Cartridge pool filters come in dozens of sizes and cross-compatible part numbers, and picking the wrong one means weak circulation, cloudy water, and wasted money on replacements. The Pentair EC-160301 Clean & Clear Plus 420 stands out as the best overall pick thanks to its genuine OEM fit, four-cartridge design, and 420 square feet of filtration area that suits most in-ground pools. For value hunters, the POOLPURE CCP420 four-pack delivers comparable filtration area at a fraction of the cost, while the INTEX 29002E Type A two-pack is the clear choice for small above-ground setups. The main tradeoff in this category is OEM quality and longevity versus aftermarket affordability, plus matching square footage to your filter housing.

Key Takeaways
- OEM Pentair filtration (the EC-160301) sets the benchmark for fit and longevity, but well-made aftermarket replacements like the POOLPURE CCP420 four-pack close most of the gap for far less money.
- Square footage is the single biggest spec: 100–150 sq ft cartridges suit spas and small above-ground pools, while 420–520 sq ft models handle full-size in-ground pools with less frequent cleaning.
- The Intex Type A/C options and the INTEX 29002E two-pack are an entirely different product class — cheap, small, frequently replaced cartridges for low-flow cartridge pumps, not a budget alternative to big filters.
- Multi-packs (four-packs for CCP420, KGC C3030, and POOLPURE CCP520) consistently offer the lowest cost per cartridge and make sense if you clean rather than discard cartridges between cleanings.
- Reinforced cores, antimicrobial pleats, and precise end-cap fit are what separate durable aftermarket cartridges from ones that collapse or bypass water after a single season — cheaper pleat counts fail first.

More Details on Our Top Picks
Essential Series for Pentair CCP420 Pool Filter Cartridges 420 sq ft
This 4-pack targets one specific job: replacing the cartridges in a Pentair CCP420 tank without overspending on media you may not need. The 3 oz/sq yd round-fiber pleated media is the lighter of the two Swimara options here, and that’s the point — for a typical residential pool with ordinary dirt loads, the heavier Ultra Series construction is money left on the table. Compared with the POOLPURE CCP420 4-Pack, the specs align on size and NSF/ANSI 50 certification, so the choice comes down to media weight rather than fit. The molded PU end caps and pleat bands translate to fewer seating leaks and even water distribution across the pleat pack, which means slower pressure rise between cleanings.
The tradeoff: round-fiber media releases fine particles sooner than trilobal fabric under heavy pollen, so owners in dusty climates will rinse more often.
Pros:- Full 4-pack covers a complete CCP420 tank swap at once
- NSF/ANSI 50 certified media for material safety
- PU end caps and pleat bands keep cartridges seated and pleats evenly spaced
- Garden-hose cleaning with a simple 10 PSI rinse trigger
Cons:- Lighter 3 oz/sq yd media holds less fine debris than trilobal options
- Round-fiber construction means more frequent rinsing in high-debris yards
Best for: Budget-conscious owners of Pentair CCP420 or Waterway Crystal Water 425 tanks who want a full replacement set for normal seasonal debris
Not ideal for: Pools battling heavy pollen, silt, or fine dust — the lighter round-fiber media loads up faster than trilobal alternatives
- Fits:Pentair CCP420 (#160301), Waterway Crystal Water 425
- Replaces:PCC105, R173576, 178584, 817-0106, C-7471, FC-1977
- Pack size:4 cartridges (105 sq ft each, 420 sq ft total)
- Dimensions:7 in. OD x 26 in. L, 3 in. open ends
- Media:3 oz/sq yd round-fiber pleated
- End caps / core:Molded PU end caps, reinforced PP core
- Certification:NSF/ANSI 50
Our verdict“The sensible default for CCP420 owners who want dependable everyday filtration at a full-set price.”
Ultra Series for Pentair CCP420 Pool Filter Cartridges 420 sq ft
Think of this as the Essential Series’ heavier sibling. Same CCP420 fit, same four-cartridge format, but the media jumps to 5 oz/sq yd trilobal fabric rated to 10 microns — a real difference for pools that chew through cartridges. Where the Essential version handles ordinary dirt, this one is built for high-use pools, heavy pollen seasons, and fine-debris conditions, because trilobal fibers expose more capture surface per pleat and the heavier cloth resists compacting when loaded. Compared with the Pentair EC-160301 OEM cartridge, buyers here are choosing aftermarket construction with a substantially heavier media spec rather than factory original branding.
The reinforced PP core matters more at this weight: a heavier pleat pack puts more stress on the core during high-flow operation, and the strengthened build keeps pleats from collapsing. The honest tradeoff is cost per set and cleaning effort — denser media rinses slower, and the buyer pays a premium for capacity they won’t use on a lightly used pool.
