Bathroom exhaust fan brings humid air into the house
Posted by Allison Bailes on July 20, 2018
Nope.  Today is not the first of April.  Nor is this one of those special April Fools' Day articles I write at random times.  This one's real.  A white noise generator has now been used in at least one home to reduce indoor humidity.  And no, this isn't an amazing scientific breakthrough either....
