The 690NT is a gem of a product. Not only does this upgrade kit reduce sound by 50%, it also bolsters airflow by 20%. The white grille is set to match almost any decor your bathroom might currently have. If you have an older house with an older Nautilus N671 or N688, Broan 670, 671 688, 689 or Nutone 693, 695, 696N that has become noisy and inefficient, this is a hand in glove fit for you. This requires no wiring, no ductwork, just a simple 10 minute "plug and play" if you will.
