Magnetic 140mm Dust Filters

This two-pack of magnetic PVC mesh filters fits 140mm fan mounts measuring 287mm by 147mm. The 0.5mm hole diameter blocks fine dust while maintaining airflow for PC cases, power supplies or speaker grilles. Installation requires no screws because the magnetic frame holds the filter securely in place.

PVC Mesh With Strong Magnetic Frame

Each filter uses a 0.45mm thick PVC mesh stretched over a metal frame that snaps onto steel chassis panels. The wider magnetic strip resists vibration so the filter stays aligned during transport or when the case is moved. When the mesh collects dust it can be rinsed or vacuumed and reinstalled in seconds.

Low Restriction Airflow And Silent Operation

The fine 0.5mm pores add minimal static pressure drop so case fans run at their normal speed without audible turbulence. No power draw or moving parts are introduced, keeping system thermals and noise unchanged while reducing internal cleaning frequency.

Questions about this item

What hole size does the 287mm magnetic filter mesh use to block dust?

The PVC mesh has 0.5mm diameter holes, which are smaller than standard filters to stop more dust from entering the case or power supply.

What are the exact outer dimensions of each filter in the 2-pack?

Each magnetic frame measures 287mm by 147mm, with a PVC mesh thickness of 0.45mm, designed to cover 140mm fan mounting areas on cases or speakers.

How do you install the magnetic frames so they do not fall off?

Align the wider magnetic frame directly onto the steel fan mount or grille; the strong magnets hold it without screws, but the surface must be ferrous metal for a secure fit.
