DIY PC Case Dust Filter 400x300mm, 1.2mm hole 🖥️

This set of magnetic dust filters for PC cases helps keep internal components cleaner with a simple DIY approach, reducing maintenance time and improving airflow over time. The pack includes four PVC mesh panels sized 400 x 300 mm plus magnetic strips, a practical option for custom builds or replacing worn filters.

Key Points

The filters attach with magnetic strips so you can fit them to steel cases without drilling or screws, making installation quick and tool-free. The PVC mesh has 1.2 mm holes which block larger dust particles while allowing airflow, and the material is flexible and washable for easy reuse. Included are 16 magnetic strips of 400 mm which let you arrange the panels in different configurations depending on case layout and fan positions. One nuance to consider is that magnetic attachment requires a ferrous surface on the case, so they will not adhere to aluminium or plastic panels without an additional metal surface.

Technical Specifications

• Name: YSSHUI 4 Pack 400 x 300 mm magnetic dust filter

• Size: 400 x 300 mm per panel
• Hole diameter: 1.2 mm
• Material: PVC mesh
• Magnets included: 16 strips, 400 mm each

Usage Recommendations

Place a filter over intake areas such as front, top or bottom vents to reduce dust ingress and lower the frequency of internal cleaning. For best results wash the PVC mesh under running water when clogged and allow it to dry before reattaching, the mesh is designed to be cleaned rather than replaced frequently. If you move components between cases that are non-ferrous, carry a set of small steel strips or use adhesive magnetic bases to maintain magnetic attachment.

Advantages

This solution offers simple, reversible protection without modifying the case, which suits people who like to experiment with different layouts or who swap components regularly. It helps lengthen the time between full cleanings and makes routine maintenance less time consuming. The lightweight panels do not add significant weight and can be trimmed or layered for bespoke coverage. 😊
