1. A filter system comprising:
- a housing;
a filter medium disposed within the housing;
an optical analyte sensor characterized by a first region that exhibits a first response to an analyte of interest and a second region that exhibits a second, different, response to an analyte of interest, the optical analyte sensor comprising a detection medium and disposed within the housing such that the detection medium is in fluid communication with the filter medium; and
an optical reader comprising a first assembly comprising at least one light source and at least one detector and a second assembly comprising at least one light source and at least one detector;
wherein the optical reader is attached to the housing such that at least a portion of light emitted by at least one light source of the first assembly is reflected from the first region of the optical analyte sensor and captured by at least one detector of the first assembly, and at least a portion of light emitted by at least one light source of the second assembly is reflected from the second region of the optical analyte sensor and captured by at least one detector of the second assembly.

Abstract
A filter system includes a housing, a filter medium disposed within the housing, an optical analyte sensor, and an optical reader. The optical analyte sensor is characterized by a first region that exhibit a first response to an analyte of interest and a second region that exhibit a second, different, response to an analyte of interest. The optical analyte sensor includes a detection medium and is disposed within the housing such that the detection medium is in fluid communication with the filter medium. The optical reader includes at least one light source and at least one detector.
