## Long description

DEMCiflex dust filter set for Lian Li PC-O11 Air in black/black is a pair of replaceable mesh filters engineered to protect intake and ventilated areas of the PC-O11 Air chassis. Designed to fit the case's fan vents and front/side intake openings, the set helps reduce dust accumulation on internal components while preserving airflow characteristics. The black finish matches the case aesthetics and offers a low-profile solution for routine maintenance or upgrades.
Advantages
The filter set provides fine particulate screening without significantly restricting airflow, helping to extend the time between interior cleanings and to preserve cooling performance. Its tailored fit for the PC-O11 Air ensures secure placement and easy removal for cleaning or replacement. Constructed for straightforward installation, the filters are lightweight and designed to blend with the case finish while providing visible dust protection for fans, radiators, and other intake areas.
Suitable for
 System builders assembling a Lian Li PC-O11 Air chassis
 Users replacing worn or missing intake filters
 Those seeking to reduce dust buildup on fans, radiators, and internal components
 Maintenance routines that require easy-to-clean or replaceable filtration
Key specifications
 Compatibility: designed for Lian Li PC-O11 Air case ventilation and intake openings
 Color: black mesh with black frame
 Material: fine mesh filtration media with rigid frame for mounting
 Coverage: intended for primary intake and fan vent locations on the chassis
 Weight: lightweight, optimized to avoid additional strain on mounting points
How to use
Turn off and unplug the system before attempting installation. Remove the panel or bezel that provides access to the targeted intake or fan vents on the Lian Li PC-O11 Air. Position the DEMCiflex filter so that the frame aligns with the case mounting points and press gently until it seats securely. To clean, remove the filter and use compressed air or a soft brush to dislodge dust; for more thorough cleaning rinse the mesh with lukewarm water and allow it to dry completely before reinstalling. Replace the filters if the mesh shows permanent damage or reduced airflow after cleaning.
Usage recommendations
 Check filters monthly in dusty environments and clean every 1–3 months under normal conditions. When reinstalling, ensure the filter is mounted flush to prevent gaps that could allow unfiltered air to enter the chassis.
