A proper range hood (so one that vents externally as opposed to in a cabinet…) is pretty much an essential. Both for cooking in general and for lighting gas on fire a few feet from your face for extended periods of time.

Been a minute but I want to say the Technology Connections video where he put an air quality sensor next to a gas stove also talked about opening a window?

But my not a doctor and not that kind of scientist statement: What you need is air circulation. So fans and open windows.