Pros:- 5 oz/sq yd trilobal media captures particles down to 10 microns
- Heavier cloth holds more dirt before pressure rises, stretching cleaning intervals
- Reinforced core and pleat bands stabilize the heavier pleat pack under high flow
- Fits the same CCP420 platform as the Essential Series for easy upgrading
Cons:- Premium media costs more per set than round-fiber alternatives
- Denser pleats take longer to rinse clean between cycles
Best for: Owners of busy in-ground pools, heavy-bather-load households, or properties with persistent pollen and fine dust
Not ideal for: Occasionally used or screened-in pools where the lighter Essential Series does the same job for less
- Fits:Pentair CCP420 (#160301), Waterway Crystal Water 425
- Replaces:PCC105, R173576, 178584, 817-0106, C-7471, FC-1977
- Pack size:4 cartridges (105 sq ft each, 420 sq ft total)
- Dimensions:7 in. OD x 26 in. L, 3 in. open ends
- Media:5 oz/sq yd heavy-duty trilobal
- Certification:NSF/ANSI 50
Our verdict“The upgrade pick for CCP420 owners whose pools face serious debris loads and who want longer intervals between cleanings.”
POOLPURE CC100 Pool Filter Replaces Pentair CCRP100, R173215, PAP100
Not every pool owner needs a four-pack. This single 100 sq ft cartridge fits the Pentair Clean and Clear 100, Posi-Clear PCRP100, Predator 100, and their Unicel and Filbur equivalents, making it the practical choice when one element is due and the others still have life left. The trilobal fabric with a claimed 3x adsorption surface and dirt-locking pleat design means rinsing releases debris instead of smearing it deeper — a real maintenance advantage over basic spun cartridges like the INTEX Type A, which is a disposable paper element for a completely different class of equipment. Build quality leans durable: 4 oz polyester media, reinforced ABS end caps, and an integrated core.
The catch is capacity. At 100 sq ft, this cartridge suits smaller Clean and Clear tanks; owners of larger systems should look at the POOLPURE CC150 or the CCP420 four-packs instead.
Pros:- Trilobal fabric with dirt-locking pleats rinses clean with minimal effort
- 50-micron filtration layer captures hair, sand, dust, and fine debris
- 4 oz media and reinforced ABS end caps extend service life over standard cartridges
- NSF/ANSI 50 certified by IAPMO for material safety
Cons:- Single cartridge only — poor value if all elements need replacing at once
- Limited 100 sq ft area forces frequent cleaning on busy pools
Best for: Owners of Clean and Clear 100 / Predator 100 tanks replacing one worn cartridge without buying a full set
Not ideal for: Large or high-use pools — 100 sq ft of media clogs quickly under heavy bather and debris loads
- Dimensions:23 5/8 in. L x 10 1/16 in. OD
- Openings:6 in. top and bottom
- Filtration area:100 sq. ft.
- Media:4 oz trilobal polyester
- Compatible models:Pentair CCRP100, R173215, PAP100, Unicel C-9410, Filbur FC-0686
- Pack size:1 cartridge
- Certification:NSF/ANSI 50
Our verdict“A low-commitment, high-quality swap for small Clean and Clear systems that need one cartridge now, not four.”
POOLPURE CC150 Pool Filter Replaces Pentair CC150, CCRP150, R173216, PAP150
This is the CC100’s bigger sibling — same POOLPURE construction, same trilobal fabric and dirt-locking pleats, but stretched to 150 sq ft of media and a 31 1/8-inch length. That extra 50 percent of filtration area translates directly into longer runs between rinses and lower pressure creep, which is why anyone with a Clean and Clear 150, Ultra-C4, or PP-C4 tank should pay the modest step up rather than settling for the shorter cartridge. Against the Swimara Essential 4-Pack, the roles split cleanly: that set serves large four-cartridge CCP420 tanks, while this single element serves the widely installed two-cartridge 150-class systems. The reinforced ABS end caps and integrated core matter at this length, since longer cartridges flex more under flow.
The limitation is fit specificity — at over 31 inches it simply will not seat in a 100-series tank, and buyers must measure before ordering.
Pros:- 150 sq ft of media extends time between cleanings versus 100 sq ft cartridges
- Trilobal fabric and dirt-locking design release debris easily when rinsed
- Heavy-duty 4 oz media with reinforced ABS caps rated for longer service life
- Broad cross-compatibility with Unicel C-9415, Filbur FC-0687, and Aladdin 25005
Cons:- Single-pack pricing makes a full two-cartridge swap more expensive
- Exact 31 1/8 in. length leaves no tolerance for mismatched tanks
Best for: Owners of Pentair Clean and Clear 150 / Posi-Clear 150 systems wanting longer cleaning intervals from one cartridge
Not ideal for: Anyone with a 100-series or CCP420 tank — the length and diameter only match 150-class housings
- Dimensions:31 1/8 in. L x 10 1/16 in. OD
- Openings:6 in. top and bottom
- Filtration area:150 sq. ft.
- Media:4 oz trilobal polyester
- Compatible models:Pentair CC150, CCRP150, R173216, PAP150, Unicel C-9415, Filbur FC-0687
- Pack size:1 cartridge
- Certification:NSF/ANSI 50
Our verdict“The right-sized upgrade for 150-class Clean and Clear owners who want durability without buying more cartridge than their tank holds.”
XtremepowerUS Swimming Pool Cartridge Filter System, 175 SF, 2-Inch Ports
Everything else in this lineup is a replacement element; this is the whole filtration system — tank, cartridge, plumbing ports, gauge, and relief valve. That changes who it’s for entirely. With 2-inch ports and a 150 gpm flow rate, it handles pools up to 52,800 gallons on an 8-hour turnover, comfortably out-sizing cartridge swaps like the KGC C3030 for Hayward SwimClear, which assumes you already own a big tank. The 10-15 micron capture rating puts its clarity performance in the same band as premium trilobal cartridges, and the pressure gauge plus automatic relief valve at 150 kPa gives first-time equipment buyers a safety net that bare cartridges can’t offer.
