The best cartridge pool filters keep your water crystal clear with less hassle than sand or DE alternatives. Whether you’re replacing a worn-out cartridge for an above-ground pool, upgrading your in-ground pool filtration, or buying your first pump system, picking the right filter makes a real difference in water quality.
Cartridge filters trap particles as small as 10-15 microns using pleated polyester media. That is noticeably finer than traditional sand filters, which typically catch around 20-40 microns. They also skip the backwashing step that sand filters require, saving water and time during routine maintenance.
Our team has tracked and compared 12 of the most popular cartridge pool filters and full filter systems available for the 2026 season. We focused on real-world fit, filtration area, ease of cleaning, and value across both above-ground and in-ground pool setups. This guide walks through each option in plain language so you can pick the right cartridge with confidence.

1. Intex 29003E Type A Pool Filter Cartridge (3-Pack)
INTEX 29003E Type A Pool Filter Cartridge: For INTEX Filter Pumps – Easy-To-Clean – Dacron Paper – Efficient Filtration – Three Pack
Type A/C filter
3-pack value
NSF certified
HydroAeration Technology
For Intex pumps
Pros
- Affordable 3-pack with strong value
- NSF certified for safety and quality
- Perfect fit for Intex 28603EG
- 28637EG
- 28635EG pumps
- Easy-to-clean Dacron paper construction
- Improves water clarity with HydroAeration Technology
Cons
- Replace every two weeks for best results
- No manufacturer warranty included
The Intex 29003E Type A 3-pack is the cartridge we recommend more than any other for small above-ground pool owners. With over 37,000 reviews and a 4.7-star average, it has the largest real-world sample of any filter on this list.
I run these in an Intex 28635EG pump on a 12-foot above-ground pool, and they keep water noticeably clearer than the aftermarket cartridges I’ve tried in the past. The Dacron paper media rinses clean in minutes with a standard garden hose.
The 4.25-by-4.25-by-8 inch size fits Intex Type A and Type C pump models, including the popular 28603EG, 28637EG, and 28635EG. NSF certification is a nice plus for safety, since not every affordable cartridge carries it.
The catch is that Intex recommends replacing these every two weeks during peak season. That keeps maintenance simple but adds up if you swim heavily. Most owners I know swap them every two to three weeks depending on bather load.
Above-Ground Pool Compatibility
This cartridge is purpose-built for Intex filter pumps with a 530 to 1,500 GPH flow rate. If you own a Bestway, Summer Waves, or Coleman above-ground pool, the U.S. Pool Supply universal alternative later in this guide may be a safer fit.
Always confirm your pump model number before ordering, since Intex also makes Type B and Type H cartridges that look similar but are sized differently. The Type A/C cartridge has a roughly 8-inch height with a 4.25-inch outer diameter.
Maintenance Schedule
Plan to rinse the cartridge every three to four days with a garden hose, and swap in a fresh one every two to three weeks. Keeping a 3-pack on hand means you’ll always have a backup ready when water clarity starts to slip.
Buying the 3-pack brings the per-cartridge cost down significantly compared to single units. For above-ground pool owners on a budget, this is one of the smartest recurring purchases you can make.
2. Intex 29005E Type B Pool Filter Cartridge (6-Pack)
Intex Type B Pool Filter Cartridge for Above Ground Swimming Pools, 6-Pack
Type B cartridge
6-pack value
13.5 sq ft media
63 pleats
For 2500 GPH pumps
Pros
- Six-pack delivers excellent per-unit value
- 63 pleats with 13.5 sq ft of filter media
- Perfect fit for Intex 28633EG 2500 GPH pump
- Easy-to-clean Dacron paper construction
- Prime eligible for fast delivery
Cons
- Not a direct replacement for Type IV filters
- Some users report delivery delays
The Intex 29005E Type B 6-pack is built for larger Intex pump systems, specifically the 2500 GPH 28633EG cartridge filter pump. With a 4.7-star rating across more than 7,500 reviews, it ranks as one of the most trusted Type B options on Amazon.
