A cloudy pool after a backyard party or a stretch of hot weather is the kind of problem that sneaks up on you. The fix usually lives inside the filter housing, not in the pump itself, which is why picking the right media matters more than most people expect. This roundup focuses on eight replacement options across DE grids, cartridge filters, and a few related parts, so the right match for your setup is easy to spot.
How The Shortlist Stacks Up
INTEX 29002E Type A Pool Filter Cartridge 2-Pack
Intex Type A Pool Filter Cartridge 3-Pack
Aumzong 60 Sq Ft DE Pool Filter Grids 30 inch
Pentair 270141 Push Pull Valve and Pump Union
Yoozell PCC130 Replacement Cartridge 4-Pack
Yoozell PCC105 Replacement Cartridge 4-Pack
Yoozell YZ688E System 3 S7M120 Cartridges 300 Sq Ft
Yoozell 85 Sq Ft Pool Filter Cartridge 4-Pack
Taking A Closer Look At The Options
If your backyard runs on a Krystal Clear pump from Intex, the Type A cartridge is the spare you keep within arm’s reach. Compared with the larger cartridge options later in this list, this one is sized for smaller above-ground pools and filters in the 530 to 1,000 gallon per hour range, so a single rinse cycle handles a normal weekend of use.
The Dacron paper media is built to be reused rather than tossed, which keeps the long-term waste down. The two-pack format means you rotate a clean cartridge in while the dirty one dries, a small rhythm that keeps water clarity steady during peak swim weeks.
Useful Touches
- Dacron paper holds up to repeated rinse cycles, so replacement cost stays flat across a full swim season.
- Two cartridges in the box reduce the chance a worn-out element catches you off guard mid-summer.
- Direct fit with Intex 28603EG, 28637EG, and 28635EG pump models means no adapter or modification is needed.
- Lightweight construction makes the swap-out quick, even when the cartridge has been soaking for a few weeks.
Trade Offs
- Not a fit for cartridge systems outside the Intex 59900 family, so the audience is narrow.
- Smaller media area means more frequent rinses on heavy-use pools with lots of swimmers or nearby landscaping.
Who It Suits Best
First-time above-ground pool owners running a matched Intex pump who want a no-fuss, plug-and-play replacement cycle.
Look Elsewhere When
The Yoozell PCC130 Replacement Cartridge 4-Pack is the better match for larger inground systems where a 520 sq ft capacity is the real need.
The three-pack version of the Type A cartridge stretches the same core media into a longer ownership cycle. Where the two-pack above covers a single season with a margin, this set lets you keep a backup on the shelf and rotate through the year without reordering.
Each cartridge carries 13.5 square feet of filtration area, which is meaningful when your pool sits near trees or sees daily cannonballs. Owners commonly report that the Dacron media rinses clean with a garden hose and a soft spray, returning close to original flow after a thorough wash.
Notable Upsides
- Larger 13.5 sq ft area per cartridge captures more debris before flow drops noticeably.
- Three units in the box lower the per-cartridge cost compared with the two-pack format.
- Direct replacement for the Intex 29000E and 59900 series keeps the upgrade path simple.
- Reusable construction means less waste in the trash bin over a typical pool season.
Honest Caveats
- Stocking three cartridges at once takes up a fair amount of shed or garage space.
- Still limited to Intex-compatible pump systems, so it is not a universal swap.
Made For
Above-ground pool households who go through a cartridge every few weeks and prefer to buy in bulk once per season.
Where Another Pick Suits Better
The Aumzong 60 Sq Ft DE Pool Filter Grids suit Hayward DE owners who run a diatomaceous earth system rather than a cartridge pump.
Stepping into DE territory, this Aumzong set is a full grid replacement rather than a single cartridge. DE, short for diatomaceous earth, is a fine powder that coats these fabric grids and traps particles down to a few microns, which is why serious pool owners gravitate toward it.
The 60 square foot total area with 30-inch grid length matches Hayward Pro-Grid DE6020 and Micro-Clear DE6000 housings, plus Unicel FG1005 and several Pentair and Pac Fab references. That cross-compatibility is the real story, because finding an exact match for an older DE system can otherwise turn into a parts chase.
What Stands Out
- Cross-fits Hayward, Unicel, Pentair, Pac Fab, and other common DE housings, simplifying sourcing.
- Full 60 sq ft grid area supports strong flow and fine particle capture during heavy swim weeks.
- 30-inch grid length is a common DE size, so handling and reassembly stay manageable.
Points To Note
- DE systems require periodic recharging with fresh DE powder, which adds an extra step to routine maintenance.
- Not the right match for cartridge-only pools, since the housing and manifold layout differ.
Right Fit For
Hayward DE owners with worn grids who want a complete refresh rather than spot repairs on individual panels.
