Pentair D.E. Filter Cartridge 120

The term Pentair D.E. Filter Cartridge 120 can refer to two separate components depending on your specific pool equipment setup: the large replacement cartridge element for the advanced FullFloXF® Q120 High-Efficiency Cartridge D.E. Filter (System SKU #188616), or a replacement cartridge element pack for a large-capacity Quad D.E.® 100 system configured with aftermarket element options.

Functional Overview

Unlike traditional D.E. filters that use flat, fabric-wrapped fiber grids stitched onto rigid frames, these cartridge-style elements utilize pleated, heavy-duty polyester media. The pleated pattern significantly packs more usable surface area into a smaller physical space. When coated with Diatomaceous Earth (D.E.) powder, the water passes smoothly through the pleats while capturing microscopic debris down to 3 to 5 microns. This unique design provides the unmatched micro-filtration clarity of a classic D.E. system alongside the simple, low-maintenance wash-and-rinse routine of a standard cartridge filter.

Weight and Shipping Profile

Because these elements feature dense rubber end caps, supportive internal plastic cores, and sprawling square footage of pleated fabric, they have a substantial physical weight footprint:

• Actual Product Weight: Approximately 5.20 to 6.50 pounds per individual element (depending on fabric density and whether it is a single-piece element or part of a multi-pack core).

• Packaged Shipping Weight: Typically scales between 7.5 and 9.0 pounds for an individual replacement unit, or 26.0 to 30.0 pounds when shipped as a complete bundled 4-pack grid nest. This is due to the thick cardboard boxing and internal stabilization columns required to keep the delicate pleats from being crushed or frayed during transit.
