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), while good quality original paper filters range from 97% to 99%, and foam filters 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 official Aprilia bike raced with a DNA filter without any dust penetration, demonstrating superior performance compared to foam filters. Do I always need to apply oil after cleaning the filter? Yes, you should never use an unoiled DNA filter. Oil is a crucial part of the filter media. After maintenance, always apply special DNA filter oil. How often should I clean my DNA filter? Maintenance intervals depend on the operating environment. We recommend once a year or every 15,000-30,000 km. A simple way to check is to look at the metal mesh on the dirty side: if it is visible, the filter is still usable.
