◆ Larger outer diameter and volume can provide more filtration area and greater circulation, prolong the filter replacement cycle
◆ Three-layer deep-layer melt-blown filter structure provides high dirt holding capacity and prolongs service life
◆ 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
