ET-RFL310 Panasonic Filter Replacements

The Panasonic ET-RFL310 Air Filter replacement prevents dust from building up on the optical elements of your projector unit. It plays a critical role in preventing dust accumulation. If the air filter becomes clogged it will result in higher operating temperatures because of reduced air flow. This could ultimately reduce the lamp life of your projector. If you are replacing your Panasonic Projector Lamp, it is also a good idea to replace your ET-RFL310 filter. Manufacturers suggest replacing the filter when changing the lamp to ensure optimal performance. Read our Blog article on why regularly replacing your air filter will increase the life of your Panasonic Lamp and Projector.

Please rate your purchasing experience with Pureland Supply and the overall quality of this lamp star

Whew, finally got that new projector lamp installed in the simulator and the image is crystal clear again thanks to PurelandSupply's fast shipping. Their team was super helpful figuring out exactly which bulb, the ET-RFL310, I needed for our Panasonic projector, and they even walked me through a couple of troubleshooting steps. Now the students can get back to virtually hitting the links – huge relief!
