I live in an area that has harmful amounts on PM2.5 during the winter(80ug/m3+, double that a few days of the year). You'll need an air filter, but not just any other one - it has to be oversized for the living space and spin up at a low threshold - air filters commonly only actually start when the measurements indicate more than 25ug/m3. Also nice if it has an ionizer - my experience is that it generally increases effectiveness even though that's not exactly its purpose. Aside from that it's important to seal all windows properly. Even a large filter won't do much against draft.

> Also nice if it has an ionizer I'd be concerned that the ionizers generate trace ozone. Am I wrong about this?

  They do - no way around it which I would know of. I only experienced a whiff of ozone when I returned home after two weeks, with the device on all this time. Personally I only ever feel the irritating effect of elevated PM levels, so I keep the ionizer on. I definitely cough much less during a cold now, having the purifier, than before purchasing it.
