I’ve never once been in a property that had an exhaust fan sufficient. I’ve had the exhaust on full blast and the spike on the air quality sensor on another floor of the house is rapid and massive.

I suspect a sufficient ventilation would require something more like a lab fume hood that can pull a negative pressure on the area around the stove.

And from what I have seen, a good number of exhaust fans are straight up fake and just ventilate back in to the room rather than ducted outside.

There's a filter in it you're supposed to change regularly when they're in that configuration.

They contain a feels good filter to make you think something is happening. But to actually filter the pollution you'd need a activated carbon filter for the n02 and a hepa filter for the smoke. Which none of them contain and would clog rapidly.

It's massively easier to just not create the no2 by replacing gas with induction, and to vent the smoke outside rather than trying to trap it in a filter. I think the introduction of cheap consumer air quality sensors like from IKEA will start to make this problem a lot more visible to people.
