Levoit Core 300S carbon filter insert

UPDATE: On request, uploaded a version with less carbon for better airflow I made an insert for the standard Levoit Core 300s Air-Purifier. The standard filter comes with very little amount of active-carbon, so we need more for an efficient filtration off all the particles our printers emmit. This insert is a compromise of filtration vs. still a good airflow. Feel free to test it and get a cheap upgrade for a way better filtration. Boost MeA boost is always apreciated.