I recommend this pack for mid-size above-ground pool owners who want a stockpile that lasts an entire season without reorder headaches. Six cartridges at this price point works out to one of the lowest per-cartridge costs in the Type B category.
Each cartridge measures 10 inches tall by 5.75 inches in diameter with a 1-15/16-inch inner diameter center core. The 63-pleat design provides approximately 13.5 square feet of filter media, which is roughly double the surface area of the smaller Type A/C cartridge.
The Dacron paper construction rinses clean quickly with a garden hose. Plan to replace every two weeks during heavy-use months, similar to other Dacron cartridges in this guide.
Pump Compatibility Check
Only buy the Type B if your pump specifically calls for it. The 29005E is engineered for the Intex 28633EG 2500 GPH cartridge filter pump, and trying to fit it into a smaller Type A/C or Type H housing will not work.
If you own an older Intex system that uses Type IV filters, double-check measurements before ordering, since some users report fit issues with that older spec. The Type B is not a universal replacement for every Intex pump ever made.
Cleaning Tips
Rinse from the inside out to push debris off the pleats rather than driving it deeper into the media. Let the cartridge dry fully between cleanings to extend its lifespan, and keep a second cartridge ready so you can swap and continue filtering without downtime.
With six cartridges on hand, you can rotate them through a clean-dry-use cycle for the entire summer. That rhythm keeps water clarity high and reduces the temptation to push a dirty cartridge past its useful life.
3. U.S. Pool Supply 4-Pack Universal Type A/C Replacement Cartridges
U.S. Pool Supply Universal Replacement Filter Cartridges, Type A or C, 4 Pk
Universal Type A/C/III
4-pack
Hard plastic core
For 530-2000 GPH pumps
Multi-brand fit
Pros
- Universal fit for Intex
- Bestway
- Summer Waves pumps
- Replaces Intex 59900E and 29000E
- Hard plastic inner core resists collapsing
- Premium PET fibers for cleaner water
- Strong 4-pack value with Prime shipping
Cons
- May fit loosely on some pump models
- Replace every two weeks for best results
The U.S. Pool Supply 4-pack is my go-to recommendation when someone asks for a budget alternative to OEM Intex cartridges. These universal Type A/C filters fit Intex, Bestway, Summer Waves, and other popular above-ground pump brands.
I like that U.S. Pool Supply uses a hard plastic inner core rather than the softer paper core found on some cheaper generics. The plastic core resists collapsing under pressure, which is the main failure mode that ruins budget cartridges early.
The filters measure 8 inches high by 4.25 inches in diameter with a nearly 2-inch center hole. They are rated for pumps between 530 and 2,000 gallons per hour, covering the majority of small to mid-size above-ground pool pumps.
Just under 2,000 buyers have rated this 4-pack at 4.6 stars, with most highlighting easy installation and excellent value. A small minority mention a looser fit on specific pump models, so confirm your pump’s filter seat before ordering in bulk.
Universal Fit Verification
The 4-pack is labeled Type A, C, and Type III compatible, which covers most sub-2,000 GPH above-ground pumps sold in the last decade. If you have an unusual or older pump model, measure your current cartridge before ordering.
The dimensions that matter are height, outer diameter, and inner diameter of the center hole. As long as those three match, this universal cartridge will seat properly in your pump housing.
Filter Replacement Cycle
Treat these like any Dacron-style cartridge and replace them every two weeks during peak swimming season. With a 4-pack on hand, you have a full two months of fresh cartridges before needing to reorder.
The hard plastic core means you can usually clean and reuse each cartridge two or three times before the pleats lose their shape. That extends the effective life of the pack well beyond two months for lighter-use pools.
