Ensure that you use laser-compatible materials, like Proofgrade hardwood, plywood, and
acrylic. Different materials will fill the filter cartridge at different rates. MDF and Proofgrade
Draftboard are not recommended, as they will cause the filter cartridge to fill quickly.
When your print is done, leave your Glowforge Air Filter running.
Running air through your Glowforge Air Filter will prolong the life of the cartridge. For best
results, leave it running one minute for each minute that you print. For example, when you finish
two 30-minute prints, leave it running for an hour after they finish.
Turn off your Glowforge Air Filter.
When you’re done, use the switch next to the power cable to turn off the Glowforge Air
Filter.
Materials will have an odor when they’re removed. If you prefer, you can reduce this odor by
leaving the materials in your Glowforge longer while the Glowforge Air Filter is running.
Cleaning, Service & Moving
Unplug your Glowforge Air Filter off before cleaning, moving, changing the filter cartridge, or doing
any other cleaning or maintenance.
Change Filter Cartridge
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 knob 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 and unplug 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 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.