Two honest drawbacks: it’s a budget-tier system, so the tank build won’t match a Pentair Clean and Clear Plus shell, and replacement cartridges are tied to a specific XtremepowerUS SKU (75214) rather than the widely stocked industry cross-references.
Pros:- Complete system includes tank, cartridge, 2-inch ports, gauge, and relief valve
- 150 gpm flow rate covers pools up to 52,800 gallons on an 8-hour cycle
- Captures particles down to 10-15 microns for fine-debris clarity
- UV- and corrosion-resistant resin construction suits outdoor year-round use
Cons:- Replacement cartridges use a proprietary XtremepowerUS SKU instead of universal cross-references
- Budget-tier tank construction lags premium Pentair or Hayward shells in longevity
Best for: Owners building or replacing an entire filtration setup on a large above-ground or in-ground pool without buying a premium tank
Not ideal for: Anyone who just needs cartridges for an existing Pentair or Hayward tank — this adds hardware they don’t need
- Type:Complete cartridge filter system (tank + cartridge)
- Filtration area:175 sq. ft. cartridge element
- Flow rate:150 gpm
- Ports:2 in. inlet and outlet
- Pool capacity:Up to 26,400 gal @ 4 hrs; 52,800 gal @ 8 hrs
- Safety features:Pressure gauge and automatic relief valve (150 kPa)
- Construction:Weather, UV, and corrosion-proof resin
- Replacement cartridge:SKU 75214 (ASIN B08J1W1T8N)
Our verdict“A one-box filtration solution for buyers upgrading an entire system on a large pool rather than swapping cartridges.”
KGC C3030 Pool Filter Cartridge Replacement for Hayward CX580XRE C580E (4 Pack)
This option stands out for buyers who want a full four-cartridge refresh of a Hayward SwimClear C3030-style tank without paying OEM prices. At 81 sq. ft. per cartridge, it delivers a combined 325 sq. ft. of filtration, and the trilobal fabric catches particles down to 10–15 microns — a finer rating than the POOLPURE CCP520’s 50-micron claim. Compared with the POOLPURE C1200 single-pack, having four cartridges on hand means you can rotate a clean set in while the dirty ones soak, which shortens downtime. The tradeoff is brand track record: KGC lacks the NSF/ANSI 50 certification PoolPure carries, so buyers prioritizing verified material safety may want the CCP520 instead. Also note these are rinse-only cartridges — no backwashing, and forcing it can crack the pleats.
Pros:- Four cartridges cover a full season of rotations for large cartridge tanks
- Trilobal fabric filters down to 10–15 microns for finer clarity
- BPA-free and lead-free construction
- Washable and reusable with simple hose rinsing or filter-cleaner soaks
Cons:- No NSF/ANSI 50 certification unlike PoolPure alternatives
- Third-party brand means fit tolerance is less predictable than OEM Hayward cartridges
- Cannot be backwashed — improper handling can cause permanent cracking
Best for: Budget-conscious owners of large SwimClear C3030/C3025 tanks who want spare cartridges ready for rotation
Not ideal for: Buyers who want certified material safety documentation or a trusted-name guarantee on fit and finish
- Compatible Models:Hayward CX580XRE, C580E, SwimClear C3020/C3025/C3030, Unicel C-7483, Filbur FC-1225, Pleatco PA81
- Filtration Area (each):81 sq. ft.
- Pack Size:4 cartridges
- Dimensions:19 5/8″ L x 7″ OD
- Openings:3″ top / 3″ bottom
- Filter Material:Trilobal filtration fabric (PET)
Our verdict“A sensible bulk buy for SwimClear C3030 owners who value micron rating and quantity over brand-name assurance.”
POOLPURE CCP520 Pool Filter Replaces Pentair Clean and Clear Plus 520 (4 Pack)
With 130 sq. ft. per cartridge and a 520 sq. ft. total across the pack, this is the highest-capacity replacement set in this lineup, built for Pentair’s biggest Clean and Clear Plus tank. Compared with the POOLPURE CCP420, the extra six inches of cartridge length translates directly into longer runs between cleanings — a real outcome for pools with heavy bather loads or leaf exposure. The NSF/ANSI 50 certification and 4 oz. reinforced polyester build put it a step above the KGC C3030 on verified safety and durability. The honest tradeoff: the 50-micron filtration layer is coarser than KGC’s 10–15 micron claim, and these long cartridges are physically awkward to hose off — expect a two-hand, full-hose-rinse cleaning ritual each cycle.
Pros:- Highest per-cartridge capacity in the lineup at 130 sq. ft.
- NSF/ANSI 50 certified materials for long-term water exposure
- Reinforced ABS end caps and integrated core extend service life
- Dirt-locking pleat design releases debris easily during rinsing
Cons:- 32-inch cartridges are cumbersome to handle and clean
- 50-micron rating is coarser than competing trilobal cartridges
- Only fits the largest CCP tanks — compatibility window is narrow
Best for: Owners of large in-ground pools running a Pentair Clean and Clear Plus 520 tank who want fewer cleaning cycles
Not ideal for: Small pools or spas — oversized cartridges waste money and cleaning effort if your tank takes CCP420 or smaller
- Compatible Models:Pentair CCP 520, 160332, 178585, R173578, Aladdin 22505, Pleatco PCC130
- Filtration Area (each):130 sq. ft.
