Embodiments herein relate to monitoring systems that can learn patterns of filtration system operation and then use the learned patterns to monitor ongoing filtration system operation/performance. In a first aspect, a monitoring system for an air filtration system is included having a control circuit, and a pressure sensor, wherein the pressure sensor is in electronic communication with the control circuit. The monitoring system can be configured to store data reflecting signals of the pressure sensor, evaluate the stored data representing a first time period to derive a valve operating pattern, and compare data from the pressure sensor obtained after the first time period against the derived valve operating pattern to identify an abnormal valve event.
