I have a lot of cotton dust/lint - I find that there is more if I am cutting a lot of fabric and/or batting. And still a bit when I am sewing, especially once I get to large pieces. I have major dust allergies. I wear a face mask when cutting batting as it sends me into sneezing and coughing fits if I don't. I also use allergy meds and they help as well, but I still don't like inhaling it all. So if the fabric causes me to start sneezing or I get itchy eyes, etc. I'll limit my time and do other things in my quilt room to give my allergies a break or even leave the room for a while to let the 'dust' settle. I used two small air purifiers in my quilting room and even though they did pick up quite a bit of dust in their filters, they really do not have the strong air pull that I'd like, so I'm thinking of getting a better one, like my DH uses in his wood shop. You can find them most anywhere there is woodshop/workshop tools, like Wood Craft, Home Depot, etc.)
Just because your nose isn't full of 'dust/lint' doesn't mean that it isn't flying around the air. It's not like it is in clumps in the air. They are super fine particles. You would be surprised of just how much. Just look at a sun beam coming into a room through a window, it's full of dust particles.
DH runs the vacuum a lot in my quilting room. So that helps a lot as well. He is such a dear! He also dusts off the open shelves and light fixtures as well. He also cleans out my machine from the dust and lint and oils it after every project or two. Also when I change a bobbin, I take a larger, soft paint brush (that is used for oil or water paint) and use it to pick up the lint laying in the bobbin area. If I even get dust on my hands or skin, it gives me have contact dermatitis and itches until I wash up. That's why DH does all the dusting/vacuuming.
The best you can do is try to keep the dust/lint level cleaned up as much as possible. And if you have a place for an air purifier, especially part way, like shoulder level, between the floor and ceiling, that is were it works best. If it is on the floor, the dust has already fallen most of the way, and if it is too high, the majority of the dust might be missed in the air flow. So, mid-level is were it would pick up the most. At least in my experience.