- Pack Size:4 cartridges
- Dimensions:32 1/16″ L x 7″ OD
- Openings:3″ top / 3″ bottom
- Filter Material:Trilobal filtration fabric
- Certification:NSF/ANSI 50 (IAPMO tested)
Our verdict“The right pick if your pool demands maximum dirt-holding capacity and you already run a CCP520 system.”
Pentair EC-160301 Clean & Clear Plus 420 sq. ft. Cartridge Pool Filter
Everything else in this roundup is a refill; this is the entire filtration unit. For someone building a new system or replacing a failing tank, the genuine Pentair EC-160301 pairs a 420 sq. ft. four-cartridge array with plumbing-ready details: 2-inch unions, a 1-1/2-inch winterization drain, and an internal air bleed that prevents air locking — features no replacement cartridge can replicate. Compared with buying a generic tank plus POOLPURE CCP420 refills, the OEM fit and finish here means fewer seal headaches and predictable flow rates. The obvious tradeoff is cost: this is a plumbing project, not a drop-in purchase, and replacement cartridges down the road — like the POOLPURE CCP420 — will be a recurring expense. If your existing tank is sound, skip this and just buy cartridges.
Pros:- Genuine Pentair OEM build with exact factory tolerances
- 2-inch unions support high flow rates for large in-ground pools
- Internal air bleed prevents trapped air and flow loss
- Dedicated 1-1/2″ drain simplifies winterization
Cons:- Substantially more expensive than any cartridge replacement pack
- Requires plumbing work and space for installation
- Future cartridge refills add ongoing cost
Best for: Pool owners installing a new filtration system or replacing a cracked, leaking cartridge tank
Not ideal for: Anyone with a working tank — buying a whole system just to get clean cartridges wastes serious money
- Type:Complete cartridge filter system
- Total Filtration Area:420 sq. ft.
- Cartridges Included:4 polyester filter cartridges
- Port Size:2″ unions
- Drain:1-1/2″ winterization drain
- Brand:Pentair (OEM)
- Air Handling:Internal air bleed
Our verdict“Buy this only when you need the tank itself — for everyone else, cartridges are the smarter spend.”
POOLPURE CCP420 Pool Filter Replaces Pentair Clean and Clear Plus 420 (4 Pack)
This pick makes the most sense for the largest group of Pentair owners: those running the ubiquitous CCP420 tank, the same system the Pentair EC-160301 ships with. Each cartridge offers 105 sq. ft. of trilobal media with the same NSF/ANSI 50 certification and reinforced ABS construction as the larger POOLPURE CCP520 — just six inches shorter and easier to wrangle during cleaning. Compared with the KGC C3030, the certified materials and dirt-locking pleat design give an edge in longevity and rinse-out ease, though the 50-micron rating is coarser. It also fits Waterway Crystal Water 425 systems, broadening its usefulness. The real drawback is capacity ceiling: heavy-debris pools will clog a 105 sq. ft. set noticeably faster than the CCP520’s 130 sq. ft. cartridges, meaning more weekend rinse sessions.
Pros:- Fits the most common Pentair tank plus Waterway Crystal Water 425
- NSF/ANSI 50 certified for material safety
- 26-inch length is easier to handle and rinse than CCP520 cartridges
- Reinforced 4 oz. polyester fabric with strengthened core
Cons:- 50-micron filtration is coarser than some competing trilobal options
- Less dirt capacity than the CCP520 for demanding pools
- Four-pack only — no single-cartridge option for partial replacement
Best for: Owners of mid-size in-ground pools with a CCP420 or Crystal Water 425 tank who want certified cartridges at a fair cost
Not ideal for: Leaf-heavy or heavily used pools that would benefit from the CCP520’s larger capacity
- Compatible Models:Pentair CCP420, 160301, Waterway Crystal Water 425, Filbur FC-6470, Aladdin 20503
- Filtration Area (each):105 sq. ft.
- Pack Size:4 cartridges
- Dimensions:26″ L x 7″ OD
- Openings:3″ top / 3″ bottom
- Filter Material:Trilobal filtration fabric
- Certification:NSF/ANSI 50 (IAPMO tested)
Our verdict“The practical middle ground for CCP420 owners — certified, capable, and priced for regular rotation.”
POOLPURE C1200 Pool Filter Replace Hayward CX1200RE, HAY823C, Pleatco PA120 (1 Pack)
Not everyone needs a four-pack. This single 120 sq. ft. cartridge targets Hayward Star Clear Plus C1200 and similar 125 sq. ft.-class tanks, making it the right-sized purchase for owners replacing one worn element rather than the full set. The 4-inch openings and 8-15/16-inch diameter distinguish it physically from the 7-inch Pentair-style cartridges like the POOLPURE CCP420 — these are wider, stubbier elements for a different tank family. Certification and build quality match PoolPure’s larger packs, including the NSF/ANSI 50 rating and dirt-locking pleats. The tradeoff is simple economics: buying one at a time costs more per cartridge than the KGC C3030 or CCP420 multipacks, and 120 sq. ft. of media clogs faster in debris-heavy pools than the CCP520’s 130 sq. ft. per element. Match your tank, not the deal.
