Strainer magnets

A fluid filter assembly comprising:

• an annular filter element adapted for insertion into a filter housing, said filter element being pleated and having an exterior surface constructed of nonmagnetizable material through which a fluid to be filtered flows into the interior of said filter element;
• an annular band of magnet material, said magnet material being formed from a pliable, relatively nonresilient material to adapt itself to the exterior surface of filter elements of different diameters and having a plurality of magnet members embedded therein throughout its length to magnetically attract particles to it throughout its length;
• and
• a spring member removably mounted to the ends of said band of pliable magnet material for fastening said ends together around the exterior surface of said filter element intermediate said filter element and the filter housing whereby in operation the band is in direct fluid contact with the fluid.
