Socks, stockings or tights made of silon also attract uses other than on our legs. Enthusiasts can use the material to make, for example, a dust filter for a PC fan. It’s effectiveness then depends on the thickness of the silon fibre. However, tests show that whatever type you use, it is a rather unsuitable solution. And it’s also difficult for robbers who don’t worry too much about the mask and just need a visit to the drugstore before the job.

I live in a very dusty home and decided to do exactly this after noticing my per fan nylon filters (SilverStone FF123) plus the front case filter (Corsair 4000D) were not enough to stop dust ingress so it’s really cool to see this tested, thanks!
For me the best way to make use of it was to cut a “leg” off, remove the “foot” and slide my cases intergrated front filter into the resulting tube of material. The material is thin enough the filter still fits no problem and I get two laters of material. I still see some dust on the nylon filters in front of the fans but very little dust passes into the system.
As shown in the tests it does reduce airflow but my 3x Arctic P12s at ~850 rpm still get enough air into the case. It is funny though I got an airflow focused case and I blocked off all holes except where there are fans giving it poor airflow! Seeing the dust build up I do consider my PC an air purifier now though
Thank you for sharing such valuable information. I’m sure it will be useful—and perhaps even inspiring—to some of our readers. 🙂
