The replacement frequency for the air filter in your Panasonic ET-RFF200C unit depends on how you use it. For specific instructions on maintaining your air filter unit, always consult the operating instructions that came with your projector. If you operate the projector without the main filter unit attached, the filter indicator will flash red, and a message will display on the projected image for about 30 seconds. To resolve this, power off the projector, attach the main filter unit, and then restart the projector to prevent potential issues.