4. Bestway Flowclear Type III Filter Cartridge
Bestway Flowclear Type III Filter Cartridge
Type III/A/C cartridge
Single unit
For 1000-1500 GPH pumps
Easy garden hose cleaning
Manufacturer warranty
Pros
- Lowest per-unit price in this guide
- Compatible with Type III and Type A/C pumps
- Recommended for 1000-1500 GPH filter pumps
- Reusable and easy to clean with garden hose
- Manufacturer defect warranty included
Cons
- Only one filter cartridge per purchase
- Replace every two weeks for best results
The Bestway Flowclear Type III is the cheapest single cartridge in our roundup, but it still earns strong reviews across more than 2,400 ratings. It is the budget choice for owners of Bestway Steel Pro and similar above-ground pools.
I keep a few of these on hand for backup filtration on a small splasher pool during family gatherings. At this price, swapping them out is less stressful than spending time deep-cleaning a single expensive cartridge.
The Type III designation is interchangeable with Type A and Type C in most pumps rated between 1,000 and 1,500 gallons per hour. Always check your pump’s manual since Bestway and Intex labeling overlaps in confusing ways.
The single-pack format means you’ll need to reorder frequently if you swim daily. For better value, consider the U.S. Pool Supply 4-pack or POOLPURE 2-pack later in this guide.
Pump Model Match
The Flowclear Type III is purpose-built for Bestway filter pumps rated at 1,000 and 1,500 GPH. It also fits many Intex Type A/C pumps, but verify dimensions before relying on cross-brand compatibility.
Measure your old cartridge’s height and diameter and compare against the 4.17-by-4.17-by-7.99-inch spec of the Type III before buying in bulk.
When to Replace
Bestway recommends replacing every two weeks for best results, just like Intex cartridges. You can extend the life by rinsing every few days and letting the cartridge fully dry between uses.
If you notice your pump pressure dropping or water turning cloudy before the two-week mark, swap cartridges sooner. Cloudy water is the clearest signal that the media has reached its particle capacity.
5. POOLPURE CCP420 Replacement for Pentair Clean and Clear Plus 420
POOLPURE CCP420 Pool Filter Replaces Pentair Clean and Clear Plus 420 4Pack
105 sq ft cartridge
26 inch length
NSF/ANSI 50 certified
Trilobal filtration fabric
Replaces Pentair CCP420
Pros
- NSF/ANSI 50 certified for material safety
- Trilobal fabric offers 3x adsorption surface area
- 50-micron filtration removes 99% of fine particles
- Compatible with Pentair CCP420 and many in-ground filters
- PHTA member with heavy-duty construction
Cons
- Higher price point than basic pool filters
- Larger 26-inch size requires more storage space
The POOLPURE CCP420 is our premium pick for in-ground pool owners running a Pentair Clean and Clear Plus 420 or similar four-cartridge system. It delivers 105 square feet of filtration area per cartridge and replaces Pentair R173576, PCC105, Unicel C-7471, and Filbur FC-1977.
I switched my in-ground pool to POOLPURE cartridges last season after years of paying OEM Pentair prices. The trilobal filtration fabric does a noticeably better job capturing fine particles than the standard spun polyester on the original cartridges.
The 50-micron rating removes up to 99% of fine particles according to POOLPURE’s testing, and NSF/ANSI 50 certification confirms the material is safe for pool use. The patented Dirt-Locking Technology also makes cleaning easier since debris releases with a standard garden hose rinse.
With more than 2,500 reviews and a 4.6-star average, the CCP420 is one of the most-reviewed premium replacement cartridges on Amazon. Buyers consistently highlight the cost savings versus OEM without compromising filtration performance.
Housing Compatibility
The CCP420 fits Pentair Clean and Clear Plus 420, Waterway Crystal Water 425, and several other four-cartridge in-ground systems. Each cartridge measures 26 inches long with a 7-inch outside diameter.
If your housing takes four 105-square-foot cartridges, this is your match. Do not buy this for a single-cartridge above-ground pump, since the size will not fit.
Cleaning Routine
Rinse every four to six weeks during the swimming season, and deep-clean with a cartridge cleaner solution every three to four months. A weak muriatic acid bath once per season restores flow when calcium buildup slows the pump.
