Dust filter DEMCiflex DF0435 for Corsair Air 540 — 259×140 mm, black

DEMCiflex DF0435 is a replacement dust filter panel made to fit the front vent of the Corsair Air 540 case. The black rectangular filter measures 259×140 mm and is intended to reduce dust entering the case while allowing airflow to continue through intake or vent openings. This filter preserves interior cleanliness, supports component longevity by limiting dust accumulation, and restores or replaces a worn or missing factory panel.

Advantages

The DF0435 offers basic dust protection with a form factor matched to the Air 540 front vent. Its slim, low-profile design keeps airflow largely unobstructed while trapping dust particles before they settle inside the chassis. The black finish integrates with the case aesthetics and the crafted fit simplifies installation and replacement during routine maintenance.

Suitable for

• Replacement of a damaged or lost front vent filter on Corsair Air 540 cases
• Routine desktop maintenance to reduce internal dust buildup
