A kiddie pool turns a backyard into a five-minute vacation, and the water only stays clear when the filter cartridge inside the pump actually does its job. Skip that step and the water clouds up, the pump strains, and bath time turns into a gritty mess. The picks below are all the cartridge-style filters that work with the small Intex-style pumps most parents already own, so swapping in the right replacement is a two-minute job that keeps summer running smoothly.
A Snapshot Of The Selections
Intex 29011E Type S1 PureSpa Filter Replacement Cartridges (6-Pack)
INTEX 29002E Type A Pool Filter Cartridge (Two Pack)
INTEX Type A Pool Filter Cartridge for Above Ground Pools, 6-Pack
Intex 29000E Type A Pool Filter Cartridge (Single Pack)

Meet The Standout Selections
The Type S1 cartridge is the dedicated replacement for Intex PureSpa portable hot tubs, sized to fit the unique housing that the inflatable spa line uses. Six cartridges arrive in a single box, which covers a full season of weekly rinsing and monthly swaps without another shopping run.
For most parents running a small inflatable spa with a child nearby, the S1 keeps the bubble and massage function running at the flow rate the pump expects. Compared to the standard Type A cartridges below, the S1 is built for higher-temperature water, so the pleats hold their shape longer under spa conditions.
A Favorable Mix
- Multi-pack of six covers a full warm-weather season
- Heavy-duty Dacron paper handles spa temperatures without softening
- Rinses clean under a garden hose for reuse between changes
- Dedicated sizing means a snug fit in PureSpa housings
- Original-spec design for the popular Intex portable spa line
Honest Caveats
- Built specifically for PureSpa models, not for general kiddie pool pumps
- Monthly swap recommended, so plan a small stockpile
Made For
Households running an Intex PureSpa inflatable hot tub who want a season’s worth of replacements in a single order.
Reach For A Different Pick When
You run a standard kiddie pool with a Type A filter pump, where the INTEX 29002E two-pack is the better match.
The 29002E is the standard Type A replacement that fits the small Intex filter pumps most parents pair with kiddie pools. Two cartridges come per pack, which lines up with the routine rinse-and-replace schedule Intex recommends for typical backyard use.
In our view, this is the cartridge you reach for first when an old filter needs to be swapped before the weekend. It works with the 28603EG, 28637EG, and 28635EG pump models, so checking the label on your pump housing confirms fit in a second.
Notable Gains
- Direct fit for the most common Intex filter pumps
- Dacron paper media rinses clean with a hose, no chemicals needed
- Two-pack gives a spare on hand for unexpected swaps
- Lightweight design that doesn’t drag down pump flow
Trade-Offs To Consider
- Only two cartridges per order, so reorders are common mid-summer
- Not compatible with Type B housings found on Easy Set models
Right Fit For
First-time pool owners who want a small, no-fuss starter pack for a Type A pump setup.
Swap It Out When
You run an Easy Set pool, in which case the Intex 29005E Type B two-pack lines up with the housing.
This six-pack is the long-haul option for parents who set up the kiddie pool the moment school lets out and pack it away after Labor Day. With 13.5 square feet of polyester fiber across each cartridge, the media holds enough fine debris to keep cloudy water from becoming the summer default.
It’s the same Type A profile as the two-pack above, just at a quantity that matches real-world use. You may find the larger pack saves a reorder run when the pool sees daily splash sessions through July and August.
Advantages To Know
- Six cartridges cover a typical full season with weekly rinses
- 13.5 sq ft of filter media per cartridge for longer service life
- Direct replacement for the Intex 29000E and 59900 system
Worth Bearing In Mind
- Larger box needs a dry storage spot indoors between swaps
- Same Type A fit only, so Easy Set owners need a different cartridge
Key Product Details
Who Should Grab It
Families with above-ground pools who want one purchase to handle the entire summer without reordering.
A Better Fit Elsewhere
Parents running a PureSpa inflatable hot tub should choose the Intex 29011E Type S1 six-pack for proper fit.