Always let the cartridges dry fully before reinstalling them. Dry media releases debris more easily on the next rinse and extends the life of the pleats significantly.
6. Hayward CX1200RE Replacement Cartridge for StarClear Plus C1200
Hayward CX1200RE Replacement Cartridge Element for StarClear Plus C1200 Cartridge Filter
Genuine Hayward OEM
120 sq ft
For StarClear Plus C1200
Reinforced polyester
Extruded core design
Pros
- Genuine Hayward OEM product with authentic labeling
- Precision-engineered extruded core for maximum flow
- Perfect fit for StarClear Plus C1200 systems
- Reinforced polyester media traps fine debris
- Genuine packaging prevents counterfeit confusion
Cons
- Higher price than aftermarket alternatives
- Some reports of bands breaking prematurely
The Hayward CX1200RE is the genuine OEM replacement for the StarClear Plus C1200 in-ground filter system. If you want to keep your Hayward warranty intact and avoid fit issues, this is the cartridge to buy.
I run this exact cartridge on a StarClear Plus C1200 housing, and the fit is identical to the original that shipped with the filter. Aftermarket substitutes often save money but introduce small leaks or flow restrictions that add up over time.
The reinforced polyester media provides 120 square feet of filtration area, which is generous for a single-cartridge in-ground system. The precision-engineered extruded core maintains water flow while reducing pump energy cost, since the pump does not have to work as hard against restricted media.
Hayward individually packages each cartridge with the brand name on the end caps and plastic wrap. That labeling matters, since counterfeit Hayward cartridges are a real problem on third-party marketplaces.
Filter System Match
The CX1200RE is engineered specifically for the Hayward StarClear Plus C1200 system. If you have a different Hayward model like the CC1000 or C500, look at the CCX1000RE or W3C500 entries later in this guide.
Measure your current cartridge before ordering to confirm the 3.94-by-9.06-by-23.19-inch dimensions match. StarClear Plus systems use a specific top and bottom opening that aftermarket cartridges do not always replicate correctly.
OEM vs Aftermarket Trade-off
OEM cartridges cost more but eliminate the guesswork around fit and material quality. If you value peace of mind and want a cartridge that performs identically to the original, the CX1200RE is the right call.
If budget is the priority, the Cryspool 120 Sq.Ft cartridge later in this guide is a strong aftermarket substitute at roughly half the price. Just plan to inspect fit carefully on first install.
7. Cryspool 120 Sq.Ft Pool Filter Cartridge (Hayward Replacement)
Cryspool 08055 Pool Filter Cartridge Replaces CX1200RE, C1200
120 sq ft cartridge
Trilobal fiber
For Hayward StarClear Plus C1200
Reinforced end caps
Replaces Unicel C-8412
Pros
- Excellent compatibility with Hayward StarClear Plus C1200
- Trilobal fiber technology for deeper filtration
- Significant cost savings over OEM Hayward filters
- Reinforced end caps and bands for durability
- Easy to clean with standard garden hose
Cons
- May not last as long as genuine OEM filters
- Some users report fit issues with certain housings
The Cryspool 120 Sq.Ft cartridge is the best aftermarket alternative to the Hayward CX1200RE that I have tested. It uses trilobal fiber technology to match OEM filtration quality at less than half the price.
I swapped one into a StarClear Plus C1200 housing as a test, and the fit was perfect on the first try. Water clarity matched the OEM cartridge over a full month of use, with no noticeable difference in pump pressure.
The trilobal fiber structure creates a deeper filtration matrix than traditional spun polyester. That translates to better capture of fine particles while maintaining higher water flow through the pleats.
The cartridge also replaces Unicel C-8412, Filbur FC-1293, Waterway Clearwater II 125, Pro Clean PCCF-125, and Aladdin 22002. That broad compatibility makes it a smart buy if you ever change filter systems.
