Magnetic 140mm Fan Filter 4-Pack

This four-pack supplies 140mm magnetic dust filters that attach directly to any steel chassis or power-supply intake. The PVC mesh uses a 1mm hole pattern to stop dust while letting air pass. Each filter measures 5.51 by 5.51 by .08 inches and weighs .02 pounds.

Sustained Airflow and Dust Capture

The fine mesh maintains its open area after weeks of dust buildup, so case pressure stays stable during long gaming or rendering sessions. Because the frame is magnetic, the filter can be lifted off in seconds for a quick rinse without breaking the seal or misaligning the mount.

Replaces Screw-On or Adhesive Filters

Builders who currently use screw-mounted grilles or sticky-backed mesh gain tool-free removal and a tighter seal on metal panels. The upgrade is worth it when filter cleaning is frequent or when case access is limited by tight cable routing.

Questions about this item

Will the 1mm PVC mesh restrict airflow or raise temperatures when the PC runs all day?

The ultra-fine mesh is designed to reject dust without sacrificing heat dissipation, so temperatures stay stable even during continuous operation.

Does my case need screw holes or a metal frame for these magnetic filters to attach?

The magnetic frame clings directly to any steel chassis around a 140mm fan opening; no screw holes or extra brackets are required.

Can I use these on an older case that has 140mm mounts but thinner steel panels?

Yes, they fit any standard 140mm fan size and the magnets hold through typical case panel thicknesses.
