It sounds, again assuming, that you just need to remove the coupler and then mount the dryer vent out the window.

Correct.

@fan-of-glowforge

couldn’t the filter be mounted in a window and connected to the Forge by a longer duct?

No, because…

@jacobturner

the filter doesn’t have a top cover.

@rpegg

keep in mind there is likely some sort of common control.

I’m not going to tell you it’s impossible, just that it’s nontrivial. Very nontrivial.
