EIKI 63340047 Replacement Filter ( Sponge )

Replacement sponge-type air filter for compatible EIKI projectors, including the EK-103X. The open-cell sponge element sits in the projector's intake path and captures dust before it reaches the lamp, optics, and cooling system. Swapping the filter on a regular schedule maintains airflow, prevents thermal shutdowns, and preserves image brightness, and is recommended whenever the element becomes discolored or clogged.
