Sand, Cartridge, or DE — Which Hayward Filter Is Right for You?

Hayward makes all three major pool filter types, each with its own strengths:

Sand Filters like the ProSeries and S-Series are the most low-maintenance option. They backwash to clean, have a long media lifespan (5–7 years), and are ideal for pool owners who want simplicity. A great choice for above-ground and in-ground pools alike.

Cartridge Filters like the StarClear and SwimClear series offer finer filtration than sand — down to 10–15 microns — without the need to backwash. Just remove and rinse the cartridge. They're water-efficient and popular with homeowners and service techs who want clean water with minimal hassle.

DE Filters like the Perflex and Pro-Grid series deliver the finest filtration available, capturing particles as small as 3–5 microns. They require DE powder after each backwash but produce exceptionally clear water — the top choice for pools with high bather loads or demanding water clarity standards.

Sizing Your Hayward Filter: What Pool Pros Know

Filter sizing is one of the most common mistakes in pool equipment selection. An undersized filter leads to cloudy water, short filter cycles, and premature wear. Hayward recommends sizing your filter based on your pool's volume and pump flow rate — always err toward the larger model.

As a general rule: match your filter's flow rating (GPM) to your pump's output, and make sure the filter's turnover capacity handles your full pool volume within 8 hours. Hayward's SwimClear C4030 cartridge filter, for example, handles pools up to 40,000 gallons and flows up to 100 GPM — a common spec for mid-size in-ground pools.

All Hayward filters are compatible with Hayward pumps and plumbing using standard 1.5" and 2" fittings, and most drop in as direct replacements for other major brands with minimal replumbing. If you're unsure which model fits your setup, our team is available to help — or browse by filter type above to narrow it down.

Frequently Asked Questions

What is the best Hayward pool filter for a residential in-ground pool?
For most residential in-ground pools, the Hayward SwimClear cartridge filter or ProSeries sand filter are the most popular choices. Cartridge filters offer finer filtration and no backwashing, while sand filters are lower maintenance and great for larger pools. If water clarity is the top priority, a Hayward DE filter like the Pro-Grid will deliver the best results.
How often should I clean my Hayward pool filter?
Sand and DE filters should be backwashed when the pressure gauge reads 8-10 PSI above the clean starting pressure, typically every 2-4 weeks during swim season. Cartridge filters should be rinsed every 4-6 weeks and deep cleaned with a filter cleaner solution every season. DE filters also require fresh DE powder after each backwash.
Are Hayward filters compatible with other brand pumps?
Yes. Hayward filters use standard 1.5" and 2" pipe fittings and are compatible with pumps from Pentair, Jandy, and other major brands. In most cases they can serve as direct replacements with minimal replumbing required.
What size Hayward filter do I need for my pool?
Filter size depends on your pool volume and pump flow rate (GPM). As a rule, your filter should be rated to turn over your pool's full volume within 8 hours at your pump's flow rate. Hayward offers sizing guides for each filter series, and EZ Pools can help you match the right model to your system.
Does EZ Pools ship Hayward filters fast?
Yes. EZ Pools stocks Hayward filters at fulfillment centers in New Jersey, Colorado, and Jacksonville, Florida, enabling fast shipping to most of the continental US. Many orders placed before 2 PM ET ship same day.
