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.

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.

Because the W3C3030 allows individual element replacement, inspect each element's condition at every cleaning rather than waiting for a full set to fail.\n  \u003c\/p\u003e\n\n  \u003ch3\u003ePump Pairing and Flow\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C3030's 122 GPM design flow rate fits the output of most standard residential pump configurations for in-ground pools. For variable-speed pump installations, lower speeds during overnight filtration reduce electrical costs while keeping the filter operating at pressures that extend element life. If your pool also has a spa or water features that draw higher combined flow at full speed, verify the total system GPM at each operating mode stays within the filter's rated ceiling.

Install all four CX580XRE cartridges before closing the lid. Prime by running the pump with the air relief valve open until a steady stream of water (not air) flows from the port, then close the valve. Record the gauge reading as the clean baseline: a rise of 8 to 10 PSI above this number indicates cleaning is due.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWinterizing the W3C3030\u003c\/h3\u003e\n\n  \u003cp\u003e\n    At season end, remove all four CX580XRE cartridges, perform a full cleaning and soak cycle on each element, and inspect each carefully before storage.

Soaking all four elements overnight in a dedicated pool cartridge cleaning solution at the start of each swim season, and again during periods of heavy use, is the most reliable way to restore operating pressure to the recorded clean baseline and extend element service life.\u003c\/p\u003e\n\u003cp\u003eReplace a CX880XRE element when pressure does not return to the clean baseline after a full clean-and-soak cycle, when the pleats show visible tears or permanent compression, or when end cap cracking allows unfiltered water to bypass the media. Because the W3C4030 allows individual element replacement, inspect each element's condition at every cleaning rather than waiting for a full set to fail.\u003c\/p\u003e\n\u003ch3\u003ePump Pairing and Flow\u003c\/h3\u003e\n\u003cp\u003eThe W3C4030's 150 GPM design flow rate accommodates a wide range of residential pump configurations. For installations with variable-speed pumps, lower speeds during overnight filtration cycles reduce electrical costs while keeping the filter working at pressures that extend element life. Higher-speed runs for spa jets or water features sit comfortably within the filter's rated flow. Confirm at commissioning that the pump's output at each operating speed is appropriate for the filter and that the system does not consistently run near the rated maximum, which accelerates pleat wear.\u003c\/p\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe W3C4030 connects via CPVC 2\" or 2.5\" union couplings at the inlet and outlet. No multiport valve is needed. Connect pump discharge to the filter inlet and filter outlet to the pool return. The tank requires 58.5\" of vertical overhead clearance for cartridge removal during service; confirm this at the equipment pad before installation. Install all four CX880XRE cartridges before closing the lid. Prime by running the pump with the air relief valve open until a steady stream of water (not air) flows from the port, then close the valve. Record the gauge reading as the clean baseline: a rise of 8 to 10 PSI above this number indicates cleaning is due.\u003c\/p\u003e\n\u003ch3\u003eWinterizing the W3C4030\u003c\/h3\u003e\n\u003cp\u003eAt season end, remove all four CX880XRE cartridges, perform a full cleaning and soak cycle on each element, and inspect each carefully before storage. Store cartridges indoors in a dry location away from sunlight and freezing temperatures. Use the 1.5\" integral drain to fully empty the tank body, leave the lid open to allow residual moisture to evaporate, and store the tank in a protected location. In hard-freeze climates, bring the tank indoors or into an insulated space to prevent ice damage to the tank body and seals.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat replacement cartridge does the W3C4030 use, and how many are required?\u003c\/summary\u003e\n\u003cp\u003eThe W3C4030 uses four Hayward CX880XRE replacement cartridge elements, one per position in the Quad-Cluster manifold. Each element is 106 sq ft (7\" outer diameter, 25.5\" length). A full replacement set requires four CX880XRE units. Common aftermarket cross-references include Unicel C-7488 and Pleatco PA106.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the design flow rate for the W3C4030?\u003c\/summary\u003e\n\u003cp\u003eThe W3C4030 has a published design flow rate of 150 GPM per Hayward's documentation. Sustained operation consistently at or near the rated maximum accelerates element wear and shortens cleaning intervals, so the pump should be sized to meet the pool's daily turnover requirements rather than running at the ceiling continuously.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the W3C4030 require a backwash valve or drain line?\u003c\/summary\u003e\n\u003cp\u003eNo. The W3C4030 uses CPVC union coupling connections at the inlet and outlet as its only plumbing connections. There is no multiport valve and no backwash drain line. Cleaning is done by removing the four cartridge elements and rinsing them by hand with a garden hose.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use cartridges from the 325 or 525 sq ft SwimClear models in the W3C4030?\u003c\/summary\u003e\n\u003cp\u003eNo. The W3C4030 uses CX880XRE elements (106 sq ft each). The 325 sq ft model uses smaller CX580XRE elements and the 525 sq ft model uses larger CX1280XRE elements. Installing the wrong element results in improper manifold seating that allows unfiltered water to bypass the cartridge media. Always match replacement cartridges to the model number on the filter tank or in the owner's manual.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the W3C4030 differ from the 525 sq ft SwimClear model?\u003c\/summary\u003e\n\u003cp\u003eBoth models share the same 150 GPM design flow rate and four-element Quad-Cluster configuration. The 525 sq ft model provides an additional 100 sq ft of total filter area (131 sq ft per element vs. 106 sq ft per element) via larger CX1280XRE cartridges. The additional filter area extends the interval between required cleanings and provides more headroom for pools with consistently high debris loads, heavy bather traffic, or heated environments where filter demand is elevated year-round.

