Anyone got one of these?

yep. draws stale air out of the kitchen and bathrooms and dumps it outside, pulls fresh air from the attic space.
it's been up there for 30+ years doing it's thing, i don't really think about it any more apart from pulling the core and washing the dust out every 2 or 3 years.

Pretty much every new house built to decent standards.

New houses are fairly air tight so they need a mechanical means to replace the air. Definitely a drain on resources though.
