Cartridge filters are one of the simplest ways to keep an above-ground pool clean without dealing with filter sand, backwashing or a multiport valve.
But choosing the right one isn't as simple as buying the pump with the biggest GPH number.
Some cartridge systems are designed for small soft-sided pools. Others are capable of circulating much larger family-sized pools, while premium systems from brands such as Hayward and Pentair use significantly larger cartridges and plumbing.
For this guide, we've focused on the models we'd actually consider for different above-ground pool sizes rather than simply repeating each manufacturer's maximum pool rating.
Our main picks range from the compact Intex C1000 through to the much larger Hayward XStream, with the Pentair Clean & Clear 200 included for owners building a more substantial pump-and-filter setup.
Quick Picks
These aren't ranked simply by power. A C2500 isn't automatically better than a C1000 if you're filtering a small pool, and a Hayward XStream would be unnecessary for many compact above-ground setups. The better choice is the system that gives your pool comfortable circulation without creating unnecessary cost, plumbing changes or maintenance.
Why Are Three of Our Picks Intex?
This is worth addressing directly because three Intex pumps in one roundup can otherwise look repetitive.
The reason is simple: the market for complete cartridge filter-and-pump systems is surprisingly limited.
We looked at alternatives from several manufacturers, but we don't think replacing a stronger product purely to create more brand variety helps the reader.
The C1000, C1500 and C2500 also aren't three versions of essentially the same recommendation. They form a useful size ladder.
The C1000 suits genuinely smaller pools. The C1500 gives medium-sized pools more circulation headroom. The C2500 is the model we'd move to for larger family-sized above-ground pools while still keeping the simplicity of cartridge filtration.
They also benefit from a well-established replacement-cartridge and parts ecosystem.
So rather than forcing a weaker product into the list for variety, we'd rather recommend the system that makes the most sense for each pool size.
How We Chose These Cartridge Filters
We looked beyond the headline pump-flow number.
Where a manufacturer publishes both pump flow and system flow, we put considerably more weight on the system-flow figure because it gives a better indication of circulation once the pump is operating as part of the filtration system.
We also considered cartridge size, plumbing connections, ease of cleaning, replacement-filter availability, timers, parts support and whether the system actually makes sense for the pool sizes people are likely to pair it with.
We also deliberately use more conservative pool-sizing recommendations than some manufacturer maximums.
For Above Ground Splash, we'd generally prefer enough circulation capacity for a theoretical turnover within six hours at most, with additional headroom where practical.
Intex C2500 — Best Overall Complete System
The Intex C2500 is our best overall cartridge filter pump for the type of larger family-sized above-ground pool where the smaller C-series pumps start to become limiting.
Its headline pump capacity is 2,500 GPH, but the figure we'd pay more attention to is its approximately 1,900 GPH system flow.
That's a substantial step up from the C1500.
For a typical round above-ground pool around 16–18 ft, the C2500 is generally where we'd start if you want to remain with cartridge filtration.
It uses an Intex Type B cartridge and gives you considerably more circulation while retaining the straightforward maintenance that attracts people to cartridge systems in the first place.
You remove the cartridge, rinse it when required and replace it once it is no longer cleaning effectively.
There's no filter sand to buy and no backwash cycle to operate.
The C2500 also makes more sense to us than trying to stretch a C1500 toward the upper end of its published pool range.
We'd rather have additional circulation capacity available than run a smaller filter pump close to its limit throughout the season.
Best for: Larger typical above-ground pools, particularly around the 16–18 ft range, where you want a complete cartridge pump-and-filter system.
Skip it if: Your pool is genuinely small, or you're reaching the point where a larger sand filter or premium cartridge system would be a better long-term fit.

Intex C1000 — Best for Small Pools
For a genuinely small above-ground pool, buying a much larger filtration system isn't automatically an upgrade.
That's where the Intex C1000 makes sense.
The pump is rated at 1,000 GPH, with approximately 750 GPH of system flow, and uses the widely available Intex Type A cartridge. It also works with the smaller 1.25-inch hose connections commonly found on compact above-ground pools.
Our recommendation is more conservative than simply pushing it toward the largest pool a retailer or manufacturer may list.
For a typical small round pool up to around 10–12 ft, the C1000 can be a very sensible fit where its system flow provides comfortable turnover.
It's compact, simple and inexpensive to maintain.
What we wouldn't do is choose it for a larger pool simply because it's cheaper than the C1500.
Once you're moving toward the 14–15 ft range, we'd rather have more circulation capacity.
Best for: Small pools where 750 GPH of system flow gives comfortable turnover.
Skip it if: You're already around 14–15 ft or expect to upgrade to a larger pool.
See our full Intex 1000 GPH Cartridge Filter Pump review for more detail.
Intex C1500 — Best for Medium Pools
The Intex C1500 fills the gap between the small C1000 and the higher-capacity C2500 very well.
Its pump is advertised at 1,500 GPH, while the complete filtration system is rated at 1,180 GPH. Intex also includes a built-in timer, HydroAeration and a Type A cartridge.
