Replacing Filters

[rpegg]

I think the answer to your questions is in these two replies from dan.

It’s even more convoluted than that: it’s a liquid cooling system that circulates through the glass tube, then through an aluminum block, that has the exhaust air passing over it. To your question about air intake, it draws in from vents on the opposite side - it really needs to be in a place with ambient air that’s not too hot, or the heat exchanger doesn’t work efficiently.

@dan

The Glowforge has a connector to the air filter, which exhausts through many openings into the surrounding room. If you want to vent, don’t use the filter. If you use the filter, you can’t vent. The Glowforge plastics are final (the filter plastics are not) so that arrangement is not likely to change.
