Abstract
A method for determining a service life for a filter includes measuring exposure data and calculating a service life estimate based on the exposure data. The service life estimate is representative of an estimated exposure time that the filter is exposed to ambient conditions represented by the exposure data before the contaminant passes through the filter at a breakthrough concentration. The method also includes obtaining environmental data and establishing a predicted service life based on the environmental data. The predicted service life is representative of a predicted exposure time that the filter is exposed to the ambient conditions represented by the environmental data before the contaminant passes through the filter at the breakthrough concentration. The method further includes determining the service life for the filter based on a comparison of the estimated and predicted service lives.
