Frequently asked questions Does the DNA filter offer the same level of protection as the original filter? Yes, and even better. DNA filters have a minimum filtration efficiency of 98% (ISO 5011 test). Good quality original paper filters range from 97% to 99%, while foam filters range from 92% to 97%. Can I use the DNA filter for off-road use? Yes, DNA has developed a unique filter media, perfect for off-road use. During the 2011 Dakar Rally, an Aprilia 450 Rally bike raced with a DNA filter without any dust ingress, demonstrating superior performance compared to foam filters. Do I always need to apply oil after cleaning the filter? Yes, never use the DNA filter without oil. Oil is a crucial part of the filter media. After maintenance, always apply special DNA filter oil, not just any oil. How often should I clean the DNA filter? Maintenance intervals depend on the operating environment. It is recommended once a year or every 15,000-30,000 km. A simple way to check is to see if the wire mesh on the dirty side is visible: if it is covered with debris, the filter needs cleaning.
