ABSTRACT:
A transformable and collapsible filter frame which can support various air intake filtering media for internal combustion engines. One form of the filter frame corresponds generally to the shape of a carousel. The frame facilitates replacement of reusable filtering medium to be applied over its surface. The filtering media may be a polyurethane foam. The carousel filter frame structure includes expandable and adjustable parts, rings and struts which, when integrated are used as supporting members. The rings and struts include connecting members and can be easily disassembled and reassembled. 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 of the carousel can be split to form various shapes of filter frames such as a circle, cylinder, shield, cone, oval, square, rectangle and various combinations thereof. Advantageously, the reusable filtering medium and adjustable frame is a practical alternative to the existing air filters which are thrown away after a single use.
