Disposable cartridges also use silica gel and can be regenerated or disposed of. To regenerate the cartridge can be gently heated overnight at 50 degrees celsius, or by removing the silica beads and placing it on glass or a porcelain dish. The beads are then heated to 150 degrees celsius for 1-2 hours.
