A filter monitor system is provided in a bottled water cooler for automatically tracking a filter service interval, and for indicating that filter cleaning or replacement is required for continued efficient cooler operation. In the preferred form, the water cooler includes a thermoelectric chiller module for chilling at least a portion of water contained within a cooler reservoir. An air filter is mounted on a filter frame which is removably positioned for filtering air drawn by a fan to circulate over a heat sink associated with the thermoelectric chiller module. The filter monitor system includes a reset switch engaged by the filter frame to initiate and track a predetermined filter service time interval, such as thirty days, and to energize a signal such as an indicator light at the conclusion of this service interval to indicate that the air filter should be removed for cleaning or replacement.
