INTEX 29003E Type A Pool Filter Cartridge
Best for: INTEX Krystal Clear filter pump owners who want straightforward maintenance and reliable filtration.
This Type A cartridge uses easy-to-clean Dacron paper to deliver efficient filtration for INTEX pumps such as 28603EG, 28637EG, and 28635EG. The cartridge is designed for routine use with a recommended replacement every two weeks to maintain clear water and steady flow. The packaging emphasizes convenient maintenance and compatibility with common INTEX filter pumps.
Why selected: It directly supports INTEX systems, making it the best choice for owners who already rely on INTEX-pump configurations and want predictable replacement intervals. If your pump is not one of the listed models, consider a universal option.
Caution: Over time, frequent use may wear the Dacron media; monitor water clarity and replace as needed.
U.S. Pool Supply 4 Pack Of Universal Filter Cartridges
Best for: Pool owners seeking a universal, multi-pump compatibility option at a good price.
These four premium cartridges fit above-ground pools using Type A or C filters, and also work with Type III filters. They replace popular models like Intex 59900E and 29000E and are built with advanced filtration fibers for solid water clarity. The pack suits pumps ranging from around 530 to 2,000 gallons per hour, and the filters are washable and reusable, supporting longer service life with biweekly replacement guidance.
Why selected: The pack provides broad compatibility and cost efficiency for households with multiple or changing pump setups. Choose this if you have varying pump models or want a universal solution.
Caution: Verify your pump’s filter type and size before purchasing to ensure a proper fit.
POOLPURE Type A/C / III Pool Filter Replaces Intex 29000E
Best for: Pool owners who want a reusable, durable option with enhanced filtration fabric.
This 2-pack replaces several Intex models and fits a wide range of pump configurations. It features trilobal filtration fabric for higher surface area and three-time dirt adsorption, along with patented dirt-locking technology to ease cleaning. The cartridges are designed to be rinsed and reused, offering cost savings and reduced waste over disposable filters.
Why selected: The trilobal fabric and dirt-locking design can provide longer intervals between cleanings, making this a practical choice for frequent-use pools.
Caution: Reuse requires proper rinsing and inspection for wear; replace the cartridge if media starts to fray or lose integrity.
ARAGIT 6-Pack Universal Pool Filters
Best for: Shoppers looking for a cost-effective, reusable universal cartridge option.
ARAGIT offers a six-pack designed to replace Type A, Type C, or III filters. It uses two plastic mesh structures with a replaceable inner filter, keeping the hard plastic core intact and preventing collapse. The size (7.87 x 3.94 inches) fits many common above-ground pool pumps. It’s marketed as reusable and economical, with the ability to replace only the filter paper in the middle when needed.
Why selected: The combination of reuse and universal compatibility makes this a practical pick for households with multiple pump types or those who want to minimize ongoing filter costs.
Caution: Confirm the exact model and size before buying, as mis-sizing can affect fit and performance.

Buying Guide
Key purchase considerations for above-ground pool filters include compatibility with your pump model, filter material and durability, and replacement frequency.
- Filter Type and Compatibility: Verify Type A, C, or III compatibility with your pump model. If you have multiple pumps, consider universal cartridges.
- Media and Filtration Technology: Look for media with high surface area and dirt-locking or trilobal fibers for better dirt capture and longer intervals between cleanings.
- Reuse vs. Disposable: Reusable cartridges save ongoing cost and waste but require proper rinsing and periodic replacement of inner paper components.
- Size and Fit: Check dimensions (especially 8×4.2 inches and center-hole diameter) to ensure a secure fit in your filter housing.
- Maintenance Schedule: Most guidelines suggest replacing or cleaning every two weeks for moderate use, more often for heavy use.
