ABSTRACT A re-useable coffee, tea, brewing filter comprised of long-chain synthetic polymere or polyamide with the addition of polyethelene in the extrusion process, this synthetic fibre is then designed with interstices of a controlled and uniformed size and weight. This filter is heat set to a fluted frustum-conical, or funnel moulded shape. This filter needs no outside support skeleton or ribs to maintain its' shape, under any condition of distortion. This filter is soft and very flexible, But will automatically assume its' original shape. The upper rim of the filter is the only area of a solid non-porous medium, it is fused to a solid, which helps maintain its' strength in maintaining its' shape. The non-fluted flat area defines the bottom area, with the fluted walls urging the remainder of the filter material toward engagement with the filter basket or support structure side wall area. Differences in size of support basket and filter will automatically be accomodated by extension or compression of interstices in a controlled uniformed manner.
