Continue until the runoff is clear. Do not use a pressure washer at any setting; high-pressure spray permanently compresses the pleat fibers. Reinstall the cartridge, close the EasyLok ring, open the air relief valve, and restart the pump. Note the pressure when the system is running cleanly; this is the baseline for future cleaning decisions. A rise of 8 to 10 PSI above that baseline signals cleaning is due.\u003c\/p\u003e\n\n  \u003ch3\u003eDeep Cleaning and Cartridge Replacement\u003c\/h3\u003e\n\n  \u003cp\u003eRoutine rinsing removes surface debris but not the oils, sunscreen residue, and mineral scale that embed in the pleat fibers over a season.

The W3C150S is positioned for smaller and mid-size pools, spas, and water features, while the older C150S was rated for larger in-ground pools. If you are replacing an existing C150S, verify connection sizes and footprint before ordering.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes the W3C150S require any tools for cartridge removal?\u003c\/summary\u003e\n    \u003cp\u003eNo. The EasyLok ring design provides single-turn access to all internal components without tools. The only step required before opening is turning off the pump and releasing tank pressure through the air relief valve.

A filter with lower head loss allows the pump to achieve the required flow rate at a lower speed or for a shorter run time, which reduces electricity consumption. The W3C150S's hydraulic design minimizes resistance so variable-speed pumps can run efficiently at lower speeds while still achieving proper pool turnover.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003ch2\u003eHayward SwimClear W3C150S Cartridge Filter Documentation\u003c\/h2\u003e\n\n  \u003cdiv class=\"doc-links\"\u003e\n    \u003cul\u003e\n      \u003cli\u003e\n        \u003ca href=\"\/docs\/hayward-swimclear-w3c150s-owners-manual.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\n          Hayward SwimClear W3C150S Cartridge Filter Owner's Manual (Installation and Operating Instructions)\n        \u003c\/a\u003e\n      \u003c\/li\u003e\n      \u003cli\u003e\n        \u003ca href=\"\/docs\/hayward-swimclear-w3c150s-parts-diagram.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\n          Hayward SwimClear W3C150S Cartridge Filter Parts Diagram and Replacement Part Numbers\n        \u003c\/a\u003e\n      \u003c\/li\u003e\n      \u003cli\u003e\n        \u003ca href=\"\/docs\/hayward-cx150xre-cartridge-replacement-guide.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\n          Hayward CX150XRE Replacement Cartridge Element Guide\n        \u003c\/a\u003e\n      \u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\/\",\n  \"@type\": \"Product\",\n  \"name\": \"Hayward SwimClear 150 Sq Ft Single-Element Cartridge Pool Filter | W3C150S\",\n  \"description\": \"The Hayward SwimClear W3C150S is a 150 sq ft single-element cartridge pool filter for smaller and mid-size in-ground pools, spas, and water features. 56 GPM design flow rate, 10-15 micron filtration, 50 PSI maximum working pressure.
