Yes, I wear a mask and I recommend everyone do so.
Years ago I found that I am allergic to and sensitive to the VOC's released by hardwoods while scrolling and planing them. I have to wear something to stop the VOC's, so just a particulate mask will not suffice, for me, your milage may vary.
I use two different masks depending on what I'm doing; the first, a true respirator with replaceable filter types, there is a VOC cartridge with a P95 prefilter, and a P100 cartridge. The second is a "nuisance" mask that has a charcoal filter layer that I use when I'm out and about and there is "stuff" in the air (windstorms and wildfire smoke are two). this maks is quite effective and doesn't scare people.

For the shop air (my scroll saw is inside my house) I use a box fan and air filters that fit (20 x 20"), this fans runs 24/7 and continually cleans the air.
