There’s some confusion, and I apologize.
It’s relatively easy to switch between either filter & a hose. You just turn off the filter, disconnect it, and connect the hose.
The thing that is hard was that someone wanted to connect their filter to their Glowforge, and then exhaust the filter outside. That is, send the clean filtered air outdoors. I don’t know why you’d want to do that, but it wouldn’t be particularly easy.
