Gelid Mesh Magnet 140 Fan Dust Filter for 120mm fans 3pcs GEL-MESH-MAGNET-140-3

Gelid's Mesh Magnet filters are designed to prevent dust from entering your PC. Dust not only worsens aesthetics but reduces cooling performance and can also accumulate a certain amount of electrical capacity and conductivity which goes on to affect reliability and lifespan of your computer.
Featuring tiny fiber and airflow optimised PVC mesh with a dense 17 pores per inch; the Mesh Magnet ensures dust filtering and allows up to 90% airflow free pass. They are durable; washable; reusable and compatible to all standard fans and vents.
The Mesh Magnet can be applied to the air intake or outlet of the metallic PC chassis; PSU cabinet; HTPC or any other device with fans installed. Fits just in seconds thanks to the magnetic design!
If your PC chassis is non-metallic; the magnetic frame can be removed and the filter can be fitted to the chassis vents with the pre-applied magnetic tape.
