What customers say
This magnetic dust filter kit earns high praise for its exceptional custom fit and remarkable ease of use specifically for the Lian-Li O11-Air case.

The magnetic attachment system is a standout feature, simplifying both installation and routine cleaning to be completely tool free.

Know before you buy
This specific kit is precision-engineered for the Lian-Li PC-O11XL-Air. Because the Air model features different ventilation layouts and panel dimensions compared to the standard Dynamic, this kit will not fit other O11 variants correctly.
No tools are required. The filters use a magnetic frame that snaps directly onto the metal surfaces of your case. If you have a non-metallic surface, the kit includes adhesive magnetic strips to ensure a secure fit.
While any filter will cause a minor reduction in airflow, DEMCiflex uses a medical-grade mesh designed to balance high-efficiency dust capture with maximum air permeability. Keeping your components dust-free actually helps maintain better thermal performance over time compared to a clogged, unfiltered system.
The kit includes 8 individual filters designed to cover every intake and exhaust vent on the Lian-Li PC-O11XL-Air. This ensures complete protection for your entire system.
Cleaning is simple because the filters are magnetic. Just peel them off the case, wipe the dust away with a cloth or use a vacuum, and snap them back into place. The black mesh makes it easy to see exactly when they need attention.
