When the air starts to move more slowly because the cartridge is full, a beeping sound will notify you. You may be able to turn the dial clockwise to increase the fan speed and extend the cartridge life a little more. The beeping sound may not always occur when the cartridge needs to be changed; for example, if the carbon is used up but the airflow is still high.
When you detect smells during printing even when the Glowforge Air Filter dial is set to “Full”, it’s time to change the filter cartridge. Here’s how.
Turn off your Glowforge Air Filter.
The power switch is located on the back, next to the cord. Turn it off first, then unplug it from the wall.
Open your Glowforge Air Filter.
There are four latches holding the top of the Glowforge Air Filter in place. Lift the bottom of all four latches to release them. You do not need to remove the exhaust hose to change the filter cartridge.
Remove and dispose of the old filter cartridge.
Grab and lift the metal lip to remove the filter cartridge from the Glowforge Air Filter. Dispose of the used filter cartridge in the garbage.
Lift the filter cartridge out
Replace with a new filter cartridge.
You can purchase new filter cartridges from our shop. Unwrap the filter cartridge and inspect it for possible damage. Lower the new filter cartridge in the same way you removed the old one.
Latch the lid closed and recheck the exhaust hose.
Inspect each latch to ensure it is fully closed. Grab the lid handles and pull upward on the lid to ensure it does not come off. Finally, check the exhaust hose to ensure it has not become disconnected from either the lid or the back of your Glowforge.
That’s it - you’re ready to print!
