What this pack contains

The Westinghouse 8541602773 accessory kit supplies two black PVC dust filters sized at 120 x 120mm. They are made for PC builders who want to block debris from entering a chassis through 120mm fan openings or speaker grilles. The pair weighs 0.02 pounds and comes in a single Art Deco style package.

Fitting the filters and common issues

Each filter sits over a 120mm fan frame and stays in place without tools, so installation takes seconds. The mesh density is rated at 89% dustproof, which restricts some airflow; builders chasing maximum static pressure may notice a drop. The PVC material can warp if forced into a misaligned mount, so check hole spacing before pressing it home.

Behaviour under continuous use

During sustained operation the filters collect dust on the surface rather than letting it reach the fan blades, keeping noise lower over time. The PVC construction resists deformation at normal case temperatures and can be rinsed clean when clogged. They do not address 80mm or 92mm openings, so systems with mixed fan sizes will still have unfiltered gaps.

Questions about this item

How can I tell the 120mm dust filters are working after I fit them?

You will see dust collecting on the black PVC mesh instead of inside the chassis, and fan noise should drop because airflow stays smooth.

What comes in the pack and is anything else needed?

The pack contains two 120 x 120mm PVC filters; no screws, frames or tools are included, so you only need a compatible 120mm fan opening.

Which filter size should I pick for my build?

Choose the 120mm version when your fan mount measures 120mm; 92mm and 80mm versions exist for smaller mounts.
