Regular cartridge replacement—every two weeks in typical use—helps sustain performance and prolong pump life.
INTEX 29003E Type A Pool Filter Cartridge
This three-pack of Intex Type A cartridges offers convenient maintenance for Krystal Clear pumps. Built with easy-to-clean Dacron paper, these filters are designed for efficient filtration while remaining simple to replace. Compatibility spans several Intex pump models (28603EG, 28637EG, 28635EG), making them a practical choice for ongoing pool care. As with other cartridge systems, routine replacement every two weeks supports optimal flow and water quality.
KGC Type I Pool Filter Cartridge
The KGC Type I cartridge measures 3.1 x 3.5 inches, fitting multiple Summer Waves and similar-pump configurations. Its trilobal fabric and one-piece molding enhance filtration performance, efficiently trapping sediment, leaves, hair, and sunscreen residues. The cartridge is designed for easy cleaning—deep impurity penetration is supported by the filtration pleats—allowing a return to near-new efficiency after rinsing every two weeks.
U.S. Pool Supply 4 Pack Universal Cartridges
This 4-pack provides universal compatibility with many above-ground pool pumps accepting Type A/C and Type III cartridges. Made from premium PET fibers, these cartridges aim to deliver clear-water filtration and feature a durable inner core to resist collapse at pump flow rates from 530 to 2,000 GPH. Routine every-two-weeks replacement is recommended for best results, with wash-and-reuse possible in many setups.

The POOLPURE PLF120A is a compatible option aligned with Hayward, Unicel, and several other brands. Its 23 1/4″ length and 8 15/16″ outer diameter match large cartridge housings, providing substantial filtration area (120 sq ft). The trilobal fabric and layered construction support strong sediment removal and long service life. NSF/ANSI 50 safety certification adds a standard of reliability for household water filters. Regular cleaning and timely replacement maintain peak performance.
Buying Guide
- Compatibility: Verify your pool pump’s filter type (A, C, III, or specific brand models) and cartridge dimensions before purchase to ensure proper fit.
- Filtration media: Look for trilobal fabrics or Dacron filtration media, which balance dirt-holding capacity with rinse efficiency.
- Maintenance interval: Most cartridges perform best with replacements every two weeks during active swimming season; some can be rinsed and reused, extending their service life.
- Size and capacity: Larger cartridges provide more filtration surface, reducing pressure drop and extending cleaning cycles for bigger pools or higher flow pumps.
- Durability: A robust inner core and reinforced end caps improve resistance to collapse and damage under pump pressure.
- Maintenance plan: Having multi-pack options helps maintain an uninterrupted filtration cycle and simplifies scheduling replacements.
- Certifications: NSF/ANSI 50 or similar safety standards indicate material safety for contact with drinking water or pool water.
- Cost vs. lifespan: Compare initial price with expected service life and cleaning efficiency to determine best value per season.
