@m0t0cr0ss17 All of our filters are tested with fine and course dust in the ISO5011 test. Over 11% of the course dust is 5.5 microns in diameter (size of a red blood cell), fine dust being smaller, and we achieve 96-99% efficiency. A dust partial this small cannot cause damage to an engine; carbon from the combustion chamber that is left behind is a larger particle then this. Please refer to our website for more test and warranty information.
