Q 14 . Is there any particle left in liquid after filtrating？
It is clearer to give an example.
If you use filters with micron 0.2um correctly, numbers of 0.2um particles left in liquid depend on whether use nominal filters (nom.) or absolute filters (abs.).
So called “abs. 0.2um” means the efficiency of capture particles bigger than 0.2um is 99.9%.
Theoretically, left particles are almost smaller than 0.2um.
