or worse none

I've never seen a stove without a vent hood above it...?

I have. I've also seen vent hoods that don't actually dump to the outside, they just pass through a small filter and dump the air right back inside...

Which is okay if it's a carbon filter to remove smells and nox you're going to change every year.

But many are just mesh grease filters and are never changed.

I've seen a bunch in NYC, especially in older apartment studios.
