I have a spacious wood shop that measures around 1800 square feet with 14-foot ceilings, which I converted from an old RV storage building. Although my Oneida dust collector works really well, I still notice dust lingering in the air during certain tasks, like using the tablesaw or routing. I'm looking for recommendations for effective air filters that can help keep the air clean in such a large space. Any suggestions? Thanks!

For a shop this size, it's actually better to use multiple air filters rather than just one. Given your space, which is roughly 25,000 cubic feet, you should aim for about 6 to 8 air changes per hour. I'd recommend using at least three air cleaners capable of outputting about 1000 CFM each to ensure good circulation.
You're looking at needing several high-capacity fans if you want to move enough air for that size of space—consider aiming for around 5000 CFM. Alternatively, it might be more effective to enhance your dust collection method at the source. For example, using a dust collection arm for your tablesaw and adding extra ports for your router table and bandsaw would help reduce airborne dust significantly.
