Worldwide efforts, to curtail particle emissions from combustion engines, have produced a plethora of technologies. Not all of them are Best Available Technology as required by law to eliminate carcinogenic substances. The project VERT had been the pioneer from 1993. The AKPF (Working Group for Particle Filters) subsequently collaborated with the regulatory authorities and industrial partners to formulate a set of criteria. These include highest requirements in filtering the alveoli-intruding solid particles, preventing secondary emissions, guarantee dependability and cost effectiveness of the systems and assure best retrofit practice. VERT® only approves systems, which comply with the BAT definition and are proven in field deployment; both new and retrofitted older deployed Diesel engines.
High filter quality also results in cost effectiveness because it diminishes treatment costs for many serious ailments. These include cancer, cardiovascular, allergies, asthma and probably even Parkinson’s, Alzheimer’s and other widespread diseases. VERT® is highly committed to implement the latest medical and scientific findings. The filter approval criteria will be periodically adapted to reflect technological advances. Hence, this filter list will be updated twice a year.
The VERT® Association aims to provide methods to very efficiently combat both emission toxicity and black carbon induced global warming. Particle filters facilitate a sustainable environment.

This VERT® Filter List is an international industrial standard, not legally binding. This standard has however already become a legally binding code in a variaty of countries for different applications where authorities have required “Best Available Technology” within regulations.
