Abstract
An operational state of a system for filtering imaging by-products from an airflow is monitored by comparing a measurement of the flow rate of the airflow to a threshold. Additionally, an operational state of a filtration element is monitored by accumulating a count indicative of the remaining capacity of the filtration element in a memory device coupled to the filtration element.
