The best pool filter depends on your pump type, pool size, and preference for replaceable cartridges or a sand filtration system. For compatible above-ground pumps, MUDEREK offers a 12-pack, INTEX is a straightforward choice for specified INTEX pumps, and Swimara provides a six-pack with listed model compatibility. Funsicle is a simple two-pack option, while AQUASTRONG is a complete sand filter pump for buyers seeking a different filtration setup. Always check the filter type and dimensions before ordering.
| Product | Best for | Type |
|---|---|---|
| MUDEREK 12 Pack | Keeping replacement cartridges on hand | Type A/C/III cartridge |
| INTEX Type A Two Pack | Specified INTEX filter pumps | Type A cartridge |
| Swimara Six-Pack | Listed compatible pump models | Type A/C cartridge |
| AQUASTRONG Sand Filter Pump | Above-ground pools up to 13,000 gallons | Sand filter pump |
| Funsicle Type A/C Two Pack | Buyers seeking a basic replacement pair | Type A/C cartridge |
MUDEREK 12-Pack Universal Pool Filters
Best for: Pool owners who want a larger supply of replacement cartridges for a compatible above-ground pool pump. This 12-pack is listed for Type A, C, and III filters and is designed to capture debris such as sand, hair, leaves, and sediment.
The product description gives dimensions of 8 by 4.2 inches with a 1.9-inch center hole. It describes polyester filter media, pleated construction, and a plastic mesh support structure. The manufacturer also says the cartridge is reusable by replacing the filter paper in the middle.
Why it stands out: The pack size and stated reusable design may suit buyers seeking fewer frequent cartridge purchases. Check before buying: Confirm the old cartridge’s dimensions and type; “universal” does not remove the need to verify fit.
INTEX Type A Filter Cartridge, Two Pack
Best for: Owners of the INTEX pump models listed by the manufacturer: 28603EG, 28637EG, and 28635EG. The cartridge uses Dacron paper and is described as easy to clean, making it a direct option for routine cartridge maintenance on those compatible pumps.
This two-pack is a smaller supply than the MUDEREK and Swimara multipacks. INTEX recommends replacing cartridges every two weeks for maximum efficiency and results, although actual maintenance needs can depend on pool use and water conditions.
Why it stands out: The manufacturer names specific pump models, which makes compatibility easier to check. Check before buying: It is identified as Type A, so avoid choosing it solely because another cartridge looks similar; confirm your pump requires this type.
Swimara Pro Series Type A/C Six-Pack
Best for: Buyers whose pump matches the listed INTEX or Flowclear models and who prefer a six-cartridge supply. Swimara lists compatibility with INTEX 28603EG/C530, 28637EG/C1000, and 28635EG/C1500, as well as Flowclear 58388E pumps using Type III-A/C cartridges.
The cartridges measure 8 by 4.25 inches and are listed as replacements for several part numbers, including 29000W, 29000E, 59900E, and 58012E. The product description identifies trilobal polyester media, pleats, and an internal support core. It says the pleats help maintain water paths during filtration and routine hose rinsing.
Why it stands out: The stated dimensions, replacement numbers, and pump models support a detailed fit check. Check before buying: Compare both the cartridge size and your pump’s required type with the listing.
AQUASTRONG 14-Inch Sand Filter Pump
Best for: Above-ground pool owners who want a sand filter pump rather than a replacement cartridge. The product is specified for pools up to 13,000 gallons, with a 3000 GPH pump flow rate and a stated system flow rate of 2400 GPH.
Its six-way valve includes Filter, Waste, Closed, Backwash, Recirculate, and Rinse settings. A programmable timer offers nine settings from two to 24 hours. These features make it a different kind of purchase from the cartridge packs: it is a pump-and-filter system, not a drop-in cartridge replacement.
Why it stands out: It offers multiple operating modes and timed filtration for buyers considering a sand setup. Check before buying: Confirm pool capacity and setup needs. The instructions say to stop the pump before changing the valve position.
Funsicle Type A/C Filter Cartridge Two-Pack
Best for: Pool owners who have verified that their pump takes a Type A/C cartridge and need a two-pack. Funsicle describes this as a replacement cartridge set with more pleats for filtration.
Why it stands out: It provides a simple small-pack option for buyers who do not need a larger multipack. Its listed product information is brief, however, and does not provide dimensions or specific pump model numbers.
Check before buying: Verify cartridge dimensions and pump compatibility with the manufacturer or your existing cartridge. The available product details do not establish fit for any particular pump model.
Buying Guide: How to Choose a Pool Filter
Does your pump use a cartridge or sand filter?
Start by identifying your current filtration system. Cartridge products in this guide are replacement elements for compatible cartridge pumps. AQUASTRONG is a sand filter pump, so it is not interchangeable with a Type A or Type C cartridge. Match the product category to your pool’s existing equipment unless you intend to change systems.
Which cartridge type and size do you need?
Check the old cartridge for its type, dimensions, and any replacement number. Type A, C, and III labels can overlap in product listings, but they do not guarantee that every cartridge fits every pump. Compare measurements and model numbers, particularly when a listing has limited compatibility details.
Is a two-pack or multipack a better fit?
A two-pack may work for occasional replacement or a smaller supply. Six- and 12-packs provide more cartridges at once, but only make sense if the product matches your pump. Consider the manufacturer’s maintenance guidance and your pool’s cleaning routine when choosing how many to keep available.
What features should you compare?
For cartridges, compare stated media, pleat design, support structure, cleanability, and whether the product claims a reusable component. For a sand filter pump, compare pool capacity, flow specifications, valve settings, and timer functions. Treat stated features as product specifications, not a substitute for confirming fit and following operating instructions.
Pool Filter FAQ
How often should a pool filter cartridge be replaced?
INTEX recommends replacing its Type A cartridge every two weeks for maximum efficiency and results. Follow the guidance for your specific pump and check the cartridge condition during routine cleaning.
Can a Type A cartridge replace a Type C cartridge?
Not automatically. Buy a cartridge only when its type and dimensions match your pump requirements. Some listings cover multiple types, but compatibility should be confirmed for the specific equipment.
Are cartridge filters and sand filter pumps the same?
No. A cartridge is a replaceable filter element used in a cartridge pump. A sand filter pump is a separate filtration setup with its own filter vessel and operating controls.
What should I check before ordering a replacement filter?
Check the pump model, cartridge type, dimensions, center-hole size where provided, and replacement part number. When a listing does not give model details or measurements, verify compatibility before purchasing.
