I've found just opening a window does the most to make a difference - in most European / US homes (even with propane / gas service) the "exhaust" just blows into the same room or a cabinet!
That said, I personally use the Breathe Airmonitor Plus [1] - I kept having issues with calibration with the temtop unit. Mostly decided on this one since it uses an NDIR sensor similar to my Aranet which I carry with me all the time.
