bambu Lab, Creality, Prusa, Anycubic, Elegoo, and others. Each order includes eight individual packs, each containing calcium chloride salt with high moisture absorption capacity. Calcium chloride absorbs several times its own weight in moisture, offering stronger water capture than standard silica gel desiccants. The beads are white or beige when dry and gradually darken as moisture accumulates, providing visual feedback on absorption status. These packs work effectively inside any airtight environment: filament dry boxes, vacuum storage bags, AMS units (including AMS, AMS Pro, AMS HT), Creality CPAP, or simple tool cabinets. Suitable for PLA, PETG, ABS, ASA, nylon, TPU, and other moisture-sensitive filaments. Long-lasting performance in high humidity environments (60%–90% RH) reduces the need for frequent replacement. Calcium chloride desiccant is designed for single use. When fully saturated, dispose and replace with fresh packs. This disposable format ensures consistent protection without the need for oven or microwave reactivation. In the box: 8 packs of calcium chloride desiccant, single-use disposable format.
