excerpt: "The Lian Li TU150 lacks a bottom dust filter, leaving the intake fans exposed to dust. On Benjamin's recommendation, I got the DEMCiflex Dust Filter ST30 Double 120mm for US$11.32. It fits the case's two 120mm fans perfectly."

The Lian Li TU150 doesn’t come with any dust filter at the bottom. As the bottom fan is responsible for the intake of air, it will be dusty.

Benjamin recommended me to get the [DEMCiflex Dust Filter ST30 Double 120mm](https://www.demcifilter.com/demciflex-magnetic-dust-filter-for-alphacool-st30-double-120mm-dust-filter) from [Amazon](https://www.amazon.com/gp/product/B01IABY88K).

It retails for **US$11.32 (S$16)**, and shipping to Singapore is an additional US$4.62 (S$7).

Lian Li TU150 casing supports two 120mm fans, and hence this dust filter will fit nicely. Installation is easy since this dust filter is magnetic. You can stick it to the bottom of your case without the need for any screws or tools.

The mesh of this dust filter is made of medical-grade synthetic mesh. I am not sure what difference does it makes.
