| Zusammenfassung: | The present invention involves using a melt-blowing process to make a filter medium defining pores having a pore size of between 3 and 12 microns. The filter medium is made of a thermoplastic polymer and is adapted for use in an internal combustion engine air filter. A profile is used in the melt-blowing process to mold melt blown fibers into the filter medium. |