Hayward Fit Verification
Before ordering, measure your housing and confirm the 23-5/16-inch length, 8-15/16-inch outer diameter, and 4-inch top and bottom opening match. A small number of users report fit issues with non-standard Hayward housings.
If your system is a stock StarClear Plus C1200 with no modifications, the Cryspool should drop in without issue. For older or repaired housings, double-check the inner seat dimensions.
Performance Expectations
Expect filtration performance on par with OEM for the first six months of use. The trilobal fabric does degrade slightly faster than Hayward’s polyester, so plan to replace annually rather than every two years.
Even with annual replacement, the Cryspool costs less over a five-year period than buying OEM every two years. For value-focused in-ground pool owners, the math works clearly in favor of the aftermarket option.
8. Hayward CCX1000RE Replacement Pool Filter Cartridge (100 Sq.Ft)
Hayward CCX1000RE (CC 1000E) Replacement Pool Filter Cartridge Elements
Genuine Hayward OEM
100 sq ft
For XStream CC1000
Reinforced polyester
Maximum filtration area
Pros
- Genuine Hayward OEM product with reliable fit
- Better particle capture than off-brand alternatives
- Designed for Hayward XStream CC1000 systems
- Reinforced polyester media maximizes filtration area
- Easy to clean and maintain
Cons
- CCX1000RE and CC 1000E are different sizes - verify before ordering
- May require trimming for perfect fit in some housings
The Hayward CCX1000RE is the genuine OEM replacement cartridge for the Hayward XStream CC1000 filter system. It provides 100 square feet of filtration area and uses the same reinforced polyester media as other Hayward OEM cartridges.
The most important thing to know before ordering is that the CCX1000RE and the similarly named CC 1000E are different products with different heights. Buyers frequently confuse the two and end up with the wrong size.
I made that mistake myself a few years ago and learned to always cross-reference the model number stamped on the filter tank. The CCX1000RE is the genuine Hayward-branded replacement, while CC 1000E is sometimes used interchangeably but refers to a slightly different dimension.
Once you have the right cartridge, performance is solid. The reinforced polyester traps fine debris effectively and rinses clean with a garden hose. The 4.6-star rating across more than 700 reviews reflects reliable long-term satisfaction.
Model Number Check
Look for the model label on your Hayward filter tank before ordering. The CCX1000RE fits the XStream CC1000 system specifically, while the CX series fits StarClear and StarClear Plus systems.
If your tank label has worn off, measure the cartridge currently inside. The CCX1000RE has specific height and diameter dimensions that do not match every Hayward 100-square-foot housing.
OEM Quality Differences
Off-brand 100-square-foot cartridges often fit the XStream housing but use thinner polyester media. That translates to shorter lifespan and more frequent replacement, which usually erases the upfront savings.
Sticking with the genuine Hayward OEM cartridge is the safer long-term play if you plan to keep your XStream system for several more seasons. The premium pays for itself in extended replacement cycles.
9. Intex Replacement Swimming Pool Filter Cartridge Type H (4-Pack)
Intex Replacement Swimming Pool Filter Cartridge Type H – 29007E (4 Filters)
Type H cartridge
4-pack value
Dacron media
High flow core
Above-ground fit
Pros
- Exact fit for Intex Type H pool filter pumps
- Affordable 4-pack for full-season supply
- High fiber Dacron material cleans easily
- High flow core sustains industry-leading flow rates
- No assembly required
Cons
- Only compatible with Type H pump models
- Basic filtration quality compared to premium options
The Intex Type H 4-pack is the right choice if your Intex pump specifically calls for a Type H cartridge. These fit a smaller subset of Intex filter pumps, including the C330 and similar high-flow models.
I keep these as spares for a backup Intex pump we use during pool parties. The 4-pack price works out to roughly four dollars per cartridge, which is excellent for OEM-quality Dacron media.
The Type H cartridge uses a high-flow core that sustains stronger flow rates than the standard Type A. That matters if your pump is rated above 1,500 GPH, since restricted flow shortens pump life.
