Westinghouse 120mm Fan Dust Filters

This pair of 120mm dust filters fits standard computer case fans and speaker grilles. Each filter measures 120 by 120 millimetres or 4.72 by 4.72 inches. They are made from durable black PVC for long-lasting performance.

Two filters cover intake and exhaust

The pack includes two identical filters so both intake and exhaust positions can be protected at once. The three-in-one design blocks dust, stops cables from contacting spinning blades and shields fingers from accidental contact. Both functions work without extra parts.

Mounting holes at 105mm and 150mm

Installation requires a fan frame with 105mm parallel hole spacing and 150mm diagonal hole spacing. Builders whose fans use a different hole pattern cannot mount these filters securely. No other dimensions or hole patterns are supported.

Questions about this item

How often should the 120mm dust filters be cleaned to maintain airflow?

Clean the filters whenever visible dust builds up on the PVC mesh; regular cleaning keeps airflow steady and protects the fan bearings.

What mounting pattern limits which 120mm fans these covers fit?

The covers require 105mm parallel hole spacing and 150mm diagonal hole spacing, matching standard 120mm fan frames.

Does the black PVC material affect noise or heat when the fan runs continuously?

The thin PVC mesh adds minimal airflow resistance, so fan noise and case temperatures stay virtually unchanged during all-day operation.
