Poolzilla Pool Filter Cartridges 4-Pack 27 x 7 in Replacement for Unicel C-7459, Pleated Synthetic, Easy-Install

Poolzilla 4-pack replacement filter cartridges (27" x 7" OD) are direct-fit pleated filters engineered to replace Unicel C-7459 and compatible models for clearer pool water and reliable circulation.

These Poolzilla cartridges are made to be a straightforward swap for several common OEM part numbers so you can restore filtration performance without buying a new tank. Each pack contains four identical pleated filters sized 27 inches long by 7 inches outer diameter, built from durable synthetic media that resists tearing and holds pleat shape through repeated cleanings. Designed for residential and light-commercial pools, these cartridges emphasize easy maintenance, strong debris capture, and consistent flow as the pleats age.

How do these cartridges restore water clarity?

Poolzilla cartridges trap visible particles and finer sediment within densely folded pleats, removing sand, silt, algae fragments, and rust particulates from circulating water. The media’s surface area captures contaminants while allowing steady flow to reduce strain on the pump.

• Pleated synthetic fabric increases filtration surface area for higher dirt-holding capacity.
• Compatible with Unicel C-7459, Jandy CL 340, Filbur FC-6405 and other OEMs for easy replacement.
• Regular rinsing restores flow and extends useful life to roughly 1–2 years with typical maintenance.

Will these fit my filter assembly and how easy is installation?

These cartridges match the common dimensions and end fittings of the listed OEM models so installation is a simple pull-and-replace operation for most cartridge-style housings. No special tools are required—just remove the old element, rinse the housing, and seat the new cartridge evenly to prevent bypass.

• Dimensions: 27" length x 7" outer diameter—designed for a direct fit into compatible housings.
• Four cartridges per pack for multi-filter systems or staged replacements.
• Snap-in fit and standard end caps replicate original cartridge geometry for reliable sealing.

How do I clean and maintain these filters to maximize lifespan?

Maintenance is primarily rinse-and-inspect: remove loose debris with a hose, inspect pleats for damage, and soak in a cartridge cleaner for stubborn oils or scale. Proper seasonal storage and avoiding harsh scraping preserve pleat integrity and keep flow consistent.

• Rinse with a garden hose after every heavy debris event or weekly during peak season.
• Use a dedicated filter cleaner soak monthly for best performance in bather-heavy pools.
• Replace after 1–2 years depending on usage, chemistry balance, and visible wear.

What contaminants will these cartridges reduce?

Poolzilla cartridges are optimized for mechanical removal of common pool contaminants rather than chemical disinfection. They effectively reduce suspended solids and particles that cause cloudiness and can help lower off-tastes and odors by removing particulate-bound chlorine byproducts.

• Removes sediment, sand, silt, and rust particles for clearer water.
• Captures organic debris like leaves and algae fragments before they contribute to cloudiness.
• Supports overall sanitizer efficiency by clearing particulate load on circulation.

Who is this for: Pool owners and service professionals who need a dependable, cost-effective replacement for Unicel C-7459 and related cartridge models will appreciate this Poolzilla 4-pack. It’s particularly useful for multi-filter setups, seasonal top-ups, or operators who prefer routine cartridge swaps to maintain steady circulation and water clarity without redoing plumbing or housings. If you manage a residential pool and want a durable, easy-to-clean cartridge that matches common OEM specs, this package offers immediate compatibility and the spare parts needed to keep your system running smoothly all season long.