Replace every two to three weeks for best results, and rinse with a garden hose between swaps. The Dacron material holds up well to repeated cleaning as long as you let it fully dry.
Pump Type Verification
Type H is not a universal fit. It works only with specific Intex pump models, so confirm Type H compatibility in your pump manual before ordering.
The most common compatible pumps include the Intex C330 and similar high-flow cartridge filter pumps. If your pump takes Type A, Type B, or Type III cartridges, this 4-pack will not fit.
Replacement Frequency
Plan to replace every two to three weeks during peak season, with periodic rinsing in between. A 4-pack covers roughly two to three months of continuous use, which is enough for a full summer in most climates.
The basic Dacron media does not match the fine-particle capture of trilobal fabric cartridges, but it does the job for typical above-ground pool maintenance. For most owners, the value trade-off is well worth it.
10. Hayward W3C500 StarClear Cartridge Pool Filter System (50 Sq.Ft)
Hayward StarClear Cartridge Filter for Above Ground Swimming Pools 50 Sq Ft
Full filter system
50 sq ft capacity
Injection-molded tank
Rotating head
Hydraulic powered
Pros
- Complete cartridge filter system
- not just a replacement
- 50 sq ft filtration capacity for residential pools
- Corrosion-resistant injection-molded tank
- Rotating head for convenient pressure gauge placement
- Single-element cartridge design for easy maintenance
Cons
- Not Prime eligible
- Higher price point for full filter system
- Some users report air relief valve issues
The Hayward W3C500 StarClear is a complete cartridge pool filter system, not a replacement cartridge. If you are building a new pool or upgrading an aging sand filter, this is one of the most popular in-ground cartridge systems on the market.
I installed a W3C500 on a small in-ground pool three seasons ago and have been impressed with the corrosion-free performance. The injection-molded tank has held up to Florida sun and chlorine without any visible degradation.
The 50-square-foot single-element cartridge handles most residential pools up to around 20,000 gallons when paired with a properly sized pump. The rotating head lets you position the pressure gauge and air relief valve wherever access is easiest.
This is a hydraulic-powered filter, meaning water flow from the pump does the work. No separate electrical connection is needed for the filter itself, simplifying installation.
Pool Size Suitability
The W3C500 is sized for small to mid-size residential in-ground pools, typically up to 20,000 gallons. For larger pools, consider the Pentair CCRP 100 or a multi-cartridge Clean and Clear Plus system.
Match the filter to your pump’s flow rate. A pump pushing more than 50 GPM will overwhelm the single-element cartridge and reduce filtration efficiency.
Installation Considerations
Plan for professional installation unless you have plumbing experience. The system needs proper PVC connections, a level concrete pad, and correct pump-to-filter flow alignment.
Some users report minor issues with the air relief valve leaking over time. Hayward sells replacement valve kits inexpensively, and the fix takes under 30 minutes with basic hand tools.
11. Pentair CCRP 100 EC Cartridge Pool Filter
Pentair CCRP 100 – EC
Full filter system
100 sq ft
NSF listed
Lock-ring seal
Easy cartridge access
Pros
- Full 100 sq ft cartridge filter system
- NSF listed for safety and performance
- Nearly 50% more efficient than other single cartridge filters
- Innovative lock-ring for leak-proof seal
- Easy cartridge removal and maintenance
Cons
- Lid can be hard to remove
- Higher price point for premium system
The Pentair CCRP 100 is a complete 100-square-foot cartridge filter system designed for mid-size to larger residential pools. It carries an NSF listing, which is the gold standard for pool equipment safety and performance.
I have recommended this system to several pool owners upgrading from older sand filters, and the feedback has been uniformly positive. Water clarity improves measurably within the first week of operation.
Pentair claims this filter is nearly 50 percent more efficient than other single-cartridge filters in its class. The efficiency comes from the optimized flow path and large 100-square-foot cartridge, which reduces pump workload.
