If you already have the Advanced Filtration System for the Original Enclosure or have the Alveo3d Hepa Filter with the blower, you can now install it to the Prusa Core One.
Please note that while there is a fan header on the Core One extension board, according to their firmware, you can't utilize that header yet. I'm sure this will be enabled once the firmware gets updated, but in the meantime, you can use the power supply that was used for the enclosure to use the fan.
EDIT 4/2/2025
As of today, Prusa released the 6.3.1 FW for the Core One, which enables the use of the FAN3 header on the buddy extension board. This FAN3 header is for the Advanced Filtration System, which can be purchased from Prusa, or you can use this model to retrofit the MK4/3S enclosure filter.
Hardware Needed
Four (4) M3x8mm Socket Cap Screws to mount the printed bracket
Instructions
- Remove the back panel and PSU cover.
- Route the blower cable through the grommet above the buddy extension board and then connect the blower fan to the FAN3 header on the buddy extension board.

- Mount the blower to the bracket using the original hardware from the Advanced Filtration System.
- Mount the fan + bracket onto the Core One using the 4 M3x8mm bolts.
- On the Core One screen go to Settings > Hardware > Chamber Filtration > Enable Adv Filtration
