A filter for removal of magnetic particles in which a liquid flows through a first compartment containing magnetic balls tightly packed together so that there is no direct flow path but only around these magnetic balls. Increased mixing of flow coupled with strong intensity of a magnetic field across the flow promotes better attraction and retention of the magnetic particles on the magnetic balls. The second compartment contains commonly known porous materials of known porosity to remove smaller non-magnetic particles. The filter is particularly useful as a fuel or oil filter for an internal combustion engine. In one embodiment, the magnetic portion is made removable and individually replaceable to extend the life of the filter. The filter is capable of removing magnetic particles for an extended period of time without clogging.

[What I claim is:] [1.]a filter housing with a filter inlet and a filter outlet;a first compartment having a first inlet, a middle portion, and a first outlet, said first inlet being in fluid communication with said filter inlet said first middle portion containing a plurality of permanent magnets of generally round shape, anda second compartment having a second inlet, a second middle portion, and a second outlet, said second inlet being in fluid communication with said first outlet, said second middle portion containing a porous sheet material, said second outlet being in fluid communication with said filter outlet, reby said permanent magnets being adapted to attract and retrain said magnetic particles as said fluid is passed through said first compartment of said filter.
