As a material for a diesel particulate filter, metal fiber shows better mechanical and thermal characteristics than ceramic. To show the possibility of the application to the metal fiber filter, the performances of the 1^st and 2^nd prototypes were tested in this study. The 2^nd prototype was improved in filter design and pore structure based on the test results of the 1^st prototype. The 2^nd prototype showed 50~85% of PM reduction and had a good performance of particle number reduction during steady state engine operation.