Pros:- Wide-body 120 sq. ft. element fits Hayward’s popular C1200 tank family
- Cross-compatible with Pleatco PA120, Unicel C-8412, and Filbur FC-1293
- NSF/ANSI 50 certified materials
- Right-sized purchase when only one cartridge needs replacing
Cons:- Higher cost per cartridge than any four-pack option
- Single element means no rotation spares on hand
- Lower total capacity than larger systems like the CCP520
Best for: Hayward Star Clear Plus C1200 owners replacing a single spent cartridge instead of the full set
Not ideal for: Buyers doing a full refresh — single-cartridge purchasing costs more per element than multipacks
- Compatible Models:Hayward Star Clear Plus C1200 / CX1200RE, HAY823C, Unicel C-8412, Filbur FC-1293, Pleatco PA120
- Filtration Area:120 sq. ft.
- Pack Size:1 cartridge
- Dimensions:23 1/4″ L x 8 15/16″ OD
- Openings:4″ top / 4″ bottom

- Certification:NSF/ANSI 50 (IAPMO tested)
Our verdict“A precise, certified fix for one tired Hayward C1200 cartridge — just don’t expect multipack value.”
Type A or C Replacement Filter Cartridge for Intex Above Ground Pools (6-Pack)
Replacing a cartridge every two weeks burns through a 2-pack fast, and that’s where this six-pack of Type A/C cartridges earns its spot. Compared with the Intex 29002E two-pack, this Volca Spares set covers a full swim season for most casual pool owners, which means fewer reorders and fewer “why is my water cloudy” surprises when the last cartridge is spent. Compatibility is broad, spanning Intex pump models up to 1500 GPH plus Summer Waves canisters, so mixed-brand households are covered. The tradeoff is material quality: the Dacron media is easy to hose off but thinner than OEM, so heavy debris loads or frequent pool parties will clog it faster than the genuine article. Still, at this quantity, swapping early costs almost nothing.
Pros:- Six cartridges cover roughly three months of two-week replacement cycles
- Broad fit across Intex and Summer Waves pumps up to 1500 GPH
- Easy-to-clean Dacron media simplifies maintenance
- Low per-cartridge cost when bought in bulk
Cons:- Media is thinner than OEM Intex cartridges and clogs faster under heavy debris
- Two-week replacement schedule still applies — these are not long-life filters
Best for: Owners of small Intex or Summer Waves above-ground pools who want a season’s worth of cartridges bought in one order
Not ideal for: Anyone with a large in-ground pool or a Hayward/Pentair system — Type A/C cartridges won’t fit those housings
- Cartridge Type:Type A/C (29000E/59900E)
- Quantity:6 cartridges
- Dimensions:8 x 4.3 x 4.3 inches
- Hole Size:2 inches (top and bottom)
- Material:Dacron
- Compatible Pumps:Intex 530–1500 GPH models; Summer Waves RX/SFX/RP/SFS series
- Recommended Replacement:Every 2 weeks
Our verdict“Buy this pack if you run a small Intex or Summer Waves pool and never want to run out of cartridges mid-season.”
4-Pack Pool Filter Cartridge Replacement for Pentair Clean & Clear Plus 420 (CCP420)
This four-cartridge set targets owners of Pentair Clean & Clear Plus 420 systems who want a complete refill in one purchase. The standout here is the 100% Reemay spunbond polyester media, made in the USA — the same media class used in genuine OEM cartridges, and noticeably more durable than the point-bond fabric found in budget alternatives like the Cryspool C1200. Support bands on each cartridge keep the pleats from collapsing under high flow, which translates to consistent filtration pressure across a full rotation. Compared with the POOLPURE CCP420 four-pack, this set edges ahead on material origin and cleanability, though both are aftermarket rather than the genuine Pentair EC-160301. The real tradeoff is effort: 26-inch cartridges hold a lot of debris, so plan on hosing each one down every few weeks rather than swapping it out.
Pros:- USA-made 100% Reemay media resists wear and holds up to repeated cleaning
- Support bands maintain pleat structure under high flow
- Fits Pentair CCP420, Waterway Crystal Water 105, and Jacuzzi J-CQ420 housings
- Four-cartridge supply supports a full clean/dry/rotate cycle
Cons:- Aftermarket build — not original Pentair parts despite OEM-equivalent media
- Large cartridges require hands-on hose cleaning every few weeks to maintain flow
Best for: In-ground pool owners running a CCP420-class system who want OEM-grade media in a full four-cartridge rotation
Not ideal for: Above-ground pool owners with Intex or Summer Waves pumps — these 26-inch cartridges fit a completely different housing
- Fits:Pentair Clean & Clear Plus 420 (CCP420)
- Quantity:4 cartridges
- Dimensions:26-1/16 in L x 7 in OD x 3 in ID
- Material:100% Reemay spunbond polyester
- Cross-References:Unicel C-7471, Pleatco PCC105, Filbur FC-6470/FC-1977
- Country of Origin:USA
- Weight:21 pounds
Our verdict“This is the pack for serious in-ground pool owners who treat cartridge rotation as a system rather than a one-off purchase.”
