What's the difference between passive and active ventilation?

I will remove the laser from the filter when I am home and install the filter for use outside of the home

I searched and found this

Ideas for the hopper

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.

@Dan says what you want to do can’t be done.
