Most people use the AC Infinity in-line fans because they are quiet and pretty reliable. They are pricey compared to others though. I don’t have my Glowforge yet, but I do have the AC Infinity 6 inch fan and I can say it pretty quiet even on the highest speed. I can’t say much about fumes though as I have yet to test it with the Glowforge. I am curious about the filter thing though. I saw the AC Infinity version of it when I purchased my fan. I held off for now though. Just not sure how long it would last before the filter needs to be replaced.
