The Redline Emissions Products Born On Weight is designed for heavy duty diesel particulate filters. Users can check the functionality and health of the DPF by comparing its current weight to its "Born on Weight." Knowing the original weight of a DPF provides key information to aid in the cleaning process, the company says. Weighing every filter prior to servicing gives users a point of reference to understanding how dirty the filter is. Re-weighing the filter after initial cleaning determines whether the filter is thoroughly cleaned.