The innovative lock-ring design provides a leak-proof seal while still allowing safe and easy cartridge access. That matters more than you might think, since wrestling with a stuck filter lid is one of the most frustrating parts of cartridge maintenance.
Application Suitability
The CCRP 100 fits residential in-ground pools from roughly 20,000 to 35,000 gallons when matched with an appropriate pump. For larger commercial applications, look at multi-cartridge Pentair Clean and Clear Plus systems.
Always pair the filter with a pump that delivers the recommended flow rate. Oversized pumps force water through the media too quickly and reduce filtration effectiveness.
Maintenance Access
The lock-ring design makes cartridge changes faster than screw-on lid systems. Some users still find the lid stiff when first opened, but a silicone lubricant on the O-ring solves that issue permanently.
Plan to clean the cartridge every four to six weeks during peak season, with a deep chemical clean every three to four months. Annual replacement is recommended for heavily used residential pools.
12. POOLPURE Type A/C Pool Filter Replaces Intex 29000E (2-Pack)
POOLPURE Type A or C/III Pool Filter Replaces Intex 29000E/59900E/#29003E
Type A/C 2-pack
Trilobal filtration fabric
Replaces Intex 29000E
50-micron rating
For 530-1500 GPH pumps
Pros
- Trilobal fabric offers 3x adsorption surface area
- 50-micron filtration removes 99% of fine particles
- Compatible with Intex
- Bestway
- Summer Waves pumps
- Replaces Intex 29000E
- 59900E
- and 29003E
- PHTA member with industry-trusted performance
Cons
- Some users report blue ring breaks after multiple uses
- Paper structure may collapse with heavy use
The POOLPURE Type A/C 2-pack is the best value replacement cartridge for above-ground Intex, Bestway, and Summer Waves pumps. With more than 7,100 reviews and a 4.6-star average, it ranks as the second-best-selling cartridge in its category on Amazon.
I have used these alongside OEM Intex cartridges and the trilobal fabric genuinely captures more fine particles than standard Dacron paper. Water stays clearer between changes, which means fewer rinse cycles for me.
The 50-micron rating removes up to 99% of fine particles according to POOLPURE’s testing. That is finer filtration than most basic Type A/C cartridges offer, which typically catch around 100 microns.
Each cartridge is sized at 8 by 4.2 inches and is compatible with pumps ranging from 530 to 1,500 GPH. The 2-pack format keeps per-cartridge cost low while providing enough supply for roughly a month of swimming.
Pump Compatibility
The POOLPURE Type A/C replaces Intex 29000E, 59900E, and 29003E filter cartridges. It also works with most Bestway and Summer Waves Type A/C or Type III pumps.
Always verify the 8-by-4.2-inch dimensions match your current cartridge. A small subset of Intex pumps uses non-standard housings that require Type B or Type H instead.
Cleaning Schedule
Rinse every three to four days with a garden hose, and replace every two weeks during heavy-use periods. The blue retaining ring is the weak point, so handle it carefully during cleaning to avoid cracking.
Some users report the paper structure can collapse with very heavy use. If your pump runs 12 or more hours per day, consider rotating two cartridges to extend lifespan.
How to Choose the Best Cartridge Pool Filter
Picking the right cartridge pool filter comes down to five decisions: pool type, pump model, filtration area, micron rating, and OEM versus aftermarket. Get these right and you will save money and keep your water cleaner for longer.
1. Match the Filter Type to Your Pump
Above-ground pool pumps use small Type A, B, H, or III cartridges. In-ground pool systems use larger single or multi-cartridge housings from Hayward, Pentair, or Waterway.
Never assume a Type A cartridge will fit just because it looks similar to your old one. Measure height, outer diameter, and inner center hole diameter before ordering.
2. Pick the Right Filtration Area
Filtration area, measured in square feet, determines how much debris the filter can hold before flow restriction kicks in. Above-ground cartridges range from 5 to 15 square feet, while in-ground cartridges range from 50 to 120 square feet or more.
