Portable filters also work. I have a office shed I work out of and the difference is noticeable when I have a little $70 filter inside running.
One of the best economy filters you can make is to put a good hvac filter on the back of a box fan. Box fans move a lot of air. Make sure tape it / seal it to the back or a lot of the air will pass through any openings. I had a filter that was a little too small for the fan, so I took the cardboard sides off and stretched it over the fan. That also made it easier to tape it up with a good seal.
Happy breathing.
