Its just a centrifuge run off oil pressure and filters out particles as small as 1/10 of a micron. And yes you still use your standard oil filter. Its just a secondary filter. Running mobil delvac full synthetic with a donaldson spin on filter and the centrifuge I run 15k before changing oil and filter and thats only for peace of mind. The oil still looks slighty clear when drain it.
