- What this is - Set of 5 magnetic-frame dust filters for PC cases, designed to reduce dust buildup on internal components. - Key benefits - Keeps components cleaner: traps dust before it reaches fans, power supplies, and vents, reducing maintenance and extending component life. - Maintains airflow: the dust net cover with holes blocks dust while still allowing proper air circulation so cooling performance is not compromised. - Fast installation and removal: magnetic frames attach to metal case panels for tool-free mounting and easy cleaning. - Important attributes - Quantity: 5 pieces per set. - Size range: 8–14 cm, suitable for common case fan locations and vents. - Fit detail: the 8 cm option provides a precise fit for compatible components. - Design: magnetic frame with dust net cover featuring airflow-friendly holes. - Compatibility - Works with PC cases that have metal surfaces where the magnetic frame can attach. - Suitable for protecting case cooling fans, fan intakes, vents and power supply intakes that match the 8–14 cm size range. - Performance and care - Effectively reduces dust accumulation while preserving airflow. - Remove filters easily for cleaning to restore peak airflow and filtration. - Practical use scenarios - Gaming or high-performance desktops: place over intake fans to prevent dust buildup from affecting temperature and fan longevity. - Home offices with pets or dust sources: protect the power supply and case vents to reduce cleaning frequency. - Small servers or workstations in dusty environments: use the magnetic filters on intake vents to lower internal dust levels and maintenance needs. - Why choose these filters - Simple magnetic mounting, proven dust-blocking design, and a set of five sizes to cover multiple intake locations, including a precise 8 cm option for smaller fan or vent openings.
