Westinghouse YX-Woanger-4433 fan accessory 1000 x 300 mm 1.2 mm mesh with 4 magnetic strips

1000 × 300 mm PVC dust filter

The Westinghouse YX-Woanger-4433 is a flexible PVC mesh sheet measuring 1000 by 300 millimetres with a 1.2 millimetre hole pattern. It targets PC builders who want to block dust while keeping airflow high on custom intake or exhaust openings. The sheet can be trimmed with scissors to fit any rectangular vent on a chassis, speaker cabinet or game console. Four adhesive-backed magnetic strips are included for tool-free mounting on ferrous surfaces.

Check case material and vent dimensions

Verify that the mounting surface is made of iron or steel so the magnetic strips will hold; aluminium, plastic or tempered glass will not work. Measure each vent you plan to cover and confirm the 1000 by 300 millimetre sheet is large enough to span the opening after cutting. Ensure there is clearance behind the mesh for the .39 millimetre thick magnetic strips so side panels still close flush. Clean the mounting area of dust and oil before applying the adhesive backing.

Replaces screw-on or adhesive-only filters

This kit replaces fixed screw-mount filters that require drilling and single-use adhesive meshes that leave residue. The magnetic attachment lets you remove the mesh in seconds for washing, then snap it back without tools. The upgrade is worth it when you clean filters monthly, when case panels lack screw holes near vents, or when you switch between open and filtered airflow for benchmarking. Builders who need a framed filter with a rigid border or who mount on non-magnetic panels should look elsewhere.
