Genuine Hitachi MU07791 Air Filter Cartridge

This genuine Hitachi MU07791 air filter cartridge is designed for CP-X4022WN and CP-X5022WN projectors as well as compatible Dukane and Imagepro models. It serves as a direct replacement part for routine maintenance cycles.

Simple cartridge swap protects optical components

The cartridge format allows tool-free removal and insertion during scheduled service or lamp changes. Regular replacement stops dust from settling on internal optics and maintains the cooling airflow that the projector relies on.

Fixed maintenance interval limits flexibility

Manufacturers recommend cleaning every three months and swapping the filter at each lamp change, so the part must be kept on hand for planned downtime. Projectors without a filter warning icon require manual inspection to avoid overheating risk.
