Frequently Asked Questions Does the DNA filter offer the same level of protection as the OEM filter? Yes, and even better. DNA filters have a minimum filtration efficiency of 98% (ISO 5011 tested). Good quality OEM paper filters range from 97% to 99%, while foam filters range from 92% to 97%. What is filtration efficiency? Filtration efficiency is the amount of dirt the filter can retain to protect the engine. For example, a DNA filter retains 98-99 grams for every 100 grams of dirt received, even for fine particles down to 5 microns. Can I use the DNA filter for off-road use? Yes, DNA has developed a unique filter media, perfect for off-road use. Successfully tested at Dakar 2011, it proved to let no dust through and to last longer than foam filters, debunking the myth that only the latter are suitable for off-road. 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 wire mesh on the dirty side: if it's visible, the filter is still usable; if it's completely covered, it needs to be cleaned.