Type A or C Replacement Filter Cartridge for Intex Above Ground Pools (4-Pack)
This four-pack of Type A/C cartridges sits in the sweet spot between the two-pack Intex original and the six-pack Volca Spares set. For someone opening a pool for the season and unsure how long cartridges will last, four units cover roughly two months of replacements without the upfront commitment of the six-pack. Like its larger sibling, it fits the full range of Intex pumps up to 1500 GPH and the Summer Waves RX/SFX/RP/SFS canister lineup, and the Dacron media hoses clean in a couple of minutes. Compared with the Intex 29002E two-pack, you get double the quantity from a third-party brand, but the fabric density is a step down from genuine Intex — expect to rinse more often if your pool collects leaves or pollen. It’s a low-risk way to stock up.
Pros:- Four cartridges balance upfront cost against a two-month supply
- Same broad Intex and Summer Waves compatibility as the six-pack
- Dacron media rinses clean quickly with a garden hose
- Good entry point for first-time above-ground pool owners
Cons:- Media density falls short of genuine Intex cartridges
- Frequent pool users will still burn through the pack and need to reorder mid-season
Best for: Budget-minded owners of entry-level Intex or Summer Waves pools who want a mid-size supply without overbuying
Not ideal for: Debris-heavy pools — the thinner aftermarket media clogs quickly under leaf or pollen load
- Cartridge Type:Type A/C (29000E/59900E)
- Quantity:4 cartridges
- Dimensions:8 x 4.3 x 4.3 inches
- Material:Dacron
- Compatible Pumps:Intex 603/604/637R/638R/635T/636T; Summer Waves RX/SFX/RP/SFS series
- Recommended Replacement:Every 2 weeks
Our verdict“Pick this pack if you’re new to cartridge maintenance and want a sensible supply without committing to six.”
Cryspool 08055 Pool Filter Cartridge Replaces CX1200RE, C1200
Where most aftermarket cartridges quietly copy OEM fabric, the Cryspool 08055 leads with trilobal fiber technology — a pleat structure designed to trap fine particles while keeping water flow higher than standard point-bond media. For a big 120 sq. ft. cartridge in a Hayward Star-Clear Plus C1200 housing, that matters: better flow means less pump strain and longer cycles between cleanings. The manufacturer claims a snug, wobble-free fit with no bypass, and the reinforced end caps and pleat bands back that up under high-flow conditions. Compared with the POOLPURE C1200, which fits the same housing, the Cryspool’s edge is its release-friendly fabric — trapped debris rinses out with a garden hose instead of embedding in the pleats. The tradeoff is that it’s an independent brand, so fit tolerances and longevity vary more than with a genuine Hayward CX1200RE, and it comes as a single cartridge rather than a pack.
Pros:- Trilobal fiber media captures fine particles while maintaining higher flow
- Debris releases easily with a standard garden hose rinse
- Reinforced end caps and bands prevent pleat separation under high flow
- Broad cross-compatibility with Unicel, Filbur, Waterway, and Pleatco part numbers
Cons:- Single-cartridge packaging means no spare for rotation during cleaning
- Independent brand — fit and lifespan are less predictable than genuine Hayward parts
Best for: Hayward Star-Clear Plus C1200 owners who want finer filtration and easier cleaning than standard aftermarket cartridges offer
Not ideal for: Owners who want a multi-cartridge rotation or guaranteed OEM fit — this is a single aftermarket unit from an independent brand
- Fits:Hayward Star-Clear Plus C1200 (2006 and newer)
- Filtration Area:120 sq. ft.
- Length:23-5/16 inches
- Outside Diameter:8-15/16 inches
- Opening Size:4 inches (top and bottom)
- Media:Trilobal fiber filtration fabric
- Cross-References:CX1200RE, PA120, Unicel C-8412, Filbur FC-1293, Waterway Clearwater II 125
- Cleaning Interval:Every 2-4 weeks during swim season
Our verdict“Choose this cartridge if clearer water and quicker cleanings matter more to you than sticking with the Hayward name.”
INTEX 29002E Type A Pool Filter Cartridge (2-Pack)
Sometimes the safest buy is the cartridge your pump was designed around, and that’s the case with the genuine Intex 29002E two-pack. Fit is guaranteed across the listed Krystal Clear pump models (28603EG, 28637EG, 28635EG), and the Dacron paper media is denser than the third-party Volca Spares cartridges in this roundup, so it holds shape longer and filters more consistently before clogging. It also pairs with Intex’s HydroAeration Technology, which improves circulation and clarity on compatible systems. The obvious tradeoff is quantity: two cartridges last about a month at the recommended two-week replacement interval, while the six-pack alternative covers a full season for less hassle. Buyers choosing genuine parts are paying for reliability and exact fit rather than volume — a reasonable trade if you’ve had sizing issues with aftermarket cartridges before.
