I will I look like a nerd wearing these things?

No, but you might look like a dork!

Will they keep out dust particles from clay in a pottery studio?

yes, when mowing the grass, doing laundry, to doing pottery, construction - these things have a lot of potential for effective applications to keep allergens out of your system. Just try it and see!

I get migraines from perfumes and other scents and fragrances. Would these filters block out any of these odors to reduce triggering a migraine?

No, I don't think they would. I use the filters most of the times when I am cleaning my house and when I use clorox for example, I still get some of its strong smell... But definitelly they help me a lot with my allergy to dust. Hope this helps.

What size are they. All the same or some different sizes?

These are the Large size. To get the smaller Medium size search for " first defense nasal screen medium " elsewhere on Amazon
