AUTOMATIC SENSING VENT HOOD

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.
