YIMATEECO 120mm Nylon 80 Mesh Magnetic Dust Filter 2pcs

120 mm Magnetic Dust Filter for PC Cases

This pair of 120 mm nylon mesh filters mounts on any steel chassis using weak magnetic strips, so no screws or adhesive are required. The 80 mesh construction yields a 0.2 mm aperture that blocks pet hair and fine dust from entering coolers, power supplies or router vents. Each filter measures 12 cm by 12 cm by 0.16 cm and is sold as a two-piece set in black.

Washable Mesh and Low Airflow Restriction

The nylon material can be wiped clean or rinsed gently without bending, and the supplier suggests cleaning or replacement every three months. Because the mesh aperture is only 0.2 mm, airflow resistance remains low while still stopping particles that would otherwise settle on fan blades or heat-sink fins. No moving parts are added, so acoustic output is unchanged from the bare fan.

80 Mesh Nylon with Magnetic Frame

The defining specification is the 80 mesh nylon screen paired with a flexible magnetic PVC frame. This combination fits standard 120 mm mounting holes and works with screw or sticker mounts as a fallback. Buyers who need a finer aperture than 0.2 mm or a non-magnetic mounting method should look elsewhere.
