HJS Cityfilter

HJS diesel particulate filters ensure clean air. They effectively retain the soot particles, including fine dust, in their interior and continuously clean themselves of deposited soot. This is ensured by the sintered metal filter technology developed by HJS and awarded the German Environmental Prize. HJS filter solutions are TÜV-tested and recommended by the ADAC. All systems have a valid general operating permit (ABE) and have been specially developed for retrofitting. They are maintenance-free and last the life of the vehicle
