Dust Filter for Fractal Design Define R6 (Rear) by DEMCiflex – MPN 1086

DEMCiflex rear dust filter designed for the Fractal Design Define R6 chassis provides targeted particle protection for the rear intake/exhaust area. The filter helps limit dust ingress into the case, supporting cleaner internal components and more consistent airflow over time. It is intended as a replacement or spare part to maintain system hygiene and reduce the need for internal cleaning.

Advantages

The filter is made to match the rear mounting area of the Define R6, offering an exact fit that does not interfere with fan operation or cable routing. Its fine mesh captures common household and PC dust while remaining thin enough to preserve airflow performance. Installation and removal are straightforward, which makes periodic cleaning quick and convenient. Using a dedicated rear dust filter contributes to longer component life and more stable cooling behavior.

Suitable for

• Replacing a missing or damaged rear dust filter on a Fractal Design Define R6
• Adding a spare filter to simplify regular maintenance
• Maintaining cleaner CPU and GPU cooling by reducing dust accumulation
• Systems located in dust-prone environments such as workshops or home offices

Key specifications

• Compatible area: rear intake/exhaust section of the Fractal Design Define R6 chassis
• Material: fine dust mesh designed for particle capture while allowing airflow
• Form factor: low-profile panel tailored for rear mounting without obstructing fans
• Maintenance: washable and reusable by gentle cleaning

How to use

Turn off and unplug the PC before installing or removing the filter. Access the rear panel of the Define R6 and remove any obstructing cables or fasteners as required. Align the DEMCiflex filter with the rear opening and attach it according to the chassis’ mounting points; ensure it sits flush and does not contact the fan blades. For cleaning, gently remove the filter and rinse under low-pressure water or use compressed air to dislodge dust, then allow it to dry completely before reinstalling.

Recommendations

Check the filter monthly if the system is used in a dusty environment; otherwise inspect every 2–3 months. Clean the filter before heavy dust buildup to maintain optimal airflow and cooling. Avoid using harsh chemicals or high-pressure washing that could deform the mesh.
