Whatever you decide to use it must be designed so the return air passes through hepa filtration. This can be a bank of flat filters in a wall if the unit is in a "doghouse", or using cylinders. The dust that is of concern remains airborn almost forever- ultra fine particles that get into the lungs and are very difficult/impossible for your system to clear. Not to mention many aspects of bowyerism uses synthetics like epoxy, glass and phenolics.
One problem with being casual about taking care with your respitory system is the damage won't always appear until later in life. See those guys wearing oxygen? That was my uncle too. A life in woolen mills-he hit 65 and his system just collapsed. The Dr said thats typical. The lungs just couldn't handle what he had already put into them anymore, even though it had been years since he'd left that occupation.
The worst systems are the bag types directly returning air into the room when only being filtered by the bags. The dust that is put back into the space is the smallest and most dangerous size. I'm a woodworker, and believe me, once you set up a good system using and maintaining it is essentially hassle free. And your shop is much nicer to work in.
I consider a good dust collection system to be as important in my line of work as any of my machines.
I would think building bows, with all the sanding and other operations that make dust, to be on par with what I do in that regard.
Try to collect it as close to source as you can.
