Dust filter kit DEMCiflex DAN Case A4 SFX, black, 269.6×149.7 mm, 2 pcs

DEMCiflex DAN Case A4 SFX External Dust Filter Kit contains two black external dust filters sized 269.6 × 149.7 mm designed to attach to the ventilation openings of DAN A4 SFX computer cases. These external filters reduce dust ingress into compact SFX builds, help protect fans, heatsinks and other internal components, and simplify cleaning and maintenance by trapping particles before they enter the chassis.

Advantages

The filters provide a fine mesh barrier that decreases dust accumulation inside the case without altering airflow layout. Their external mounting makes installation and removal quick and tool-free in most setups, enabling regular cleaning without opening the chassis. The slim profile preserves clearance for case panels and cables while offering durable, washable material suitable for repeated use.

Suitable for

• Owners of DAN A4 SFX computer cases requiring external dust protection
• Compact desktop and small-form-factor SFX system builds
• Users who prefer easy-to-remove washable filters for regular maintenance
• Systems where preserving internal airflow and component access is important

How to use

Align each filter with the outside of the corresponding ventilation opening on the DAN A4 SFX case and attach according to the case's external fit method. Ensure the filter sits flush against the vent so air passes through the mesh. Remove the filters periodically and rinse or brush off accumulated dust; allow them to dry fully before reattaching. Follow the case manufacturer's guidance for any clip or magnet attachment points when securing the filter.

Recommendations

Inspect and clean the filters every 2–8 weeks depending on ambient dust levels. Use a soft brush or low-pressure compressed air to remove loose particles and lukewarm water with mild detergent for deeper cleaning. Do not dry with heat sources or iron the mesh; reattach only when completely dry.
