Dust Filter 120mm square DEMCiflex DF0688 white/white

DEMCiflex 120mm square dust filter DF0688 in white/white is designed to provide basic dust protection for desktop PC cases and ventilation intakes that accept 120 mm square fan-sized filters. The filter combines a fine mesh medium with a snap-in plastic frame to trap dust particles while allowing steady airflow, helping to reduce dust buildup on internal components and cooling surfaces. The neutral white finish suits a range of case interiors and external intakes where a low-profile, replaceable filter is required.

Advantages

This dust filter offers a simple, tool-free installation thanks to its snap-in frame that fits standard 120 mm square openings. The fine mesh captures common household dust and lint without significantly restricting airflow, supporting effective cooling of fans and radiators. As a replaceable element, it enables regular maintenance: users can remove, clean or swap the filter to maintain airflow and prolong component life. The white/white color provides a discreet appearance in light-coloured systems and front-panel intakes.

Suitable for

• Desktop PC cases with 120 mm square fan openings
• Front and side ventilation intakes on computer enclosures
• External fan mounts and small electronics requiring dust filtration

How to use

Install the DEMCiflex dust filter by aligning the square frame with the 120 mm fan opening and pressing it into place until the snap-in tabs engage. For intake filters, install on the exterior side of the case or behind the front panel depending on your case design. To clean, remove the filter by disengaging the snap tabs, rinse the mesh gently with water and allow it to dry completely before reinstallation; replace the filter if the mesh is damaged or permanently clogged. Regular inspection and cleaning help maintain cooling performance.

Recommendations

Check the filter during routine PC maintenance and clean every 1–3 months depending on environment; in dusty or pet-friendly environments clean more frequently. Ensure the filter is fully dry before reinstalling to avoid moisture near electronic components.
