Dust filter DEMCiflex for Lian Li TU150 Mini ITX – GPU dust filter C1397

DEMCiflex dust filter designed for Lian Li TU150 Mini ITX cases protects the GPU area and nearby internal components from airborne dust. Model C1397 is a replacement/upgrade filter that fits the TU150 Mini ITX GPU venting zone, helping maintain cleaner airflow paths and reducing the need for frequent maintenance in compact desktop builds. The filter is intended for use in small form-factor systems where space is limited but dust control and component longevity are priorities.

Advantages

The filter provides a fine barrier against dust while preserving airflow characteristics required by GPU cooling. Its form factor matches the GPU vent area of the TU150 Mini ITX case, enabling a secure fit and straightforward installation. By capturing dust before it settles on heatsinks, fans and PCB surfaces, the filter contributes to more stable thermal performance and reduced cleaning intervals. The material choice balances filtration efficiency and low airflow resistance to avoid negatively affecting GPU temperatures.

Suitable for

• Small form-factor desktop builds based on Lian Li TU150 Mini ITX case
• Users aiming to reduce internal dust accumulation around the GPU
• Systems where lower maintenance frequency is desired without compromising airflow
• PC enthusiasts replacing a worn or damaged GPU-area filter

Key specifications

• Compatible shape and dimensions for the GPU vent area of the Lian Li TU150 Mini ITX case
• Thin, flexible filter media designed for minimal airflow restriction
• Reusable/cleanable material suitable for periodic maintenance
• Durable edge or frame to maintain position over the vent

How to use

Turn off and unplug the PC before accessing the GPU area. Remove the side panels of the TU150 Mini ITX case to reach the GPU vent zone. Carefully remove the existing filter or clean the mounting area if no filter is present. Position the DEMCiflex filter so it aligns with the GPU vent openings and secure it in place according to the case’s mounting method. Reassemble the case panels and power the system on. Periodically inspect the filter and clean it using compressed air or by rinsing with water and allowing it to dry completely before reinstalling.

Recommendations

For best results, check the filter every 1–3 months depending on ambient dust levels and operating hours. Clean reusable filters gently to avoid damaging the media, and replace the filter if tears or permanent deformation occur. Ensure the filter is fully dry before reinstalling to prevent moisture contact with electronics.