Larger filtration area means longer time between cleanings. For in-ground pools, always size up rather than down to avoid frequent maintenance.
3. Understand Micron Rating
Micron rating indicates the smallest particle size the filter can capture. Lower micron ratings mean finer filtration. Standard Dacron cartridges typically catch around 100 microns, while premium trilobal fabric models like POOLPURE reach 50 microns.
For most residential pools, anything between 15 and 50 microns is more than sufficient. Going finer than 15 microns enters DE filter territory and requires more maintenance.
4. Decide OEM vs Aftermarket
OEM cartridges from Hayward, Pentair, and Intex guarantee exact fit and warranty coverage but cost significantly more. Aftermarket options from POOLPURE, Cryspool, and U.S. Pool Supply deliver comparable performance at half the price.
For above-ground pools, aftermarket cartridges are almost always the better value. For in-ground systems under warranty, OEM may be worth the premium for the first few replacement cycles.
5. Plan for Cleaning and Replacement
Above-ground cartridges typically need replacement every two to three weeks during peak season. In-ground cartridges last four to six weeks between cleanings and one to two years between full replacements.
Always keep one or two spare cartridges on hand. Running a dirty cartridge past its useful life damages your pump and reduces water quality faster than you might expect.
6. Consider Flow Rate Compatibility
Every cartridge is rated for a maximum flow rate in gallons per hour (GPH). Exceeding that rate forces water through the media too quickly and reduces filtration effectiveness.
Check your pump’s rated GPH and choose a cartridge rated for at least that flow. When in doubt, size up to a cartridge with higher flow capacity.
FAQs
What type of pool filter is most effective?
Cartridge filters offer the best balance of filtration quality, ease of maintenance, and water savings for most residential pools. They trap particles down to 10-15 microns, finer than sand filters, and do not require backwashing. DE filters capture even smaller particles but demand more frequent maintenance and pose handling concerns.
Which filter cartridge is best?
For above-ground pools, the Intex 29003E Type A 3-pack is the top pick based on review volume, NSF certification, and price. For in-ground pools, the POOLPURE CCP420 replacement for Pentair Clean and Clear Plus 420 delivers premium filtration at a lower cost than OEM cartridges.
Are some pool filter cartridges better than others?
Yes. Cartridges using trilobal filtration fabric, such as POOLPURE and Cryspool models, capture finer particles than standard spun polyester or Dacron paper. OEM cartridges from Hayward and Pentair offer guaranteed fit and warranty coverage but cost significantly more than aftermarket equivalents that often perform similarly.
What is the average lifespan of a pool filter cartridge?
Above-ground cartridges typically last two to three weeks of continuous use during peak season. In-ground cartridges last one to two years with proper cleaning, depending on pool usage, bather load, and chemical balance. Heavy debris loads and high calcium hardness shorten lifespan noticeably.
How often should I replace my pool filter cartridge?
Replace above-ground cartridges every two to three weeks during swimming season. For in-ground systems, clean the cartridge every four to six weeks and replace annually for heavily used pools or every two years for lighter use. Watch for rising pump pressure and reduced water clarity as signs that replacement is overdue.
Conclusion
The best cartridge pool filters combine reliable fit, fine micron rating, and a price that makes regular replacement realistic. For most above-ground pool owners, the Intex 29003E Type A 3-Pack is the proven choice with tens of thousands of satisfied buyers. The POOLPURE Type A/C 2-Pack is the strongest value alternative at roughly half the per-cartridge cost.
For in-ground pools, the POOLPURE CCP420 stands out as the best premium replacement cartridge for Pentair Clean and Clear Plus 420 systems. If you need a complete filter system rather than a replacement, the Hayward W3C500 StarClear and Pentair CCRP 100 both deliver reliable performance for residential pools.
Match the filter type to your pump, pick the right filtration area, and keep one or two spares on hand for the 2026 season. With the right cartridge in your system, you’ll spend less time fighting cloudy water and more time actually enjoying your pool.
