Shop Pool Filters by Type

Not sure which section to start in? Here's a quick breakdown:

Cartridge Filters — The most popular choice for residential pools. No backwashing required; just rinse or replace the cartridge element. Brands like Hayward SwimClear and Pentair Clean & Clear are top sellers.

Sand Filters — The simplest and most low-maintenance option. Backwash to clean. Great for above-ground and in-ground pools alike. Hayward ProSeries is the go-to in this category.

DE Filters— Finest filtration available, capturing particles down to 3–5 microns. Requires DE powder after each backwash. Best for pools that demand exceptionally clear water.

Replacement Filter Cartridges — Already have a cartridge filter and just need a new element? Shop OEM replacements from Hayward and Pentair, plus aftermarket options from Pleatco and Unicel.

Filter Media— Replace the sand, DE powder, or glass media inside your existing filter. Includes standard filter sand, zeolite, and glass filter media options.

Filter Valves — Multiport and push-pull valves for sand and DE filters. Hayward and Pentair replacement valves in 1.5" and 2" configurations.

What to Know Before You Buy a Pool Filter

The most common mistake when replacing a pool filter is undersizing. A filter that's too small for your pump's flow rate will clog quickly, run at high pressure, and wear out faster. Always match your filter's rated flow (GPM) to your pump's output, and make sure the filter can complete a full turnover of your pool's volume within 8 hours.

As a general sizing guide: pools up to 15,000 gallons pair well with a 100–150 sq ft cartridge filter or a smaller sand filter (S166T/ProSeries); pools in the 20,000–40,000 gallon range typically need a 200–325 sq ft cartridge or a mid-size sand or DE filter. For high-bather-load pools or commercial applications, a large DE filter or multi-element cartridge system is the right call.

If you're replacing an existing filter, check the model number on the tank — most Hayward, Pentair, and Jandy filters drop in as near-direct replacements with standard 1.5" or 2" plumbing connections.

Frequently Asked Questions

What type of pool filter is best for a residential in-ground pool?
Cartridge filters are the most popular choice for residential in-ground pools because they require no backwashing, use less water, and provide fine filtration down to 10-15 microns. Sand filters are a close second for pool owners who want maximum simplicity. DE filters are the best option for water clarity but require more maintenance.
How do I know what size pool filter I need?
Size your filter based on your pool volume and pump flow rate (GPM). Your filter should be rated to handle your pump's output and complete a full turnover of your pool's water volume within 8 hours. When in doubt, go with the next size up — an oversized filter runs at lower pressure and lasts longer than one that's undersized.
What brands of pool filters does EZ Pools carry?
EZ Pools carries pool filters from Hayward, Pentair, Jandy, and Waterway, including complete filter systems, replacement cartridge elements, filter media, and multiport valves.
Where can I find replacement parts for my pool filter?
EZ Pools carries replacement filter cartridges, multiport valves, filter media (sand, DE, glass), and other pool filter parts. You can also visit our Pool Filter Parts collection for o-rings, drain caps, manifolds, and other wear items.
Does EZ Pools ship pool filters quickly?
Yes. EZ Pools fulfills orders from warehouses in New Jersey, Colorado, and Jacksonville, Florida, enabling fast shipping to most of the continental US. Many orders placed before 2 PM ET ship the same day.
