Compatible Projector Models

This genuine Sony air filter fits the VPL-GH10 and the VPL-HW10, HW15, HW20, HW30 and HW40 home-cinema projectors. It is a direct replacement part for owners of those specific units who need to maintain proper airflow and protect the optical engine from dust ingress.

Maintenance Role and Daily Impact

The filter stops dust from settling on internal lenses and the lamp assembly. A clogged filter reduces fan efficiency, causing heat to build up and shortening the life of both the projector and the lamp. Replacing it when you change the lamp keeps cooling performance at its intended level.

Pre-Order Checks

Verify that your projector model appears in the supported list above before ordering. If your unit shows a filter-warning icon or message on screen, replace the filter immediately. Otherwise, remove the existing filter and inspect it visually; any visible dust buildup means it should be swapped out.
