[0012] Furthermore, the filtration accuracy of the coarse filtration membrane is 0.03 microns, and the filtration accuracy of the fine filtration membrane is 0.01 microns.

[0013] Furthermore, the first antibacterial layer is a cotton net formed by opening, carding and cross-lapping zinc ion antibacterial polyester staple fibers, and the thickness of the cotton net is 0.1 mm.

[0014] Furthermore, the second antibacterial layer is a cotton net formed by mixing, combing and cross-laying polypropylene staple fibers treated with Dewei magnetic antibacterial technology, and the thickness of the cotton net is 0.1 mm.

[0015] Furthermore, the adsorption layer is a cotton net formed by opening, combing and cross-laying bamboo charcoal fibers, and the thickness of the cotton net is 0.1 mm.
