The invention is a transformable and collapsible filter frame which can support various air intake filtering medias for internal combustion engines. The first form of the filter frame of the invention can be compared to the shape of a carousel. The carousel configuration which forms the filter frame is a separate entity from the filtering media. The invention which is a frame enables re-usable filtering medium to be applied over its surface. This re-usable filtering medium is a practical alternative to the existing air filters which are thrown away after they have been in use for a period of time and become inefficient in air filtration. A re-usable filtering media on the invention may be a polyurethane foam which can be manufactured in various shapes and sizes. The tailor made filtering media would fit around the invention filter frame. The carousel filter frame structure is comprised of expandable and adjustable parts which are filter frames in the form of rings and struts, when integrated both are used as supporting members. The rings and struts can be easily disassembled and reassembled by various connecting means. The said parts are made of durable materials, such as plastic, metal or wood for non-throw away permanent usage. The carousel filter body structure can be easily transformed into various configurations and sizes with the adaptable filter frame parts as desired to form other different types of filter shapes or forms. One shape the carousel can be split to form various shapes of filter frames such as a shield, circle, cylindrical, cone, an oval, square, rectangle and configurations resembling a circus tent and race-track. |
