HJS Cityfilter

HJS diesel particle filters guarantee clean air. They hold back the soot particles effectively in their interior, including fine-grain dust, and clean themselves of deposited soot continuously and autonomously. The sintered metal filter technology developed by HJS and distinguished with the German Environmental Prize guarantees this. HJS filter solutions are TÜV approved and are recommended by the ADAC. All systems have the valid general operating permit (ABE) and were developed specially for retrofit. They are maintenance-free and have a life as long as the vehicle.
