The right pool filter depends on your equipment: cartridge replacements suit compatible Pentair or SwimClear systems, while Intex sand filter pumps are designed for specified above-ground pools. The POOLPURE and Swimara cartridges are best for Pentair CCP420-style filters, Cryspool is best for compatible SwimClear models, and the two Intex pumps serve different pool capacities. Check your existing system’s model and cartridge dimensions before choosing a replacement.

POOLPURE CCP420 Pool Filter 4-Pack
This four-pack is best for pool owners seeking cartridge replacements compatible with Pentair CCP420-style filtration systems. Each cartridge is listed with a 105-square-foot filtration area, a 26-inch length, a 7-inch outside diameter, and 3-inch openings at both ends. The filter material is trilobal filtration fabric.
The listing also names Waterway Crystal Water 425 and several replacement part numbers among its compatible models. It is selected for its clearly stated dimensions and broad compatibility references. Confirm your original cartridge’s measurements and model before ordering; the manufacturer notes that its brand and part numbers are used for reference and that POOLPURE is an independent brand.
Cryspool 07072 SwimClear Cartridges
Cryspool’s four-cartridge set is best for owners of compatible SwimClear systems, including listed models C4030, C4025, and C4020. Each cartridge measures 25.5 inches long and 7 inches across, with 3-inch top and bottom openings. The listing gives a filtration area of 106 square feet per cartridge, or 424 square feet across the four-piece set.
The cartridges use trilobal fibers, which the listing describes as an advanced filter material. This option is included because its model references and dimensions distinguish it from CCP420 replacement sets. Avoid choosing it based only on the name of your pool or filter brand: verify the exact model and measurements, since the seller identifies CRYSPOOL as an independent brand.
Swimara Essential Series CCP420 Cartridges
This four-pack is best for buyers replacing cartridges in a listed Pentair CCP420 or Waterway Crystal Water 425 setup. It provides 105 square feet per cartridge and 420 square feet total. Listed dimensions are 7 inches in outside diameter, 26 inches long, and 3 inches at the open ends.
The construction includes round-fiber media, molded polyurethane end caps, a polypropylene core, and retaining bands. These details make it a useful comparison for buyers who want the construction materials specified alongside fit information. Check your existing filter’s dimensions before purchase; the listing specifically advises verifying size, and compatibility should not be assumed from a similar model name alone.
Intex Krystal Clear SX1500 Sand Filter Pump
The SX1500 is best for owners of compatible Intex above-ground pools up to 8,400 gallons who want a sand filter pump rather than a replacement cartridge. It has a six-function valve for filtering, backwashing, rinsing, recirculating, draining, and closing the system. A built-in timer offers preset cycles from two to 12 hours.
The listing describes installation as connecting hoses and plugging in, with partial assembly required. Two 1.5-inch connector hoses are included. Choose this model if your pool falls within its stated capacity range; it is not presented as a cartridge replacement for Pentair or SwimClear filter systems.
Intex Krystal Clear SX2800 Sand Filter Pump
The SX2800 is best for compatible Intex above-ground pools up to 17,200 gallons. Its listed flow rate is 2,800 gallons per hour, and it has the same six valve functions and two-to-12-hour timer range as the SX1500. The listing includes two 1.5-inch connector hoses and notes that partial assembly is required.
Compared with the SX1500, this model is specified for a larger pool capacity and has a higher stated flow rate. Select it if your pool fits the listed range and you need a sand filter pump. Avoid assuming that higher flow makes it suitable for every pool: the product information only specifies Intex above-ground pools up to 17,200 gallons.
Buying Guide: How To Choose A Pool Filter
Do you need a cartridge or a complete pump?
Choose a cartridge when your existing filtration system is working and you need a replacement element. The POOLPURE and Swimara options reference CCP420-compatible systems, while Cryspool lists SwimClear models. Choose an Intex sand filter pump if you are selecting a pump-and-filter unit for a compatible above-ground pool. These product types are not interchangeable.
How can you check cartridge compatibility?
Use the model number on your current filter or cartridge, then compare it with the seller’s compatibility list. Check length, outside diameter, and opening size as well. The three cartridge products have similar dimensions, but their listed system references differ. A similar size alone does not confirm a fit.
How should you compare filtration area and pump capacity?
For cartridge sets, compare the area per cartridge as well as the total area across the pack. The POOLPURE and Swimara listings specify 105 square feet per cartridge; Cryspool specifies 106. For the Intex pumps, compare the stated pool capacity: up to 8,400 gallons for the SX1500 and up to 17,200 gallons for the SX2800.
Frequently Asked Questions

No. A cartridge is a replacement filter element for a compatible filtration system. A sand filter pump is a pump-and-filter unit, such as the two Intex models listed here.
Will a CCP420 cartridge fit every Pentair filter?
No. The listings name specific compatible models and dimensions. Confirm your filter’s exact model and cartridge size before ordering.
Which Intex pump is intended for a larger pool?
The SX2800 is listed for Intex above-ground pools up to 17,200 gallons. The SX1500 is listed for pools up to 8,400 gallons.
Do the cartridge packs include four filters?
