A fluid cleaner system including a filter element of substantially cylindrical construction corrugated in a cross-section including the axis thereof to allow a fluid to flow axially from one end to the other end. The filter element is supported and sealed by support means and sealing means and mounted in a case and a cap. The support means and sealing means are simple in construction and yet allow the filter element to fully perform its function.

A fluid cleaner system comprising: a casing and a cap coupled to each other for defining therein a filter chamber; and a filter unit disposed in said filter chamber having a filter element and a support device, said filter element having two-dimensional wave forms and being formed of a trapezoidal or a sectorial filter sheet by folding the same along a plurality of folding lines parallel to a base line of said trapezoidal or sectorial filter sheet, wherein said support device supports said filter element thereon and holds the same in said filter chamber, said support device comprises: an inner frame having an inner annular groove for receiving therein the innermost peripheral portion of said filter element; an outer frame having an outer annular groove for receiving the outermost peripheral portion of said filter element, said outer frame also having a circular flange extending radially outwardly from said outer annular groove and said circular flange being interposed between outer circular peripheral portions of said casing and cap; and a plurality of webs connecting said inner and outer frames with each other and supporting the lower fold edges of said filter element thereby to prevent distortion of said element on down draft of fluid therethrough.
