Dust filter DEMCiflex for Lian Li O11 Dynamic Rear 1105, magnetic rear panel fit

DEMCiflex Dust Filter 1105 is a magnetic rear-panel filter designed specifically to fit the Lian Li O11 Dynamic rear opening. It delivers fine dust filtration to reduce dust accumulation on internal components while maintaining unrestricted airflow. The filter is shaped and magnetized to align with the O11 Dynamic rear panel, allowing quick installation and removal for periodic cleaning without tools.

Advantages

The filter provides effective particle capture thanks to its fine mesh, which helps prolong the lifespan of fans, radiators and other internal hardware. Magnetic attachment ensures a secure fit while enabling tool-free access for maintenance. The lightweight and low-profile design preserves case airflow dynamics and does not interfere with mounting or cable routing at the rear panel.

Suitable for

• Dust reduction in Lian Li O11 Dynamic desktop PC builds
• Protecting rear-mounted fans and radiators from particle ingress
• Users who prefer easy-to-remove magnetic filters for regular cleaning

Key specifications

• Compatibility: rear panel dimensions of Lian Li O11 Dynamic
• Attachment: magnetic edge for tool-free mounting
• Material: fine mesh filtration fabric with magnetic frame
• Function: particulate/dust filtration while allowing airflow
• Design: low-profile, lightweight construction

How to use

Align the magnetic edge of the DEMCiflex filter with the rear opening of the Lian Li O11 Dynamic case and let the magnets seat it in place. Remove the filter by pulling at a corner or designated tab and wash or clean the mesh as needed using compressed air or a gentle rinse, then allow it to dry completely before reinstalling. Regular inspection and cleaning will maintain airflow and filtration performance.

Recommendations

For best results, clean the filter every few weeks or more frequently in dusty environments. Avoid harsh chemicals when washing the mesh and ensure the filter is fully dry before reattaching to prevent moisture contact with internal components.
