Using a sensitive meter I measured the levels of PM 2.5 in my open-plan room. Measurements were taken every half hour from 11am to 8pm. The stove was lit at pm.
11.16
007
11.26
037
Experiment: I lit one match and let it burn almost to finger. I stood 2 metres from the meter.
11.48
007
Levels returned to 007 about ten minutes later.
13.10
107
Wife gently cooked an omelette (did not burn it).
13.21 | 13.53 | 14.23
90 > 55 > 37
It took one hour and 13 minutes for the PM2.5 levels (caused by the wife cooking an omelette ;-) to drop from 107 to 37
14.53 | 15.25
026 > 019
And another hour to drop from 37 to 19
17.12 | 17.18
011 > 016
Prior to lighting reading is 011.
17.22 | 17.24
016 > 017
Why did lighting a match not cause a raise as it did in the morning? Because I lit the match just inside the stove door and the draw of the chimney sucked away any smoke or smell from the match.
17.29
016
A couple of minutes after opening the door, prodding the logs to rearrange, and adding a new log.
17.39
014
18.01
010
18.16
008
Rest of evening settles around 008.
