CPLIKE DE Grid Filter Set 48 Sq.Ft FS-2004 Replacement — 7 Full + 1 Partial, ABS Frames & Nylon Mesh

The CPLIKE FS-2004 48 Sq.Ft DE grid filter set is a direct replacement kit of seven full grids plus one partial grid built to restore high-efficiency diatomaceous-earth filtration for compatible DE pool filters.

When your DE filter performance drops, worn grids reduce flow and clarity. This CPLIKE replacement set is designed to match the 48 sq.ft. grid area used in Unicel FS-2004 and several popular DE housings so you can renew filtration efficiency without buying a new tank. These grids combine a rigid ABS frame with fine, high-density nylon mesh and heavy-duty stitching for durable, repeatable cleaning cycles.

Which filter models will this grid set fit?

This kit is sized specifically for 48 sq.ft. DE systems — confirm your filter model and grid area before purchase. It lists compatibility with Unicel FS-2004 and other common housings, but it is not suitable for 36, 60, or 72 sq.ft. units.

• Compatible: Unicel FS-2004, PFS2448-style, Filbur FC-9540 equivalents.
• Also fits: Hayward Pro-Grid DE4800-series and MicroClear DE4800 variants.
• Not compatible: 36, 60, 72 sq.ft. filters — check label or manual.
• Includes: seven full grids (24" x 11") and one partial grid (24" x 9-3/4").

How does the CPLIKE grid material affect performance and durability?

The frames are molded from hard ABS for impact resistance while the filtration faces use a high-density nylon mesh that traps fine particles. The stitched seams and reinforced fabric help the grids withstand repeated cleanings and handling without sagging or tearing.

• ABS frames: resist cracking and maintain grid shape under pressure.
• Nylon mesh: captures particles in the 2–5 micron range when used with DE powder.
• Heavy-duty stitching: reduces seam failure during maintenance.
• Designed for repeated rinse-and-dry cleaning cycles.

What maintenance and cleaning routine keeps these grids working best?

Routine cleaning preserves flow rate and prolongs grid life. Remove the grids from the tank, rinse debris with a hose, let dry thoroughly, and inspect seams and mesh before reassembly — the manufacturer recommends cleaning about every two weeks under normal conditions.

• Rinse: use a garden hose to wash trapped debris off the mesh.
• Dry: air-dry grids completely to avoid mildew or damage.
• Inspect: check for mesh wear or torn stitching before reuse.
• DE use: pair with medium or coarser DE powder for these fine-mesh grids.

Who is this for: Pool owners, service technicians, or maintenance pros with a 48 sq.ft. DE filter housing looking to restore filtration performance without replacing the entire unit. If your system is listed among the compatible models and you want a cost-effective replacement that balances fine filtration with durable construction, this CPLIKE kit delivers the complete set of grids needed to return your filter to optimal operation.
