How can a shop determine which type of fume extractor to purchase?

If air pollution is an important issue for you and your employees, then choosing a ventless filtered fume extractor is a great option. The dust and VOCs are locked within the filters, ensuring that your company is not contributing to environmental air pollution. However, if you feel that air pollution is not an important issue for your company, then using a ventilation setup (industrial blower with ducting exhausting straight to the outdoors) may still be a viable solution.
