Dust filter DEMCiflex 0320 for PC cases, 142×287 mm, black/grey

DEMCiflex 0320 is a dust filter designed for PC cases, measuring 142 × 287 mm. The two-tone black and grey frame combines with a fine mesh to reduce the ingress of dust and larger particles through intake or exhaust openings. The filter is intended as a replacement or an upgrade for standard case ventilation filters and helps maintain internal airflow performance while reducing dust accumulation on components.

Advantages

The DEMCiflex 0320 offers a durable frame and a fine filtration layer that capture common household dust without significantly restricting airflow. Its flat, rectangular design and standardized dimensions make it compatible with many mid-tower and small-form-factor cases. The filter’s neutral black/grey appearance integrates unobtrusively into most chassis designs while supporting regular maintenance and easy cleaning.

Suitable for

• Replacement or upgrade of PC case intake and exhaust filters
• Maintaining cleaner interiors in desktop gaming and office systems
• Protecting fans, heatsinks and other components from dust buildup
• Systems where a low-profile, easy-to-clean filter is preferred

Key specifications

• Colour: black and grey frame

How to use

Fit the DEMCiflex 0320 into a compatible 142 × 287 mm opening on the PC case, aligning the frame with the vent or fan housing. If the case uses magnetic or snap-in retention, press the filter into position until it sits securely; if an adhesive or bracket is required, follow the case manufacturer’s mounting method. Periodically remove the filter for inspection and cleaning to preserve airflow and filtration performance.

Usage recommendations

Clean the filter every 1–3 months depending on environment: use compressed air blowout or gentle vacuuming on the mesh side and, if needed, hand-wash with mild detergent and allow to dry completely before reinstallation. Avoid placing the filter where it will be exposed to liquids or oils, and verify clearance inside the case to prevent contact with spinning fan blades.
