Abstract
A filter system includes a housing, a filter medium disposed within the housing and a optical analyte sensor also disposed within the housing in fluid communication with the filter medium. The optical analyte sensor includes a detection medium that changes at least one of its optical characteristics in response to an analyte. The filter system further includes an optical reader having at least one light source and at least one detector. The optical reader is attached to the housing such that at least a portion of light emitted by at least one light source is reflected from the optical analyte sensor and captured by at least one detector.
