120mm

100 percent brand new dust filters for computer and electronics fans, made of durable PVC material and designed to keep components cleaner, quieter, and longer lasting. Key benefits - Reduces dust buildup inside cases and on components, helping to maintain cooling performance and prevent overheating. - Fine mesh provides efficient dust filtration while allowing good airflow, so cooling is not compromised. - Washable and reusable design makes maintenance simple and cost effective. - Adds slight acoustic dampening to help reduce fan noise and vibrational sound from fan grills. - Tough, low-flex material holds its shape for easy mounting and long service life. Product features and specifications - Material: PVC. - Color: Black. - Size: approximately 12 x 12 cm (4.7 x 4.7 inches). - Finish: fine, dust-proof mesh with small holes for effective filtration. - Construction: low flexibility for stable attachment to fan front or rear, and high toughness for durability. - Maintenance: washable for repeated use. Compatibility and performance - Designed to fit standard 120 mm case fans and other 12 x 12 cm fan locations where a square filter is required. - Suitable for use on fan intakes and exhausts, speaker grilles, and small vents on a variety of electronic products. - Helps keep PC internals and components clean, reduces noise transmission from fans, and contributes to extended component life by lowering dust accumulation. Typical use scenarios - Desktop gaming or workstation PC: attach to the front intake fan to reduce dust entering the case and help maintain cooler operating temperatures. - Home audio equipment: place over speaker vents or amplifier fans to prevent dust buildup on drivers and internal electronics. - Small electronics and appliances: cover vents on routers, set top boxes, and other devices to reduce dust entry while preserving airflow. Installation and care - Filters are easy to mount on the front or back of fans because of their stable, low-flex design. - Rinse with water to clean and allow to air dry completely before reinstalling. - Allow for slight dimensional variation due to manual measurement when selecting mounting method. Package contents - 10 x dust filters. Please allow slight size variance due to manual measurement.
