Air filter DEMCiflex 0976 for Lian-Li PC-011, black, 200×110 mm

DEMCiflex 0976 is a black replacement air filter designed to fit Lian-Li PC-011 series desktop cases, specifically for the rear panel vent of the PC-011 Air. With external dimensions of 200 × 110 mm and supplied as a single piece, the filter offers straightforward dust protection for intake or exhaust openings where a compatible magnetic or fitted filter is required. The thin, low-profile design preserves airflow while capturing dust and larger particles before they enter the chassis.

Advantages

The filter combines a slim form factor with a magnetic or fitted attachment solution to ensure secure placement on the case vent without significantly restricting airflow. Its black finish integrates visually with dark case interiors and exteriors. By preventing dust buildup on internal components, the filter helps maintain stable cooling performance and can reduce the frequency of internal cleaning.

Suitable for

• Lian-Li PC-011 series PC-011 Air rear panel vent protection
• Desktop systems where a 200 × 110 mm fitted or magnetic filter is required
• Builders seeking simple dust control for intake or exhaust openings

Key specifications

• Color: black
• External dimensions: 200 × 110 mm
• Quantity: 1 piece per pack
• Attachment type: magnetic or fitted (compatible with magnetic/fitted mounting points)
• Function: dust filtration for PC chassis vents

How to use

Align the filter with the rear panel vent of the Lian-Li PC-011 case so that the magnetic or fitted edge contacts the case frame. If the case uses magnetic attachment points, allow the filter to seat and adhere to the metal surface; if using fitted slots, slide or press the filter into the vent frame until secure. Periodically inspect the filter surface and remove accumulated dust by gently vacuuming or rinsing with water if the filter material permits; allow full drying before reinstallation to avoid moisture inside the case.

Usage recommendations

For consistent cooling performance, check the filter every 1–3 months depending on environment and dust levels, and clean or replace it when visible clogging reduces airflow. Avoid using abrasive cleaning methods and ensure the filter is fully dry before placing it back on the case.
