Abstract: A vent hood is configured to receive air from a cooking environment, the vent hood including a filter. A post-filter air quality sensor is configured to provide an air quality signal indicative of sensed air quality parameters of air after exiting the filter. A vent hood controller is configured to indicate an alert that the filter requires servicing, based on a comparison of the sensed air quality parameters to baseline air quality parameters indicating a lack of filter efficiency.

Abstract: A vent system for a dryer, may include an exhaust air conduit configured to provide an airstream to a dryer; a sensor within the conduit and configured to measure the airstream; and a controller configured to receive sensor data from the sensor and determine an airflow. A method for detecting a variation in airflow through a vent of a dryer may include receiving sensor data from at least one sensor in an air conduit of a clothes dryer; determining an estimated airflow based on the sensor data; comparing the estimated airflow to a predetermined expected airflow; and adjusting the estimated airflow in response to the estimated airflow not being within a predefined margin of the predetermined expected airflow.