Pros:- Genuine Intex part with guaranteed fit on listed Krystal Clear pump models
- Denser Dacron media outperforms most aftermarket Type A/C cartridges
- Works with HydroAeration Technology for better circulation and clarity
- Easy-to-clean surface simplifies mid-cycle rinsing
Cons:- Only two cartridges per pack — frequent reorders for season-long use
- Higher cost per cartridge than third-party multi-packs
Best for: Intex pool owners who prioritize guaranteed fit and OEM material quality over bulk quantity
Not ideal for: Season-long stocking — two cartridges run out in roughly a month, so bulk buyers should look elsewhere
- Cartridge Type:Type A (29002E)
- Quantity:2 cartridges
- Material:Dacron paper
- Compatible Pumps:Intex 28603EG, 28637EG, 28635EG
- Recommended Replacement:Every 2 weeks
- Brand:INTEX (genuine OEM)
Our verdict“Buy genuine if fit problems with aftermarket cartridges have cost you more than the savings were worth.”
How We Picked
I evaluated each filter against the criteria that actually determine satisfaction in this category: filtration area matched to pool size, build quality of the core and end caps, fit accuracy against OEM part numbers, and cost per cartridge in multi-packs. Because cartridge filters are replacement parts rather than standalone products, correct compatibility carried heavy weight — a well-built cartridge that does not seat properly in the housing is worthless. I also considered longevity signals like pleat count, fabric weight, and whether the manufacturer offers tiered lines (budget, mid, premium) for the same housing.
The ranking logic follows buyer situations rather than raw specs. Full-size in-ground pools benefit most from 420+ sq ft options, so OEM and high-quality aftermarket replacements for the Pentair Clean & Clear Plus line lead the list. Mid-size pools and spas are served by the 100–150 sq ft replacements. Above-ground and entry-level pool owners get dedicated picks at the bottom of the list not because they are worse products, but because they solve a different problem: low-cost, easy-swap filtration for small pumps.
Factors to Consider When Choosing Cartridge Pool Filters
Before clicking buy on any cartridge, it helps to understand how these filters actually behave in a real pool system. The factors below go beyond individual product specs and address the mistakes that cause most buyer regret in this category.Match Square Footage to Your Pool, Not Your Budget
Filtration area determines how much debris your filter can hold before flow drops and the pump works harder. A common mistake is buying the largest cartridge that physically fits, assuming more is always better — but oversized cartridges in a small housing can seal poorly, while undersized ones clog within days on a big pool. As a rough guide, 100–150 sq ft suits spas and small above-ground pools, 175–325 sq ft covers mid-size pools, and 420–520 sq ft is the sweet spot for most in-ground pools. Also remember that multi-cartridge housings like the Clean & Clear Plus 420 use four cartridges working together, so you replace the full set, not one. Buying the right square footage upfront saves you from frequent hosing sessions and premature pump strain.
OEM Versus Aftermarket: When the Price Gap Is Worth It
Genuine OEM cartridges from Pentair and Hayward cost more because of tighter manufacturing tolerances, consistent pleat spacing, and durable cores that survive repeated cleanings. Aftermarket brands like POOLPURE, KGC, and Cryspool have narrowed the gap considerably, and for many owners the savings across a season outweigh the modest durability difference. The honest middle ground is tiered aftermarket lines: budget tiers for occasional use, premium tiers with antimicrobial fabric for pools that run year-round. The riskiest purchase is an unbranded ultra-cheap cartridge with a thin core — these can crack under pressure and allow unfiltered water to bypass the media entirely. If your pool gets heavy use or you clean cartridges aggressively with a pressure washer, the extra spend on OEM or premium aftermarket usually pays back in longevity.
Verify Compatibility Before Anything Else
The most common mistake in this category is ordering by pool brand instead of by filter model. Compatibility runs through part numbers: the Pentair CCP420 accepts cartridges cross-referenced to R173217 and PAP420, while Hayward systems use codes like CX1200RE and CX580XRE. Before ordering, open your filter housing and photograph the existing cartridge’s end caps, dimensions, and any printed numbers — this takes two minutes and prevents the most expensive error in the roundup. Cross-reference charts from Unicel, Pleatco, and Filbur are useful, but a slight difference in cartridge height can cause bypass even when the listing claims a fit. When a listing names multiple compatible part numbers, confirm your exact model appears rather than assuming the series matches.
Single Cartridge Versus Multi-Pack Economics
Cartridge filters are consumables, so the real cost is per cartridge over a season, not the sticker price of one unit. Multi-packs almost always win on cost per cartridge, but only if you rotate and clean them properly — a spare set lets one cartridge dry fully while the other runs, which extends the life of both. Owners who discard cartridges instead of cleaning them should buy the cheapest acceptable tier, since premium antimicrobial fabric is wasted if you throw it away after one cycle. Conversely, if you rinse and reuse cartridges all season, spending more on reinforced cores and heavy pleats delivers genuine value. Match your purchasing pattern to your maintenance habits, not to the discount on the pack size.
Cleaning and Replacement Cycles
A cartridge is not done when it looks dirty — it is done when the filter pressure gauge rises 8–10 PSI above the clean baseline. Most cartridges tolerate five to seven cleanings before the pleats lose their trapping ability, and fabric that feels stiff or has visible scale should be retired. Above-ground cartridges like the Intex Type A are designed for far shorter cycles because of their small media area, so expecting a full season from one set leads to cloudy water and frustrated owners. Soaking cartridges in a cleaning solution dissolves body oils and sunscreen that hosing alone cannot remove, and it can double the useful life of a premium cartridge. Budget for roughly one full replacement set per season on a heavily used in-ground pool, more on small above-ground systems.
