Key Benefits + Cartridge Filtration and Plumbing Fit
- 425 square feet of filtration area supports debris removal in a properly sized pool circulation system.
- Four reusable cartridge elements provide filtration without sand or D.E. media.
- Cartridge cleaning replaces routine backwashing.
- Union connections accommodate 2-inch or 2½-inch plumbing; confirm the installation layout before ordering.
- Removable tank top provides access for cartridge service without disconnecting the main plumbing.
Quick Product Summary
The Hayward SwimClear W3C4030 is a 425-square-foot, four-element cartridge pool filter for in-ground pool circulation systems. It captures suspended debris to support clear water and is an option for a new equipment installation or replacement filter selected by a pool professional. Before ordering, verify system flow, plumbing connections and equipment-pad space; filtration area alone does not establish compatibility.
Best For
Pool owners and service professionals selecting a complete cartridge filter for an in-ground pool, replacing an aging filter assembly, or planning a move from sand or D.E. filtration with appropriate plumbing changes.
Why This Matters
- Filter selection affects both water filtration and equipment fit; matching the system helps avoid buying an unsuitable assembly.
- Reusable cartridges offer a different maintenance routine from a backwashed filter, so consider access and cleaning before choosing.
- The exact model matters when buying replacement elements and seals; keep W3C4030 and the installed filter label available for future parts orders.
Common Signs You Need This / Use This When
- Use this when a pool professional has selected a 425-square-foot cartridge filter for your circulation system.
- Consider a complete replacement when inspection identifies a damaged or unsuitable existing filter assembly.
- If only the cartridges need replacement, identify the correct elements before purchasing an entire filter.
- Cloudy water, rising pressure or weak circulation can have several causes. Diagnose the system before treating a new filter as the solution.

Compatibility / Fitment Notes
Select this filter by the needs of the complete circulation system, including the pump’s operating flow and existing plumbing. A matching pipe diameter does not guarantee that an old filter’s unions, connection spacing or equipment footprint will transfer directly. Have the installer check the proposed connection arrangement and allow room for the tank top and cartridges to be removed for service.
W3C4030 identifies the complete filter product. When ordering maintenance parts later, match the installed equipment label and the relevant Hayward parts diagram. Do not choose replacement cartridges by approximate appearance or total filtration area alone.
Installation / Use Notes
Have a qualified pool professional install and commission the filter according to Hayward’s instructions. Confirm system flow, plumbing connections and service access before installation. Keep the owner’s manual and the initial clean-filter pressure reading for future maintenance. Follow the manufacturer’s inspection and cartridge-cleaning guidance, and have pressure-system service performed safely by a qualified professional.
Buy with Confidence
Choose the Hayward SwimClear W3C4030 from Benchmark Pool Supply with clear product identification and practical selection guidance. Bring your existing filter model, pump details and plumbing information when asking about replacement options so the equipment can be checked against your installation.
Frequently Asked Questions
Is W3C4030 a complete filter or a replacement cartridge?
W3C4030 identifies the Hayward SwimClear 425-square-foot filter assembly. If you only need replacement cartridges, match the installed filter model to its parts diagram before ordering.
Will this filter work with my existing pool pump?
Compatibility depends on operating flow, plumbing and the overall system. The published design flow is 150 GPM; have a pool professional confirm suitability rather than selecting by pump horsepower alone.
Does the SwimClear W3C4030 need sand, D.E. powder or backwashing?
No. It uses reusable cartridge elements, which are cleaned according to Hayward’s instructions instead of routine backwashing.
What plumbing connections should I check?
The filter uses union connections for 2-inch or 2½-inch plumbing. Confirm your pipe size, connection layout, required fittings and service access before ordering.
Should a professional install this pool filter?
Yes. Have a qualified pool professional install and service it according to Hayward’s instructions. Pool filtration equipment operates under pressure, so this page is not an installation procedure.
