  Floor to ceiling in the ON ringing room is 13 feet. My perception is 
that ON's tower is breezier than Advent's even with the windows closed, 
but I could be wrong about that.

My envelope calculation says 315 m^3/hr can cycle the air 5 times an hour
in a space 15x15x10. 10’ is probably not the ceiling height in your
mother’s house, and also not in either tower, but it’s an understandable
amount.
