Quiet Spot Ventilators

Mechanical ventilation should be a key component of any strategy for ensuring good indoor air quality in buildings. In homes, one of the least costly options with mechanical ventilation is to use spot ventilators in areas that generate high levels of moisture or pollutants, especially bathrooms and kitchens.

Bathroom fans and range hoods are almost always installed—indeed they are required by most building codes—but there is one big problem. Most of these fans are so noisy that homeowners do not use them.
