Overview Bambu Activated Carbon Air Filter Melt extrusion printers will generate VOCs while printing because the heating temperature of ABS, PC, PA and other materials is relatively high, resulting in more VOCs. Materials such as PLA with lower melting points produce much fewer VOCs during printing. These VOCs are absorbed by our activated carbon air filter. Compatibility X1* Series and P1S Not compatible with X1E User Guide The X1-Carbon comes with a carbon filter which is used for filtering the air from the enclosure before it is expelled outside. Here's how you can replace it: Remove the plastic cover Gently pull on the carbon filter to remove it Install the new carbon filter Attach the plastic cover Product Specifications Function: Used to absorb volatile organic compounds Working Life: 1440 hours (60 days) cumulative printing time Materials: Paper box, activated carbon Package size: 109*55*33 mm Package weight: 110g Colour: Black
