Compatible Projector Models

This air filter fits a wide range of Hitachi, Maxell and Dukane projectors. Compatible series include CP-EW, CP-EX, CP-WX and CP-X models with matching part numbers. It replaces the original filter in each listed unit.

Maintenance Role and Installation

The filter blocks dust from reaching internal optical components and maintains proper airflow for cooling. A clogged filter reduces fan effectiveness and can shorten projector and lamp life. Replacement is straightforward and often done during lamp changes.

Replacement Intervals and Limits

Manufacturers recommend cleaning every three months and replacing the filter when the lamp is changed. Some projectors display a warning icon when the filter needs attention. Without a warning, visual inspection for any buildup is the only guide.
