  • Patent number: 11016014
    Abstract: The present disclosure provides a method of determining an optimal filter life cycle between replacements of a filter in a ventilation system. The method comprising performing the following steps in a processing device: receiving at least one filter hardware value, receiving at least one filter use value, receiving a plurality of measured data points, and determining the optimal filter life cycle by minimizing a total filter resource consumption composed of a first factor, a second factor, providing a plurality of predicted data points, grouping successive measured data points into windows, and assigning the identified maximum pressure drop as a maximum pressure drop for all measured data points of that window.
    Type: Grant
