Air filtration indicator

A fluid filtration system, such as an ambient air cleaner, employs a measurement mechanism to determine the amount of fluid flow through the system. The measurement system provides data or actuates an indicator. The indicator may have a pointer to indicate fluid flow along a gradient display that contains numeric information and/or is color coded. Alternatively, fluid flow may be displayed electronically. The indicator may be protected within a separate housing that projects from a filtration unit housing or may be disposed within a recess of the filtration unit housing.