For us, the C1500 makes the most sense around the 14–15 ft pool range, depending on wall height and actual water volume.
That's considerably more conservative than Intex's published maximum pool capacity, but it gives you circulation headroom for the real conditions a pool experiences.
Cartridges become dirty. Flow reduces. Pools get busy. Wind introduces pollen, grass and debris. Sometimes you're trying to recover cloudy water rather than simply maintain an already-perfect pool.
We'd rather size for those conditions than for an ideal theoretical maximum.
One useful ownership advantage is that the C1500 uses the same common Type A cartridge family as the C1000.
Best for: Medium-sized above-ground pools where the C1000 is beginning to look undersized but the C2500 isn't yet necessary.
Skip it if: You're around 18 ft, where we'd rather have the C2500's additional circulation capacity.

Hayward XStream 150 — Best Premium Complete System
The Hayward XStream 150 is a different class of cartridge system from the compact Intex pumps.
Instead of a small integrated cartridge pump, the XStream combines a 150 sq. ft. cartridge filter with Hayward's 1.5 HP PowerFlo Matrix pump in the W3CC15093S system. Hayward continues to list that combination in its current above-ground filtration range.
That much larger cartridge area is the reason we'd consider it for a substantially larger above-ground pool.
More filter surface area means more room to hold dirt before the cartridge becomes heavily restricted, which can translate into longer periods between cleanings compared with compact cartridge pumps.
For typical larger round pools in roughly the 21–27 ft range, this is where the XStream begins to make much more sense.
It's also a more substantial piece of equipment physically and financially.
If you've got a 12 ft or 15 ft soft-sided pool, we'd have little reason to spend this much or install a filtration system of this size.
But for someone who wants to stick with cartridge filtration on a larger above-ground pool, the XStream is one of the strongest complete systems we've found.
Best for: Larger above-ground pools where you want significantly more cartridge area and a matched pump/filter setup.
Skip it if: You have a smaller pool or want the lower upfront cost and simpler plumbing of an Intex C-series pump.

Pentair Clean & Clear 200 — Best Premium Filter-Only Option
The Pentair Clean & Clear 200 is the outlier in this roundup because it does not include a pump.
That's deliberate.
There aren't many complete cartridge systems above the Hayward XStream that we'd confidently recommend for a normal above-ground pool. For owners building a more substantial custom filtration setup, it can make more sense to choose the filter and pump separately.
The Clean & Clear 200 provides 200 sq. ft. of cartridge area, uses 2-inch plumbing and is listed by Pentair with a flow rating up to 150 GPM. Pentair's current line also includes a clamp-ring design for cartridge access and its High Flow manual air-relief system.
That is far more filter than the average small above-ground pool needs.
We'd consider it where you're deliberately building a high-capacity filtration system and want the larger cartridge area.
The important part is that the separate pump still needs to be matched correctly to the filter and plumbing.
We would not simply buy a large pump because the Pentair filter can accept a high maximum flow.
Best for: Larger or custom above-ground filtration systems where you specifically want a premium filter and separate pump.
Skip it if: You want a simple all-in-one pump/filter package or have a typical small-to-medium above-ground pool.
Also Consider: Bestway 2500 GPH Cartridge Filter Pump
The Bestway 2500 GPH Filter Pump is another legitimate option, particularly if you already own a Bestway or Coleman pool.
Bestway currently lists the system with a 2,500 GPH pump rating, Type IV-B cartridge, a timer that can run for up to 10 hours and compatibility with 1.5-inch threaded valves or 1.25-inch connections using the included adapters. Bestway gives it a broad 300–16,400 gallon manufacturer pool range.
We wouldn't use that upper gallon figure as our own sizing recommendation.
The main reason it sits in Also Consider rather than replacing the C2500 in our main picks is that Bestway publishes the pump-flow figure but doesn't give us the same separate system-flow figure that makes the Intex C-series easier to evaluate conservatively.
That doesn't make the Bestway a poor system.
It simply means we're more comfortable putting the C2500 ahead when choosing one overall cartridge pump for a larger typical above-ground pool.
Another point worth knowing is that you don't necessarily need a Bestway pump just because you own a Bestway or Coleman pool.
Many above-ground systems can be adapted between brands when the hose sizes and fittings are compatible, although we'd always check the exact connections before buying.
What Size Cartridge Filter Do You Actually Need?
These are starting points rather than universal limits. Wall height can dramatically change the number of gallons in two pools with the same diameter.
That's why we'd calculate the actual water volume before buying. Our Pool Volume Calculator for Above-Ground Pools will give you a much better starting point than diameter alone.
We generally prefer a theoretical turnover within six hours at most, and preferably less where practical. Real-world flow can also decline as a cartridge collects dirt, so we don't like sizing a filter pump right at the edge of its published capacity.
Why We Don't Simply Use the Manufacturer's Maximum Pool Size
Manufacturer gallon ratings are useful, but they aren't where we'd stop the calculation.
A filter pump can technically circulate a pool while still taking longer to turn over the complete water volume than we'd prefer.
That matters when conditions aren't ideal.
