description Methods for controlling air filtration in an enclosure include measuring contaminants in an internal and an external environment using respective internal and external contaminant sensors. An increase in a corrosion rate is determined for objects in the enclosure if unfiltered external air intake is increased for cooling based on the measured contaminants in the internal and external environments. An air pressure needed to filter external air using a filter in the filtered air intake is determined. An intake of unfiltered external air is controlled by bypassing the filter in the filtered air intake, based on the corrosion rate increase and the determined air pressure. A predicted filter lifetime is updated based on the intake of unfiltered external air. A warning is provided if the contaminant sensor information associated with the filter exceeds an instantaneous failure threshold or if the determined remaining filter lifetime falls below a filter lifetime threshold.
