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.

If only externally-extracting fans were a codified standard for stove hoods in the way that bathroom fans and dryer vents are.

It's actually just wild - my last apt in Manhattan was built in 2018 and had a gas range. The "exhaust fan" just vented back into the kitchen and the only "exhaust" per se was a vent in the bathroom that "sucked" all the way to the roof with negative pressure.

If I ran my stove for more than 15 min my carbon monoxide / fire alarm would go off.

Wow! Do building codes allow that? I thought natural gas stoves had to be vented to outside.
