I think it probably depends when your house is built? I would expect older houses to generally be a lot leakier? When I get home and have access to my laptop again, I think I can use the air quality measurements I took, which include CO2, to determine how leaky mine is as an example. I think the way to do this is look at how quickly CO2 levels fall off in an empty room?
While this is an old house, this particular room is essentially new construction: it was gutted in 2017 and redone with foam insulation and new windows, so it’s not surprising that it isn’t very leaky.

Looks like the room I’m testing in is only 0.45 ACH / 9 CFM: https://www.lesswrong.com/posts/eMDuTAA9uA7vFKeEA/ceiling-air-purifier?commentId=G6Addw3f7TpLwHCsD
