So is there a smell that our brain blocks out or ignores because it is always there? Or have we evolved to have lungs that don’t have a notable odor?

This is why you can taste/smell saline when it’s injected. Trace amounts of dissolved things (which taste like plastic and metal) in the saline are able to pass through the alveoli in the lungs and evaporate into your breath.
Oddly, I think it’s a similar thing with my ADHD meds because about an hour or two after taking them my breath smells/tastes weird.