The single-pack 29000E is the original Type A cartridge that started this category for Intex pumps. One cartridge per order suits someone testing whether a new pump setup works before committing to a multi-pack, or anyone whose pool only sees weekend use.
It shares the Dacron paper media and 13.5-square-foot construction with the larger packs above. For most light-use backyards, a single cartridge and a rinse routine covers the gap before the next swap.
Points In Its Favor
- Lowest commitment for first-time pool owners
- Dacron paper media is easy to rinse and reuse
- Fits the same pumps as the multi-packs above
Things To Consider
- One cartridge means a quick reorder once the first one wears out
- Per-cartridge cost is higher than the larger packs
- Not a fit for Type B Easy Set housings
- Weekly rinsing is needed to keep flow strong in heavy-use pools
Best Suited To
First-time filter shoppers who want a single cartridge to confirm the fit before stocking up.
Not Your Match When
You know you’ll need multiple swaps through the season, where the 3-pack or 6-pack options save reorders.
The three-pack splits the difference between a one-off cartridge and a full-season supply. For a typical backyard kiddie pool that runs most afternoons from June through August, three cartridges comfortably cover the rotation with a rinse-and-replace habit.
It uses the same Dacron media and 13.5-square-foot build as the larger pack above. You may find the smaller count easier to store in a garage shelf without dedicating a full bin to filters.
Strengths Worth Knowing
- Three cartridges match a mid-summer rotation without overbuying
- 13.5 sq ft of Dacron media holds fine debris well
- Standard Type A replacement for Intex 29000E pumps
- Compact pack size stores easily in a garage or shed
Points To Keep In Mind
- Heavy daily use may burn through three cartridges before the season ends
- Type A only, so Easy Set and PureSpa owners need other picks
Who Will Love This
Families running a small above-ground pool on a regular but not daily schedule through the warmer months.
Consider Something Else When
You run a PureSpa inflatable spa, where the Intex 29011E Type S1 cartridges are the correct match for the housing.
The 29005E is the Type B replacement built specifically for Intex Easy Set pools, the inflatable ring-top design that fills up with a garden hose. Easy Set pools use a taller, narrower housing than Type A, and forcing the wrong cartridge into it won’t seat properly.
Each cartridge carries 13.5 square feet of Dacron filament media arranged in 63 pleats, which gives the water plenty of contact area as it passes through. In most backyards, the two-pack covers a full month of regular use before the next order.
The Practical Payoff
- Correct Type B fit for Easy Set pool housings
- 63 pleats per cartridge increase debris-holding capacity
- Thicker Dacron paper handles daily rinse cycles well
- 5.75 x 10 inch footprint matches the standard Easy Set slot
Worth Noting
- Two-week replacement recommended for peak pump performance
- Will not seat in a Type A pump housing
Feature Snapshot
Built With In Mind
Owners of Intex Easy Set inflatable pools who need a Type B cartridge that drops into the housing without modification.
Look Elsewhere When
Your pump takes Type A cartridges, in which case the INTEX 29002E two-pack is the more accurate replacement.
POOLPURE earns a spot because the same cartridge covers Type A and Type C/III housings, which helps households that have moved between pump models over the years. The 8 x 4.2 inch footprint slots into the same slots as the Intex 29000E and 59900 systems.
Compatibility with a long list of pump models (28603EG, 28637EG, 28635EG, 28671EG, plus the 58603E and 56635E series) makes this a safe buy when the original packaging is long gone. For most mixed-pump households, that flexibility avoids the trial-and-error of ordering the wrong Type.
Benefits That Matter
- Cross-type fit covers Type A and Type C/III housings
- Works with Krystal Klear 02 and 12R pump models
- Replaces the Intex 29003E, 29000E, and 59900 cartridges
- Compact size for easy storage between swaps
- Third-party option for households with multiple Intex pumps
Points To Note
- Third-party brand, so packaging and finish may differ from OEM Intex
- Not a fit for Type B Easy Set housings or Type S1 spa cartridges
Feature Rundown
Whose Shelf It Belongs On
Households with several Intex pumps or a single pump whose model number is hard to track down.
