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 OEM 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 medium, perfect for off-road use. During the 2011 Dakar Rally, an official Aprilia 450 Rally bike competed with a DNA filter with impressive results: no dust ingress and only one filter needed per day, compared to 2 or 3 foam filters for other bikes. How often should I clean my DNA filter? Maintenance intervals depend on the operating environment. Once a year or every 15,000-30,000 km is recommended. An easy way to check is to see if the wire mesh on the dirty side is visible: if it is, the filter can still be used; if it is completely covered in debris, it needs cleaning. Can I use gasoline, thinners, or compressed air to clean my DNA filter? Absolutely not. You must treat the DNA filter like a delicate fabric. Every DNA filter package and service product includes detailed cleaning instructions. The procedure is very simple to follow.
