◆ Three-layer deep-layer melt-blown filter structure provides high dirt holding capacity and prolongs service life
◆ The surface is specially treated to increase the effective filtration area and increase the pressure difference
◆ The externally sparse and internally dense stepped filter structure disperses the water flow direction and reduces the water flow resistance
◆ After special treatment, the surface and inner holes of the filter element do not fluff, reducing clogging
◆ 100% pure polypropylene, without adding chemical adhesives, safe, healthy, good chemical compatibility
