The Donaldson Filter Minder is designed to monitor truck engine air filters using the vehicle's own telematics system. Filter Minder wireless sensors and receivers send filter performance data to the cloud, and predictive analytics inform the fleet manager when individual trucks are approaching optimal filter life. Filter Minder connected technology works by prompting filter changes based on filter condition, rather than on scheduled maintenance intervals. The system also helps ensure that the right filters are in inventory when maintenance is due.
