Filtering out exhaust problems June 25th 2009 EHC Teknik has developed a range of exhaust filters that fit directly to a vehicle tailpipe and work as soon as the vehicle engine is started and require no preheating or outside power supply. The filters are said to remove 99.92% of all particles. By trapping the particles they capture the materials that are harmful to health and reduce the amount of noxious gases.
New generation engines produce 15 to 35 times smaller particles than older engines due to improved fuel burning and exhaust recirculation.
Catalysers are available to reduce smells even further.
