Dust Filter for Fractal Design Define R6 (Bottom) — DEMCiflex 1087

The DEMCiflex bottom dust filter is designed for use with the Fractal Design Define R6 chassis to reduce dust ingress through the case bottom. Made to cover the intake area beneath the power supply and any lower vents, the filter traps dust and debris while maintaining case airflow. The removable design allows routine cleaning to help preserve component cleanliness and cooling efficiency.

Advantages

This bottom dust filter offers a fine mesh that captures small particles without significantly restricting airflow. Its custom-fit dimensions match the Fractal Design Define R6 bottom vent layout for straightforward installation and secure placement. The washable material supports repeated cleaning cycles, extending the interval between internal maintenance and helping to protect fans, PSU, and other lower-mounted components.

Suitable for

• Desktop PC builds using the Fractal Design Define R6 case
• Systems with bottom intake fans or lower-positioned power supplies
• Environments with moderate dust where regular filter cleaning is feasible

Key specifications

• Compatibility: Fractal Design Define R6 bottom vent layout
• Filter type: washable fine mesh dust filter
• Placement: bottom of the chassis, covering intake/PSU vents
• Material: flexible mesh suitable for washing and reinstallation
• Mounting: removable insert designed for easy removal and refit

How to use

Turn off the PC and disconnect power before accessing the case underside. Slide or place the filter into the designated bottom recess of the Define R6 so it sits flat and covers the intake area fully. Reconnect power and power on the system. For cleaning, remove the filter, rinse gently under running water or use compressed air to dislodge dust, allow to dry completely, and reinstall.

Recommendations

Inspect the filter every 1–3 months depending on the environment; wash when visible dust accumulation begins to reduce airflow. Avoid abrasive cleaning agents and ensure the filter is fully dry before reinstalling to prevent moisture contact with internal components.
