Are air purifiers a good option for keeping my apartment air cleaner?

I find the air in my apartment stale and I don't much like the smell. I don't think it's cooking smells and I don't smoke, I just think its the whole building (3 stories, 6 units and the hallway smells the same). I'm wondering if air purifiers really do work, thanks for any advice.
