> Yes, if you have a colossal jet-powered A+ grade hood with a fan that vents outside.

Quite an exaggeration. Even cheap vent hoods (assuming vented to outside, of course) can move a lot of air.

You don’t have to 100% mitigate the problem to make an impact.

The author’s core analysis may be valid, but the rush to dismiss any mitigating factors feels like a significant bias showing through.

Depends. Newer houses are built almost air tight, you have to either open a window or have a makeup air system installed to pump air into the house while the vent fan is running. Unless you do that, the poor fan is working very hard trying to basically create a vacuum in your house.

Everyone just needs HEPA filtration in their home. It shouldn’t be “do this because it’s good and not that because it’s bad” but knowing about, measuring, and mitigating fine particles in your life.

Switching away from gas is one mitigation, but it doesn’t handle everything.

HEPA filters don't filter NO2.
