My wife wanted to go to Niagara, but for the cost of the trip I could buy a real working waterfall and install it in my home. Not only would we get the sound of rushing water but it would help condition the air to a comfortable humidity level and help filter out dust, dander and other allergens. If you are bold, you could order a really, really, really big custom one and perhaps even CHARGE admission to tourists. As part of a remodel or addition it would not be hard to install one and it is like a piece of art on your wall that functions as a piece of HVAC equipment.
This is not your grandfather’s backlit rushing waterfall beer sign that your wife makes you keep in the garage. It is a tried-and-true working waterfall.
