## Long description

DEMCiflex 1104 is a bottom dust filter engineered for the Lian Li O11 Dynamic case. It attaches to the lower intake area and provides a physical barrier that reduces dust ingress to the power supply unit and lower-mounted cooling fans while preserving airflow. Finished in black, the filter uses a magnetic/clip-in mounting approach designed for easy removal and cleaning as part of routine case maintenance.
Advantages
The filter reduces particle accumulation on internal components without significantly restricting intake airflow, helping maintain cooling efficiency. Its removable mounting allows fast cleaning and reinstatement, and the black finish integrates unobtrusively with the case aesthetic. The design supports longer intervals between internal cleaning by capturing dust before it reaches the PSU and fan assemblies.
Suitable for
Users of the Lian Li O11 Dynamic case seeking bottom dust protection
Systems with lower intake fans and bottom-mounted power supplies
Environments with moderate dust where regular maintenance is performed
Key specifications

How to use
Align the filter with the lower intake opening of the Lian Li O11 Dynamic case and attach using the integrated magnets and clips until it is seated flush with the chassis. Inspect the filter periodically and remove it when visibly laden with dust.

Regular inspection and cleaning prolong the effectiveness of the filter and help keep internal components cleaner.
