Dust Filter for Lian Li TU150 Mini ITX PSU by DEMCiflex (MPN C1396)

DEMCiflex removable dust filter designed for the PSU intake area of the Lian Li TU150 Mini ITX chassis. The filter fits the compact power supply opening and provides a physical barrier against dust and debris that can accumulate inside a small form factor case. It is intended for periodic removal, cleaning, and replacement to help maintain steady airflow and cooling performance for the power supply and surrounding components.

Advantages

The filter reduces dust ingress to the PSU intake without obstructing normal airflow, helping to preserve cooling efficiency in a mini ITX build. Its removable design simplifies cleaning and routine maintenance, allowing users to restore filtration performance quickly. The slim profile and form-fit are made to integrate with the chassis layout so the filter does not interfere with cable routing or PSU installation.

Suitable for

• Mini ITX desktop systems using the Lian Li TU150 chassis
• PC builds where dust control for the power supply is required
• Environments with moderate dust where regular maintenance is feasible
• Users who perform periodic cleaning to maintain cooling performance

Key specifications

• Form factor: removable, thin-profile dust filter designed for PSU intake
• Material: fine mesh filtration media with a supporting frame
• Compatibility: designed to match the intake opening geometry of the specified mini ITX chassis
• Maintenance: washable or brush-cleanable surface for repeated use
• Function: reduces dust accumulation while permitting normal airflow for cooling

How to use

Power down the system and unplug it before attempting removal. Access the PSU intake area according to the chassis instructions, then gently remove the dust filter by disengaging any clips or sliding it free from its mounting position. Clean the filter by brushing or rinsing with water and allow it to dry completely before reinstallation. Reinsert the filter into its original position, ensuring it sits flush and secure, then reassemble the chassis and restore power.

Recommendations

Inspect the filter every one to three months depending on ambient dust levels. Clean more frequently in dusty environments to maintain optimal airflow and cooling. Replace the filter if the mesh shows tearing, permanent deformation, or if cleaning no longer restores airflow.
