Dust filter DEMCiflex DF0507 for Cooler Master 690 III, black, pack of 5

DEMCiflex DF0507 is a set of five black dust filters made to fit the ventilation openings of the Cooler Master 690 III computer case. The pack is intended to reduce dust ingress into the chassis, protecting fans, heatsinks and other internal components while helping maintain consistent airflow and cooling performance over time. Filters are supplied as a kit of five pieces to cover multiple intake or exhaust openings and are designed for straightforward replacement during routine maintenance.

How to use

Recommendations

Inspect filters every 1–3 months depending on environment; clean washable filters by rinsing with lukewarm water and allowing them to dry completely before reinstallation. Replace filters when mesh shows signs of wear, damage or irreversible clogging. Use the 5-piece pack to place fresh filters on frequently used intake points and keep spares for scheduled maintenance.
