How to check if the Desiccant needs to be Replaced

When new, the desiccant will be a white powder. When the desiccant packs absorb moisture, they will gradually turn into a yellow paste. The desiccant needs to be changed when the entire pack is yellow because it loses the ability to keep the filament dry. It is also recommend to re-dry filament at this point. Please check if the desiccant needs to be replaced every 2 weeks. Learn more about the replacement of the desiccant on Bambu Lab Wiki.

• Please take 2 to 3 new desiccant packs, remove the plastic film from the desiccant, install it in the designated location for the AMS.
• Close the AMS cover to help keep your filament dry. Please ensure that the locking tabs on the AMS are closed to insulate the AMS from external air.
