Grefilt Type B Pool Filter Cartridges 6-Pack — Compatible with Intex 29005E, Trilobal High-Flow

Grefilt 6-Pack Type B Pool Filter Cartridges are compatible replacement filters designed to trap dirt and debris so your above-ground pool water stays clearer between cleanings.

These cartridges are made as a direct-fit replacement for many Type B pool filter systems, including models that reference Intex 29005E and pumps rated around 2500 GPH. Constructed with a high-performance trilobal filtration fabric and reinforced end caps, the six-pack gives you multiple spares to rotate, clean, and swap as needed. They meet NSF/ANSI 50 testing standards for materials used in pool equipment, offering a confident choice when refreshing worn or clogged cartridges.

How do these cartridges improve pool water clarity?

Each cartridge uses a multi-layer trilobal fabric that increases surface area and captures fine particles that ordinary filters can miss. With more filtration area, the pump cycles fewer large debris clogs and the water clears faster after normal use or seasonal opening.

• Trilobal filtration fabric for increased dirt-holding capacity
• Multiple pleats boost surface area compared with flat media
• Reduces visible debris and extends time between cleanings

Are these filters easy to install and maintain?

Yes — the cartridges are designed to slide into the common Type B filter housings without special tools, so replacement takes only a few minutes. Cleaning is straightforward: rinse with a hose or soak periodically to remove oils and fine particles, then reinstall when dry.

• Tool-free installation fits standard Type B housings
• Simple rinse or soak cleaning extends cartridge life
• Six cartridges provide rotation for drying and longer service life

What materials and certifications should I expect?

These cartridges use reinforced polyester fibers and corrosion-resistant end caps that hold pleats firmly in place during pump cycles. Grefilt has had the product tested against NSF/ANSI 50 material requirements, confirming the components are suitable for use in pool equipment.

• Reinforced polyester pleats for durability and shape retention
• Corrosion-resistant end caps withstand outdoor conditions
• Tested to NSF/ANSI 50 material standards for safety of components

Which pool systems are these compatible with?

The Type B cartridges are intended as compatible replacements for a range of above-ground pool pumps that list Type B or part number equivalents like Intex 29005E. Always check your pump or filter housing model before purchasing to confirm fit.

• Compatible with many above-ground Type B filter housings
• Common fit for pumps around the 2500 GPH range when specified
• Manufacturer names used for reference — verify your model for exact fit
