Most air quality measurement involves particulate matter, specifically PM 2.5. This is primarily wood smoke, car exhaust and a couple of other combustion-related. When the news talks about air quality, most commonly they are referring to PM 2.5. If you are looking for out-gassing (paints, carpets, furniture etc) you probably need to invest in formaldehyde and other gas sensors. In your case you ought to look at your furniture and electronics as they will produce the most out-gassing. This is different from the above particulate matter.
