Abstract
A filter status module for use with a container based filtration device includes a dispensing sensor and a user interface communicatively coupled to a processing unit. The processing unit counts a number of dispensing events, duration and/or angle of tilt signaled by the dispensing sensor and outputs a filter status on the user interface as a function of the number of dispensing events, duration and/or angle of tilt. The processing unit may further track an elapsed period of time from insertion of a new filter and output the filter status as a further function of the elapsed period of time.
