An air filter health monitoring system (122) includes a filter (114) spanning an air passage for filtering solids and/or liquids out of an air flow passing through the air passage. An illuminator (124) is positioned on a first side (126) of the filter and directed to illuminate the filter (114). An illumination sensor (128) is positioned on a second side (130) of the filter. The illuminator (124) and illumination sensor (128) can each be spaced apart from the filter (114). The filter (114) can be installed in a galley insert and can include a reticulated filter medium folded in a v-shape over a v-shaped grid work.