Consider Something Else When
The Yoozell YZ688E System 3 Cartridges are a stronger fit for large inground cartridge systems that need a 300 sq ft total media area.
Feature Snapshot
This pick is a different kind of problem solver. The Pentair 270141 is a push-pull valve and pump union combination, the hardware that lets you isolate the pump for service or winterizing without draining the whole system.
It is not a filter cartridge or DE grid at all, but it shows up on the same maintenance list, so it earns a spot here. The brass and polymer construction handles the back-and-forth of seasonal work without binding, and the union fitting means hand tools are usually enough to swap the pump out when the time comes.
Practical Advantages
- Combines a shutoff valve and union fitting in one assembly, so the parts count drops.
- Branded Pentair hardware, which keeps the spec match clean for Pentair pump installations.
- Simplifies winterizing, since you can close the valve and drain just the pump side.
Small Caveats
- Not a filtration product, so it does not directly improve water clarity on its own.
- Designed for Pentair system layouts, so mismatched plumbing may need adapters.
Who Will Love This
DIY maintainers working on a Pentair pump who want service-friendly plumbing without a full rework.
A Better Fit Elsewhere
The Yoozell PCC105 Replacement Cartridge 4-Pack serves shoppers who actually need new filter media rather than service hardware.
Quick Facts
Move up in pool size and the filter media needs to grow with it. The Yoozell PCC130 set covers the Clean and Clear Plus 520 housing and crosses to Unicel C-7472, Filbur FC-1978, and Pentair CCP520 references, so a four-pack covers a full year of cartridge swaps for many inground households.
The trilobal fabric is the headline feature. Trilobal fibers have a three-sided cross-section that creates more surface area than round fibers, so the cartridge catches more particles before flow starts to drop. In a busy pool, that translates to longer intervals between rinses.
Points In Its Favor
- Trilobal fabric holds more debris per square inch than standard spun media, based on the material spec.
- Four-cartridge pack spreads the cost across a long stretch of pool ownership.
- Cross-compatibility with multiple OEM numbers reduces the risk of a wrong fit.
Practical Considerations
- Physical size is significant, so storage space for four spare cartridges needs planning.
- Higher media density can mean longer dry times after rinsing, especially in shaded equipment pads.
Best Suited To
Inground pool owners with Clean and Clear Plus 520 systems who run the filter often and want fewer mid-season orders.
Reach For A Different Pick When
The Yoozell 85 Sq Ft Pool Filter Cartridge 4-Pack fits smaller cartridge housings that need a longer, slimmer cell.
Key Product Details
The PCC105 sits between the Intex cartridges and the larger PCC130, sized at 105 square feet per cell. That middle position makes it a common cross-fit for Pentair Clean and Clear Plus 420 systems, Waterway 817-0106 references, and Filbur FC-1977 or FC-6470 swaps.
Where the PCC130 above pushes higher capacity, this set gives smaller inground pools and spas a more proportionate media area. The four-pack format keeps the per-cartridge cost down, which is helpful if you prefer to swap on a fixed schedule rather than waiting for a pressure drop.
What Earns Its Place
- 105 sq ft per cell is a common footprint, so the swap is rarely complicated.
- Fits both Pentair and Waterway references, expanding the audience beyond a single brand.
- Four-pack supports a year of routine maintenance without reordering.
Less Ideal Details
- Not the right capacity for larger 520 sq ft housings, so the PCC130 set is the better fit there.
- Cleaning intervals shorten in pools with heavy debris loads, since the media area is moderate.
Whose Shelf It Belongs On
Owners of mid-size cartridge systems who want a balanced capacity and a budget-friendly four-pack option.
Swap It Out When
The Yoozell PCC130 Replacement Cartridge 4-Pack is the right step up for Clean and Clear Plus 520 housings that need a 520 sq ft cell.
Large inground pools often run a paired inner and outer cartridge arrangement, and the YZ688E set is built exactly for that. The pair delivers 300 square feet of total media, with a 200 sq ft outer at 18-3/4 by 16-1/2 inches and a 100 sq ft inner at 25-1/4 by 8-3/4 inches.
The trilobal fabric carries the same capture story as the PCC130 above, but the larger combined area means longer run times between cleanings. An included O-ring is a thoughtful touch, since the old seal is the kind of part that often gets left behind during a swap.
Where It Delivers
- 300 sq ft total area supports strong flow for bigger inground pools.
- Matched inner and outer geometry simplifies the swap into a single coordinated purchase.
- Trilobal media holds more contaminants per square inch than standard fabric.
- Included O-ring helps prevent the common leak that follows a missed seal.
Possible Compromises
- Larger housings require more clearance to pull and reinstall the cartridges, so pad layout matters.
