Best For

Pool owners replacing an existing Hayward C150S or choosing a single-element cartridge filter for a properly sized circulation system. It is especially useful where simple cartridge access, no backwashing, and compact equipment-pad dimensions are priorities.

Why This Matters

• A 150 sq. ft. single cartridge provides a large filtering surface while keeping routine cartridge service simple.
• Confirming plumbing connections and service clearance before purchase helps prevent installation problems.
• Matching the filter model also makes future replacement-cartridge selection easier.

Common Signs You Need This / Use This When

• You are replacing an existing Hayward C150S or W3C150S filter.
• Your current filter tank or internal components require replacement and a complete filter is the better repair path.
• You want a cartridge filtration system that does not require backwashing.
• Your installer has confirmed that 150 sq. ft. of filtration area and the C150S flow rating are appropriate for the system.

Product Specifications

Compatibility / Fitment Notes

W3C150S identifies the Hayward SwimClear C150S 150 sq. ft. filter. When replacing an existing filter, confirm the model number on the filter label rather than selecting by filtration area alone. Verify the 2" x 2½" union connection arrangement, available equipment-pad space, system flow requirements, and at least 15" of overhead clearance for filter-head and cartridge removal.

Hayward lists CX150XRE as the replacement cartridge element for the C150S. If you are purchasing a replacement element rather than the complete filter, match the filter model before ordering.

Installation / Use Notes

Have a qualified pool professional verify filter sizing, plumbing configuration, equipment-pad clearance, and circulation-system flow before installation. Install and operate the filter according to Hayward's instructions. Never open or service a pool filter while the system is pressurized; follow the manufacturer's shutdown and pressure-relief procedures before maintenance.

Buy with Confidence

Benchmark Pool Supply helps pool owners identify complete equipment and replacement parts using model numbers, plumbing requirements, and real pool-equipment knowledge. If you are replacing an existing filter, use the model label and equipment-pad details to confirm the correct match before ordering.
