Air filter DEMCiflex 0974 for PC case, black, compatible with Lian Li PC-011

DEMCiflex 0974 is a black air filter designed for PC cases, compatible with the Lian Li PC-011 series. It provides fine dust filtration for intake and exhaust vents to protect internal components and maintain steady airflow. The filter is shaped to fit the front vent, side vents and the top panel vent of the Lian Li PC-011 case; to cover all vents of that case, order four filters. The product helps reduce internal dust buildup and lowers the frequency of deep cleaning for desktops and custom builds.

Advantages

The filter uses a fine mesh material that captures dust particles while allowing adequate airflow for cooling systems. Its form factor matches the Lian Li PC-011 vent openings for straightforward installation and reliable coverage. The black finish provides a discreet appearance that integrates with most case interiors and exteriors. The washable design allows repeated use, supporting routine maintenance without frequent replacement.

Suitable for

• Dust protection for Lian Li PC-011 series desktop computers
• Custom PC builds requiring front, side or top vent filtration
• Systems in dusty environments where reduced maintenance is desired
• Users who prefer washable, reusable case filters

Key specifications

• Color: black
• Form factor: panel-style filter sized for Lian Li PC-011 vents (front, side, top)
• Material: fine dust mesh suitable for airflow and particle capture

How to use

Turn off the computer and disconnect power before installing or removing the filter. Align the filter with the case vent and press into place following the case’s mounting points or magnetic strips if present. For full coverage of the Lian Li PC-011, install one filter on each front, side and top vent—four units in total. To clean, remove the filter, rinse gently under running water, allow it to dry completely and reinstall.

Recommendations

Inspect filters monthly in dusty environments and clean when visible dust accumulation appears; under normal home use, cleaning every 2–3 months is typically sufficient. Replace the filter if the mesh becomes damaged or deformed. If you need to cover all vents on a Lian Li PC-011 case, purchase four identical filters for complete protection.
