Absolutely. My high heat cooking produces a good deal of particulate emissions and always sets off the kitchen air filter, but it's all from the food in the pan. It has nothing to do with the burner technology.

I know this because it doesn't happen when I'm boiling.

If you’re boiling you have worse problems than particular emissions

Sorry, couldn’t resist

The odour you smell is unburnt gas (to make gas leaks less dangerous). Burning gas produces carbon monoxide (among other things), which has no odour.

You made me look it up. Methane has no smell, so they add an odorant. Usually these contain sulfur, so there will be some amount of sulfur dioxide in the combustion products. Sulfur levels as limited to 70ppb, and are typically around 7ppb. This compares to a natural atmospheric level of sulfur dioxide at 1ppb. So unless you are breathing something like 10% combustion product the contribution is negligible.

The rest of the odor molecule is hyrdrogen, carbon, and oxygen, so likely goes to water and carbon dioxide or monoxide.

The problem with this thinking is you're referring to a constant factor; you'd be cooking the same foods either way, searing all the same.

These effects are cumulative, it's not some threshold you cross where the other negatives are no longer relevant because you do something far worse.

It's like people who rationalize eating a pint of ice cream before bed because they had mcdonalds and a beer for lunch already. The appropriate action would be to skip dinner and dessert altogether, but they're doing the opposite due to such wrongheaded thinking.

You should really be thinking "hey, my cooking produces a lot of particulates, I wonder if I can clean up the process elsewhere at least"

I think your analogy is missing the scale. In this case, I think it's likely that the equivalent scale would be worrying about eating a tic tac, when lunchtime is beer and burgers.

How about not cooking animal products, i save more emmissions that way than spending $2k on an appliance that will be obsolete or irreparable in 5~6 years.

As with ad-hominem, this isn't actually a fallacy - it's just declared as such by people who don't understand Bayesian reasoning. Using informed judgement helps us separate fact from fiction.
