Abstract: A method for capturing small metal particles within an oil filter can. The method uses a flexible belt incorporating a number of pockets. Magnets are contained within the pockets, with one magnet per pocket being preferable. The pockets are sealed so that the belt and magnets operate as a unified whole. The belt is wrapped around an oil filter and held in place via the attraction between the magnets and the metal oil filter can. No additional securing mechanism is needed. The belt may be wrapped around oil filters of various sizes with no need for any alterations.
