Compatible projector models

The Panasonic ET-RFE300 is a replacement air filter designed for the PT-EZ770, PT-EW730 and PT-EX800 series projectors. It maintains clean airflow through the optical engine to protect image quality. Installation is tool-free and matches the original equipment schedule.

Replacing the spent filter

This unit replaces the factory filter when it reaches the end of its service life. A fresh filter restores proper ventilation and prevents dust from settling on internal components. The change is worth it when the projector signals a filter warning or after the rated hours elapse.

Integration into the projector

The filter slides into the dedicated slot on the compatible models without additional hardware. It frees the cooling system from airflow restriction so the lamp and electronics run at stable temperatures. No extra clearance or cabling is required for the swap.

Questions about this item

Does the ET-RFE300 slide into the same filter slot as the original unit on my PT-EZ770?

Yes, the ET-RFE300 is the direct replacement filter unit for PT-EZ770, PT-EW730 and PT-EX800 series projectors and fits the existing filter compartment without modification.

What is the correct orientation when inserting the ET-RFE300 so the airflow arrow points the right way?

Insert the filter with the printed airflow arrow pointing toward the projector interior; the frame keyways only allow one orientation, so forcing it backwards is the common mistake.

How often should I plan to replace the ET-RFE300 filter in a typical office environment?

Panasonic recommends checking the filter every 300 hours and replacing it when the indicator appears or when dust buildup is visible, whichever comes first.
