Fan Filter 120mm Alphacool 10297 — black, dust filter for 120 mm case and fan openings

The Alphacool Fan Filter 120mm (model 10297) is a black dust filter designed to be installed on standard 120 mm fan and case openings. It provides a physical barrier to airborne particles that can enter a computer chassis, helping to maintain airflow efficiency and reduce dust buildup on fans, radiators, heatsinks and other components. The filter is sized for common 120 mm mounts and intended for use in desktop PCs, servers and custom builds where dust control is a priority.

Advantages

The Alphacool 120mm filter reduces the amount of dust reaching internal components while preserving airflow through the fan or intake opening. Its black finish integrates visually with many cases and fan frames. By lowering dust accumulation, the filter can contribute to more stable long-term cooling performance and less frequent cleaning of radiators, fans and heat sinks.

Suitable for

• Desktop PC cases with standard 120 mm fan mounts
• Server chassis and rack units using 120 mm fans
• Custom builds and test benches where dust mitigation is required
• Cooling setups with 120 mm fans and radiators

When it may not be suitable

This filter is made for standard 120 mm openings and will not fit non-standard or proprietary fan sizes. If a system requires the absolute maximum airflow for extreme cooling scenarios, the added resistance of any dust filter may slightly reduce peak airflow. The filter does not replace regular maintenance; accumulated dust on the filter itself must be cleaned periodically to maintain optimal airflow.

Key specifications

• Form factor: designed for 120 mm fan and case openings
• Colour: black
• Primary function: dust filtration for airflow intakes and exhausts
• Compatibility: standard 120 mm mounting pattern and openings

How to use

Install the Alphacool 120mm fan filter by aligning it with the 120 mm fan or case opening so that the filter covers the intake or exhaust area. Secure the filter using the same screws or mounting method used for the fan or the dedicated filter retention points on the case. Periodically remove the filter and clean it with compressed air or a soft brush; wash and dry if the material permits and if heavier contamination is present. Reinstall once fully dry and check that mounting remains secure.

What to consider before purchase

• Confirm your case or fan uses standard 120 mm mounting dimensions.
• Assess whether a filter is acceptable for your cooling requirements; filters can introduce slight airflow resistance.
• Plan for routine cleaning to prevent blockage and preserve cooling performance.
• Ensure the black finish matches your case or aesthetic preferences.

Usage recommendations

For routine maintenance, inspect the filter every 1–3 months depending on the environment. In dusty or pet-friendly environments check and clean more frequently. Use gentle cleaning methods to avoid damaging the filter media and ensure it is completely dry before reinstalling.
