  • LAMINATED SHEET, CYLINDRICAL FILTER ELEMENT, AND FILTRATION KIT USED TO PERFORM WATER FILTRATION
    Publication number: 20240367076
    Abstract: The present invention provides a laminated sheet, a cylindrical filter element, and a filtration kit that are used to perform water filtration. Specifically, the laminated sheet used to perform water filtration includes: a pre-filtration layer, the pre-filtration layer including a first fiber having a diameter within a range of 1-5 ?m and a second fiber having a diameter within a range of 200-900 nm, and the pre-filtration layer having a pore diameter within a range of 0.2-1 ?m; and a fine filtration layer, the fine filtration layer having a pore diameter within a range of 0.02-0.5 ?m, wherein the pore diameter of the pre-filtration layer is greater than the pore diameter of the fine filtration layer. The laminated sheet used to perform water filtration and the cylindrical filter element and the filtration kit including the same according to the technical solution of the present invention have an extremely small pressure difference, high filtration efficiency, and a long service life.
