I've put one in my new house. They are typically a whole home solution with the main part of the draw coming from the "wettest" part of the house. Bathrooms, fishrooms, etc. I have mine drawing from within my fish tank canopy and from my fishroom. It then deposits the fresh air about 10ft from my display in the center of the house. I have one with a variable fan that can run from 60cfm all the way to 150cfm. The higher the speed, the more likely that it's noisy. I ran extra large piping through the house to avoid the noise.