Once fully depressurized, open the one-piece clamp, lift the lid, and remove each CX1280XRE element individually. At 131 sq ft per element and 32.875\" in length, these are the largest cartridges in the SwimClear line; have a stable surface ready nearby and note which element came from which position so you can track wear differences across the Quad-Cluster over time.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Rinse each element top to bottom with a garden hose and spray nozzle, working between every pleat fold on all sides. Continue until the runoff runs clear. Do not use a pressure washer at any setting; high-pressure spray permanently compresses the pleat fibers and cannot be undone.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eDeep Soak Cleaning and Element Replacement\u003c\/h3\u003e\n\n  \u003cp\u003e\n    Surface rinsing clears the bulk debris load but does not remove oils, mineral scale, and fine organic compounds that work into the pleat material over a season. Soaking all four elements overnight in a dedicated pool cartridge cleaning solution at the start of each swim season, and again midway through periods of heavy use, is the most reliable way to restore operating pressure to the recorded clean baseline and extend element service life.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Replace a CX1280XRE element when pressure does not return to the clean baseline after a full clean-and-soak cycle, when the pleats show visible tears or permanent compression, or when end cap cracking allows unfiltered water to bypass the media. Because the W3C5030 allows individual element replacement, inspect each element's condition at every cleaning rather than waiting for a full set to fail. At this element size, indoor storage at season end makes a meaningful difference in protecting the pleat material and end cap seals from off-season UV and freeze damage.\n  \u003c\/p\u003e\n\n  \u003ch3\u003ePump Pairing and Flow\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C5030 shares the same 150 GPM design flow rate as the W3C4030, so the two filters suit similar pump configurations. The practical difference is filter area: 525 sq ft vs. 425 sq ft means the W3C5030 holds more debris before pressure rises to the cleaning threshold, extending the interval between service events under equivalent conditions. For installations where the pump output comfortably fits within 150 GPM and the driving consideration is minimizing cleaning frequency, the W3C5030 is the stronger choice. For variable-speed pump installations, lower speeds during overnight filtration cycles keep the filter operating at pressures that extend element life while reducing electrical costs.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C5030 connects via CPVC 2\" or 2.5\" union couplings at the inlet and outlet. No multiport valve is needed. Connect pump discharge to the filter inlet and filter outlet to the pool return. This tank requires 68.5\" of vertical overhead clearance for cartridge removal during service, which is 10\" more than the W3C4030; verify this at the equipment pad before committing to placement. Install all four CX1280XRE cartridges before closing the lid. Prime by running the pump with the air relief valve open until a steady stream of water (not air) flows from the port, then close the valve. Record the gauge reading as the clean baseline: a rise of 8 to 10 PSI above this number indicates cleaning is due.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWinterizing the W3C5030\u003c\/h3\u003e\n\n  \u003cp\u003e\n    At season end, remove all four CX1280XRE cartridges, perform a full cleaning and soak cycle on each element, and inspect each carefully before storage. At this element size, indoor storage in a dry location away from sunlight and freezing temperatures is particularly important for protecting the pleat material and end cap seals. Use the 1.5\" integral drain to fully empty the tank body, leave the lid open to allow residual moisture to evaporate, and store the tank in a protected location. In hard-freeze climates, bring the tank indoors or into an insulated space to prevent ice damage to the tank body and seals.\n  \u003c\/p\u003e\n\n  \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat replacement cartridge does the W3C5030 use, and how many are required?\u003c\/summary\u003e\n    \u003cp\u003eThe W3C5030 uses four Hayward CX1280XRE replacement cartridge elements, one per position in the Quad-Cluster manifold.

The difference between the two models is filter area (525 sq ft vs. 425 sq ft), not flow capacity. Sustained operation consistently near the rated maximum accelerates element wear and shortens cleaning intervals, so the pump should be sized to meet the pool's daily turnover requirements rather than running at the ceiling continuously.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes the W3C5030 require a backwash valve or drain line?\u003c\/summary\u003e\n    \u003cp\u003eNo. The W3C5030 uses CPVC union coupling connections at the inlet and outlet as its only plumbing connections.

The W3C4030 uses shorter CX880XRE elements and the W3C3030 uses CX580XRE elements. Installing the wrong element results in improper manifold seating that allows unfiltered water to bypass the cartridge media.