Where Another Pick Suits Better
Easy Set pool owners should still choose the Intex 29005E Type B cartridge, which is sized for that specific housing.
What Matters Most Before Choosing filters for kiddie pool
Match The Cartridge To The Pump Type
Every Intex-style filter pump takes one of a few cartridge profiles, and the wrong one simply won’t seat in the housing. Type A fits the 28603EG, 28637EG, and 28635EG pump models that ship with many above-ground pools. Type B is the taller, narrower cartridge designed for Easy Set pools with the inflatable ring top. Type S1 is built for PureSpa hot tubs, and Type C/III covers a handful of larger pump housings.
A glance at the label on the side of the pump housing confirms the right Type in seconds. For most first-time pool owners, getting this step right at the start saves the return-trip hassle later.
Consider Pack Size Against Use Frequency
A single cartridge makes sense for a test run or a pool that only comes out on holidays. A three-pack covers most weekend-and-some-weekday schedules through the warmer months. A six-pack suits daily-use pools where the cartridge gets rinsed and swapped on a tight rotation.
For most families, the larger packs shrink the per-cartridge cost while removing the need to reorder mid-summer. Storage in a dry bin is the only real trade-off.
Look At Media Surface And Pleat Count
Filter cartridges use pleated media to trap debris, and the total surface area tells you how much fine material the cartridge can hold before flow drops. The Dacron paper used across most of these picks has a 13.5-square-foot surface, which is enough for typical backyard use.
Pleat count affects how the water contacts the media, and 63 pleats on the Type B cartridge is on the higher end. Higher pleat counts and larger media area both extend the time between cleanings, which matters in pools that see daily splash sessions.
Plan For Rinsing And Replacement Timing
Rinsing under a garden hose once a week keeps flow strong, and a full swap is recommended every two weeks to two months depending on the model and bather load. Heavy use, dirty feet, and sunscreen residue all shorten cartridge life.
Pool owners with a small dry-storage bin for spares can stock up once and forget about it. Those without much garage space should match pack size to a realistic storage spot rather than the biggest pack on the page.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The most common slip-up is ordering by brand familiarity without confirming the cartridge Type. A Type A cartridge forced into a Type B housing will leak, and a Type S1 won’t fit a Type A pump at all. Another trap is buying a single cartridge for daily-use pools and running out halfway through the season, which forces a rush order at the worst time. Some shoppers also overlook the rinse routine, expecting a cartridge to perform for months without ever hosing it off, and the pump flow drops as a result.
Where The Extra Money Goes
Higher-tier multi-packs spread the per-cartridge cost down while cutting the time spent reordering. Original Intex cartridges tend to fit more snugly out of the box, while third-party options like POOLPURE add cross-type flexibility for households with several pumps. The upgrade really pays off when a household runs more than one pool or rotates between a pool and a spa, where one cartridge type across the whole setup simplifies storage and ordering.
Frequently Asked Questions
How often should a kiddie pool filter cartridge be replaced?
Most cartridges benefit from a swap every two to four weeks during regular use. Heavy daily bather load shortens that window, and a quick rinse once a week keeps flow strong between changes.
Are all Intex filter cartridges interchangeable?
No, the Type A, Type B, Type C/III, and Type S1 cartridges each fit specific pump housings. Checking the label on the side of your pump housing confirms the right match before ordering.
Can these cartridges be rinsed and reused?
Yes, rinsing under a garden hose removes loose debris and extends the cartridge life. Once the pleats stay discolored or flow stays low after rinsing, it’s time for a fresh swap.
What’s the difference between Type A and Type B?
Type A fits standard above-ground pool pumps, and Type B is the taller profile designed for Easy Set pools. Easy Set owners need Type B, and other pools typically need Type A or Type C/III.
Is a third-party cartridge like POOLPURE a safe choice?
POOLPURE lists compatibility with a wide range of Intex pump models, including the 28603EG and 56635E series. Verifying your pump model number against the compatibility list is the easiest way to confirm fit.
