Dust filter DEMCiflex DF0442 — 200×200 mm, for computer case, black or white

DEMCiflex DF0442 is a flat 200×200 mm dust filter made for computer cases and cooling intakes. Available in black or white, the filter prevents dust from entering the chassis while preserving airflow for 200 mm fans and vents or smaller openings. The slim panel design fits standard 200×200 mm cutouts and can be mounted on intake or exhaust ports to reduce internal dust accumulation and the frequency of manual cleaning.

Advantages

The DEMCiflex DF0442 combines a fine mesh with a low-profile frame to block dust particles without significantly restricting airflow. Its 200×200 mm dimensions make it compatible with large case fans and standard vents, and the two colour options help maintain a consistent aesthetic inside or outside the case. The flat construction enables easy installation and removal for cleaning, and the material is suitable for mounting on typical case materials; a non-ferrous mounting option should be chosen if the attachment surface is aluminium or acrylic.

Suitable for

• Filtering air intake for 200 mm fans in computer cases
• Protecting components from dust on vents and openings up to 200×200 mm
• Use on exhaust ports to limit dust redistribution inside the chassis
• Replacement or upgrade of existing 200 mm flat panel filters

Key specifications

• Overall dimensions: 200 × 200 mm
• Panel type: flat, low-profile filter panel
• Colour options: black or white
• Compatibility: fits 200 mm fans and vents, compatible with smaller openings
• Mounting: suitable for standard case openings; choose non-ferrous mounting if attaching to aluminium or acrylic surfaces

How to use

Position the DEMCiflex DF0442 over the 200×200 mm opening on the case so the mesh faces the airflow direction you want to filter. Secure the panel using the case’s mounting points or the appropriate fasteners for the chosen surface material. For non-ferrous surfaces such as aluminium or acrylic, use the non-ferrous mounting option. Remove the filter periodically and rinse or gently vacuum the mesh to restore airflow; allow the filter to dry completely before reinstalling.

Usage recommendations

Inspect the filter every 1–3 months depending on environmental dust levels, and clean sooner in dusty or high-traffic environments. When cleaning, avoid harsh chemicals or abrasive brushes that could damage the mesh. If airflow restriction increases after cleaning, check for trapped debris along the frame or mounting area and ensure the filter is fully dry and correctly seated.
