140 mm Magnetic Dust Filters — 4 Pack

These magnetic mesh filters fit any standard 140 mm fan mounting points on a PC case or power supply. The ultra-fine PVC mesh blocks dust while allowing air to pass, and the magnetic frame attaches directly to a metal chassis without tools or screws. Each filter measures 5.51 by 5.51 by 0.08 inches and weighs 0.02 pounds. The pack contains four washable, reusable filters for intake and exhaust positions.

Upgrade from Screw-On or Adhesive Filters

Magnetic mounting removes the need for screws, clips or sticky pads that can leave residue or vibrate over time. The jump is worth it when you want tool-free cleaning every couple of weeks — just pull the frame off, rinse with water and soap, and snap it back onto the steel panel. Do not bend the frame or put it in a washing machine; gentle hand washing keeps the mesh intact.

Limits of Magnetic Mounting on Steel Only

The filters only stay in place on ferromagnetic case panels or power-supply housings; aluminium, plastic or glass surfaces will not hold them. Mesh density is fixed at 1 mm hole size, so very fine particulate may still enter, and airflow restriction increases as dust builds up. Cleaning every few weeks maintains the balance between dust rejection and cooling performance.