Above-Ground and Entry-Level Systems Are a Different Market
Small above-ground pool cartridges trade filtration performance for convenience and low cost, and judging them by in-ground standards sets the wrong expectations. Type A and C cartridges for Intex pumps filter adequately for pools of a few thousand gallons but need rinsing weekly and replacement monthly during peak season. The mistake to avoid is trying to upgrade cartridge quality in a small pump housing — the pump flow rate, not the cartridge, is the limiting factor. If your above-ground pool consistently runs cloudy, the better investment is a larger filter system like the XtremepowerUS 175 sq ft unit rather than a better cartridge for a small pump. Spend on the system that matches your pool volume, and let the cartridge quality follow.
Frequently Asked Questions
Can I upgrade my Pentair CCP420 housing with higher square footage cartridges?
No, and attempting to do so usually backfires. The CCP420 housing is engineered around four cartridges with a fixed height, diameter, and end-cap spacing, so a taller or wider cartridge will either not seat or will leave gaps that let unfiltered water bypass the media. What you can do is upgrade cartridge quality within the correct size — for example stepping from a basic aftermarket tier to a reinforced or antimicrobial version, or to genuine Pentair cartridges. If you genuinely need more filtration area because your filter cycles constantly, the real solution is a larger housing like the Clean & Clear Plus 520, not an oversized cartridge in your existing one. Always match the part number rather than shopping by maximum square footage.
How often should I replace versus clean cartridge pool filters?
Clean whenever the pressure gauge rises 8–10 PSI above your clean baseline, which for most in-ground pools means every few weeks during swimming season. Each cartridge tolerates roughly five to seven cleanings before the pleats become compacted and stop trapping effectively, so a typical set lasts one to two seasons depending on use. Small above-ground cartridges like the Intex Type A follow a different rhythm — rinse weekly and replace monthly, because their small media area saturates far faster. When fabric feels stiff, shows white scale that does not dissolve, or pleats are torn at the seams, retire the cartridge regardless of cleaning count. Keeping a spare set in rotation lets each cartridge dry completely between uses, which slows bacterial growth and extends total life.
Are aftermarket cartridges like POOLPURE and KGC actually as good as OEM?
For most pool owners, quality aftermarket cartridges are close enough that the price difference makes them the smarter buy. The genuine OEM options from Pentair and Hayward hold an edge in pleat consistency, core strength, and end-cap fit, which matters most if you pressure-wash cartridges or run your pool year-round in a hot climate. Where aftermarket brands vary is quality control — the same brand can produce an excellent four-pack and a mediocre single unit, so sticking with established names with clear cross-reference charts reduces risk. If a cartridge arrives with uneven pleats, loose end caps, or a chemical smell that does not wash out, return it rather than installing it. My general rule: use premium aftermarket for routine seasonal replacement, and reserve OEM spend for housings under warranty or pools with heavy bather loads.
Do I need to replace all four cartridges in a Clean & Clear Plus 420 at once?
Not necessarily, though replacing the full set at once keeps performance balanced and simplifies tracking. Because the four cartridges share the same water flow, a mix of new and worn cartridges sends more water through the cleaner ones, causing them to clog faster and wear unevenly. If one cartridge is damaged mid-season, swapping just that one is fine as a stopgap, but expect to replace the rest soon after. Buying the four-pack format makes the most sense economically, since the cost per cartridge drops well below singles and you will need the full set within the same season anyway. One practical approach is rotating two pairs — replace two, then the other two a few months later — which spreads cost while keeping flow reasonably balanced.
Why does my small above-ground pool stay cloudy even with fresh Type A cartridges?
Because the cartridge is rarely the bottleneck — the pump is. Intex-style filter pumps move relatively little water per hour, and their small Type A cartridges saturate within days on a pool of any real volume, so even brand-new cartridges cannot keep up with algae and fine particles. First confirm your chemistry is balanced, since no filter can clear cloudiness caused by poor sanitizer or pH levels. If chemistry is right and the pool still clouds, the upgrade path is a larger cartridge system like the XtremepowerUS 175 sq ft filter with its 2-inch ports, which moves and polishes far more water. Also try running the pump longer each day — small systems often need 8–12 hours of circulation in summer. Throwing more replacement cartridges at an undersized pump just wastes money.
Conclusion
For most in-ground pool owners, the Pentair EC-160301 Clean & Clear Plus 420 is the best overall choice — genuine fit, serious filtration area, and durability that survives season after season. Value shoppers should look at the POOLPURE CCP420 four-pack, which captures most of that performance at a much lower cost per cartridge, while the POOLPURE CCP520 four-pack is the premium pick for oversized pools needing maximum filtration area. Spa owners and those with smaller Pentair housings are well served by the POOLPURE CC150 or CC100, and Hayward owners get a dedicated strong option in the POOLPURE C1200 or KGC C3030 four-pack depending on their system size. Beginners with Intex above-ground pools should keep it simple with the INTEX 29002E Type A two-pack, and anyone outgrowing a small pump entirely should jump to the XtremepowerUS 175 sq ft system rather than buying better cartridges for undersized equipment. Match the cartridge to your housing, buy in packs if you clean and reuse, and the rest of this category takes care of itself.
