Abstract
This disclosure relates generally to a filter media that can be used to filter a spa, hot tub, or pool. The filter media can include a body with a top surface, a bottom surface, and a plurality of pleats. A border is joined and surrounding a periphery of the body, the border for maintaining a planar shape of one or more of the top surface and bottom surface of the filter media.
Claims20
A filter media for filtering water in a pool or spa comprising:
- a plurality of pleats formed of a filter material, the pleats formed by applying a layer of adhesive to a top surface of the filter material, including over pleat valleys of the top surface and over pleat peaks of the bottom surface, and folding the filter material into pleats, the plurality of pleats arranged in a plurality of sections, where each section is separated from an adjacent section by the layer of adhesive and each section is adhered to the adjacent section through the layer of adhesive;
- and
- a border joined to and surrounding a periphery of the filter media, the border for maintaining a planar shape of a bottom surface of the filter media and the border being made of the filter material, and the border for maintaining the consistent spacing along the length of the pleat between each pleat of the plurality of pleats within each section;
- each pleat of the plurality of pleats extending across a width of the filter media,
- each pleat of the plurality of pleats comprising a consistent spacing along a length of the pleat;
- and
- the plurality of pleats being uniformly spaced apart from each other along a length and/or width of the filter media, such that water passing through the filter media passes through an entirety of each pleat.

A filter media for filtering water in a pool or spa, the filter media comprising:
- a body comprising a top surface, a bottom surface, and a plurality of pleats formed of a filter material and arranged in a plurality of sections where each section is adhered to an adjacent section through a layer of adhesive, such that each pleat of the plurality of pleats is adhered to two sections, each pleat of the plurality of pleats comprising a consistent spacing along a length of the pleat between each pleat of the plurality of pleats, such that fluid passing through the filter media is able to pass through an entirety of each pleat;
- the layer of adhesive applied to a top surface of the filter material, including over pleat valleys of the top surface and over pleat peaks of the bottom surface;
- and
- a border joined to and surrounding a periphery of the body, the border for maintaining a planar shape of one or more of the top surface and bottom surface of the filter media, and the border for maintaining the consistent spacing along the length of the pleat between each pleat of the plurality of pleats within each section.
1 more element
A method of filtering water in a pool or spa, the method comprising:
- selecting a filter media,
- wherein the filter media comprises a body comprising an outer surface, an inner surface, and a plurality of pleats arranged in a plurality of sections, each section of the plurality of sections adhered to an adjacent section through a layer of adhesive, each pleat comprising a consistent spacing along a length of the pleat between each pleat, the layer of adhesive applied to a top surface of the filter material, including over pleat valleys of the top surface and over pleat peaks of the bottom surface, the layer of adhesive maintaining the consistent spacing such that water passing through the filter media is able to pass through an entire length of each pleat;
- and a border surrounding the body and for maintaining a planar shape of the outer surface and the inner surface of the filter media, the border and the body comprising the same filter material;
- placing the filter media within a filter media housing;
- and
- passing water through the filter media, from the outer surface to the inner surface, the water able to pass through the entire length of each pleat of the plurality of pleats.
