Any cooking will decrease it.

I have several air sensors and even using the oven will change the air quality from "green" to "yellow".

Even just frying veggies with a bit of oil on an electric cooktop sends my air quality into "red". Overheating oil sends it into the "purple" level which is "unhealthy".

I would love to know which air sensors you use.

Dyson Cool+Hot Air Purifier (built-in sensors), Atmotube and Awair.

Generally true. Particles generally reach your lungs, and the cooked food goes through chemical reaction and so on, so you ideally don't want that.

Probably high-heat cooking of anything (e.g. pan trying) will pollute quite a bit even on an electric range.

I use the stove vent every time I cook for this reason.
