Gas stoves fill the air in your home with particulate matter (pm), which has been found to increase cancer risk in the long term.
So next time you buy a stove, consider choosing an induction stove.
Btw, gas stoves being better or faster than induction is a myth. They have certain specific advantages, but they are actually slower.

Very few residences have proper ventilation. In the US, a microwave above the stove is common. Microwave often do have a fan function, but the vast majority don’t vent outdoors. I doubt that running air through a very thin filter will do much good.
I hate this. I think it should be illegal. Or make a building code that there has to be a real extractor hood above the stove in all cases.
