What are examples of local exhaust systems in homes?

Local exhaust systems in homes are designed to remove contaminants, excess moisture, and odors from specific areas, thereby improving air quality and reducing humidity levels. Examples of local exhaust systems include those found in kitchens, bathrooms, laundry rooms, and clothes dryer systems.

In kitchens, exhaust hoods above stoves help capture smoke, odors, and cooking vapors before they can disperse throughout the home. Bathrooms typically feature exhaust fans to eliminate moisture generated during showers and baths, which can lead to mold growth if not properly ventilated. Laundry rooms may also have dedicated ventilation systems to expel humidity and lint produced during washing and drying clothes.

While living room and hallway fans may provide some air circulation, they do not serve the specific function of local exhaust systems. Similarly, attic and basement exhausts are more related to overall house ventilation rather than the targeted removal of contaminants from localized areas. Whole-house air circulators provide general airflow and do not effectively address the specific needs of localized areas like kitchens or bathrooms. Thus, the systems found in kitchens, bathrooms, laundry areas, and attached to dryers are the most fitting examples of local exhaust systems in homes.