A dirty cartridge creates more resistance. Heavy swimmer use increases the filtration load. Wind introduces pollen, grass and debris. And when you're trying to recover cloudy water, having extra circulation capacity is much more useful than having a pump that was sized right at its theoretical limit.
That's why our pool-size recommendations are often lower than the maximum number printed on the box.
We'd rather give the filter some breathing room.
Cartridge Filter vs Sand Filter: Which Is Better?
Neither system is automatically better.
A cartridge filter avoids backwashing. When the filter becomes dirty, you open the housing, remove the cartridge and rinse it.
That also means you don't routinely discharge pool water during a backwash cycle.
The trade-off is that cartridge maintenance is hands-on. You physically remove and clean the filter, and cartridges eventually need replacement.
A sand filter keeps its media inside the tank and is normally cleaned by turning the multiport valve to Backwash and Rinse.
For some owners, that's much easier.
As pools get larger or debris loads become heavier, sand filtration can also become increasingly attractive simply because routine filter cleaning doesn't involve removing a large dirty cartridge.
If you're still deciding which filtration type suits your pool best, our Sand Filter vs Cartridge Filter for Above-Ground Pools guide compares maintenance, water use, filtration, sizing and long-term ownership in more detail.
If you've already decided you'd rather go with sand, see our Best Sand Filters for Above-Ground Pools picks.
Don't Forget About Replacement Cartridges
The purchase price of the pump isn't the only thing that matters with cartridge filtration.
You also need to be able to find the correct replacement cartridge easily.
The C1000 and C1500 use Intex's widely available Type A cartridge, while the C2500 steps up to the larger Type B cartridge.
If you own a C1000 or C1500, our Intex Type A Pool Filter Cartridge review looks specifically at replacement filters for those systems. C2500 owners can also see our Intex Type B Pool Filter Cartridge review for the larger cartridge used by that pump.
Regular rinsing can extend the useful life of a cartridge, and a proper filter-cleaning tool can make getting dirt from between the pleats easier. We've also covered the Aquatix Pro Pool Filter Cartridge Cleaner if you want an alternative to simply spraying the cartridge with a standard hose nozzle.
Replace the cartridge when it is damaged, heavily worn or no longer returns to good flow after proper cleaning rather than throwing it away solely because a fixed number of weeks has passed.
Our Final Recommendation
For most above-ground pool owners who want a complete cartridge pump-and-filter system, the Intex C2500 is our best overall pick.
It offers considerably more circulation capacity than the C1000 and C1500 without forcing you into a premium professional-style filtration setup.
But we wouldn't buy it for every pool.
For a genuinely small pool, the C1000 is simpler and perfectly sensible. Around 14–15 ft, the C1500 is the better fit. For larger pools where you want much more cartridge area and a heavier-duty complete system, the Hayward XStream is the model we'd move toward.
The Pentair Clean & Clear 200 is different again. We'd reserve that for someone deliberately building a larger system with a separate correctly sized pump.
And while the Bestway 2500 GPH system remains worth considering, particularly for Bestway and Coleman owners, we don't see enough reason to put it ahead of the C2500 as our main recommendation.
The most important thing is not buying the largest filter on this page.
It's choosing the one that gives your pool comfortable circulation without creating unnecessary cost or complexity.
Frequently Asked Questions
What is the best cartridge filter for an above-ground pool?
For many larger typical above-ground pools, our best overall complete cartridge system is the Intex C2500. Smaller pools may be better suited to the C1000 or C1500, while larger premium setups can justify a Hayward XStream.
What size cartridge filter do I need for my above-ground pool?
Start with the actual water volume rather than pool diameter alone. We prefer enough system flow to provide a theoretical turnover within six hours at most, with additional circulation headroom where practical.
Is the Intex C1000 big enough for a 15 ft pool?
We'd generally prefer the C1500 as pools move toward the 14–15 ft range. The C1000 makes more sense for smaller pools where its approximately 750 GPH system flow already provides comfortable circulation.
Should I buy the Intex C1500 or C2500?
For a typical round above-ground pool around 14–15 ft, we'd generally choose the C1500. Around 16–18 ft, we'd rather have the additional circulation capacity of the C2500.
Is a cartridge filter better than a sand filter?
Not universally. Cartridge filters avoid backwashing but require the cartridge to be removed and rinsed. Sand filters keep the media inside the tank and are cleaned through a backwash cycle. The better choice depends on pool size and which maintenance routine you prefer.
Can I use an Intex cartridge filter pump on a Bestway or Coleman pool?
Often, yes, provided the hose sizes and fittings are compatible or can be adapted correctly. Don't assume every model is a direct fit, though. Check the pool's inlet and outlet connections before buying.
Is the Hayward XStream worth it for an above-ground pool?
It can be for a larger above-ground pool where the much greater cartridge area and heavier-duty pump/filter system are useful. For a small or medium pool, the extra cost and capacity are usually unnecessary.
Does the Pentair Clean & Clear 200 include a pump?
No. The Clean & Clear 200 is a standalone cartridge filter. It needs to be paired with a separate pump that is properly matched to the filter, plumbing and required system flow.
