Dust filter DEMCiflex DF0015 for computer cases, round 109 mm (black)

DEMCiflex DF0015 is a round 109 mm (109 × 109 mm footprint) dust filter in black mesh, designed to reduce dust ingress into computer cases and cooling fans. The filter is compatible with standard 92 mm fan and vent mounting patterns by using a 10.9 cm diameter specification and provides a fine mesh barrier that helps maintain internal airflow while trapping dust particles before they reach components.

Advantages

The DEMCiflex round dust filter provides a balance between airflow preservation and dust capture with a low-profile design that installs over fan intakes and chassis vents. Its black mesh integrates unobtrusively into most system interiors and front panels, and the construction is intended for easy cleaning and reinstallation. The filter adapts to common 92 mm mounting layouts and can be applied to both intake and exhaust locations where a round filter is suitable.

Suitable for

• Desktop PC cases with 92 mm fans or vents
• Home theater PCs (HTPCs) and small form-factor builds
• Custom cooling solutions and replacement fan filters
• Vent openings where a round 109 mm filter footprint is required

Key specifications

• Shape: round
• Outer footprint: 109 × 109 mm
• Compatible mounting pattern: fits standard 92 mm fan/vent layouts
• Mesh color: black
• Primary function: dust filtration for chassis and fan intakes

How to use

Position the DEMCiflex DF0015 over the fan or vent opening so the mesh covers the intake area, aligning it with the standard 92 mm mounting holes if applicable. Secure the filter using the existing fan screws or appropriate fasteners for the case panel. For surfaces made of non-ferrous materials such as aluminium or acrylic, choose the matching non-ferrous mounting option if required. Remove the filter periodically and wash or blow out accumulated dust before reinstalling to maintain optimal airflow.

Usage recommendations

For effective long-term protection, check the filter every 1–3 months depending on environment and dust levels. Clean gently with compressed air or rinse under running water and allow to dry fully before refitting. Use on intake locations to reduce dust build-up inside the chassis and avoid obstructing the mesh to preserve cooling performance.