- Higher upfront cost than smaller cartridge packs, though the per-swap media area is greater.
Who Should Grab It
Owners of larger inground cartridge systems, including Pentair System 3 references, who want a coordinated replacement rather than a single cell.
Skip It When
The Yoozell PCC130 Replacement Cartridge 4-Pack is the right call for Clean and Clear Plus 520 housings that use a single large cell.
Wrapping the list with a long, slim profile, the Yoozell 85 sq ft cartridge measures 27 inches in length with a 7-inch outer diameter and 3-inch openings on both ends. That footprint lands squarely in the compact cartridge housing category, where real estate inside the filter is limited.
Cross-compatibility is broad, covering Unicel C-7459, Filbur FC-6405 and FC-0800, Aladdin 18504, APCC7352, and several Pure N Clean references. The four-pack format keeps the per-cartridge cost manageable for a part that wears out on a regular cycle.
Everyday Perks
- 27-inch length fits compact housings that larger cartridges cannot enter.
- Broad OEM cross-reference list lowers the chance of an ordering mismatch.
- Four-pack reduces annual replacement spend for routine maintenance schedules.
Worth Bearing In Mind
- 85 sq ft is on the smaller side, so rinse intervals stay frequent in heavy-use pools.
- 3-inch open ends need to match the housing manifold exactly, so a quick visual check before ordering pays off.
Perfect Match For
Shoppers with compact cartridge pools who need a long-format replacement on a steady annual cycle.
Another Choice May Suit
The Yoozell PCC105 Replacement Cartridge 4-Pack serves those who need a 105 sq ft cell with a different dimensional profile.
Feature Overview
What Matters Most Before Choosing Filter Grids for Swimming Pool
Match The Filter Type First
The fastest way to end up with the wrong part is to skip the filter type. Cartridge, sand, and DE systems all use different media, and a DE grid cannot drop into a cartridge housing. Check the housing label or the existing part number before anything else, since every other decision flows from that match.
Size Up The Media Area
Filtration area, measured in square feet, is the single biggest driver of cleaning intervals. A 500+ sq ft total setup in an inground pool can run for months between rinses, while a 100 sq ft cell in a busy above-ground pool may need attention every few weeks. Bigger is not always necessary, but undersized media in a large pool leads to pressure spikes and short cycles.
Read The Cross-Reference Numbers
OEM numbers like Unicel, Filbur, and Pentair references act as a universal translator between brands. A single cartridge can replace half a dozen part numbers across manufacturers, which is helpful when the original equipment brand is no longer stocked. Keep the existing label handy when you shop so the cross-reference comparison is quick.
Plan For Maintenance Rhythm
Reusable media keeps long-term cost down, but it does shift work to you. Rinsing, drying, and rotating cartridges takes a corner of the equipment pad and a few minutes per swap. Build that habit into the calendar early, and the water stays clearer with less chemical correction later.
Key Considerations Across These Picks
Mistakes Worth Dodging
Buying by image alone is a common trap, since two cartridges with the same outside diameter can have totally different end fitting sizes. Always compare the OEM part number or the spec sheet, and confirm the height, diameter, and opening size before clicking through. The other frequent slip is ordering one cartridge when the housing actually takes a paired set, which the System 3 style above illustrates well.
The Upgrade Payoff
Stepping from a basic cartridge to a higher-capacity set with trilobal fabric does cost more up front, but the trade-off shows up in longer intervals between rinses and steadier water clarity during peak swim weeks. For larger pools or households that run the filter daily, that difference is easy to feel across a single season and tends to justify the extra spend.
Frequently Asked Questions
How often should pool filter grids or cartridges be replaced?
Most residential cartridges and DE grids last one to two seasons with regular rinsing, though heavy debris loads or poor water chemistry can shorten that window. Replace media when rinsing no longer restores flow or when the fabric starts to fray at the pleats.
Can DE grids be washed and reused like cartridges?
Yes, DE grids are designed for periodic rinsing and recharging with fresh DE powder. Hosing the grids down removes the spent powder, and a new coat is added during the next pump cycle. Avoid high-pressure washes, since they can damage the fabric.
What is trilobal fabric and why does it matter?
Trilobal fabric is made from fibers with a three-sided cross-section, which creates more surface area than round fibers. That extra area catches more particles per square inch, so the cartridge holds more debris before flow drops and the rinse interval stretches out.
How do I confirm a cartridge fits my filter housing?
Match the OEM part number on the existing cartridge or the housing label against the replacement’s cross-reference list. If the numbers align and the height, diameter, and end openings match, the fit is correct.
Is a multi-pack actually cheaper than buying singles?
In most cases, yes. Multi-packs spread the packaging and shipping cost across several cartridges, and the per-unit cost typically drops. The trade-off is upfront spend and storage space for the spares.
