That makes sense during normal times, but when the air quality outside is hazardous, venting the air outside means it's pulling unfiltered air inside your house

That makes sense during normal times, but when the air quality outside is hazardous, venting the air outside means it's pulling unfiltered air inside your house. So use sparingly.
The last time I lived in a place with an unvented stovetop microwave fan, the previous owner never bothered to install the filters, so it was just recirculating unfiltered air.

Most likely you don't have perfect seals on all your windows, walls, doors, pipes, fans etc. Secondly, the air from cooking is generally very bad, especially if you're using nonstick surfaces or using much of anything with oil. It's probably better to trade it for smokey air outside.
