Each kit delivers 48 sq ft of filtration area per grid, helping you maintain clearer water through every swimming season. The package includes a complete set of seven full grids (24" L x 11" W) plus one partial grid (24" L x 9¾" W), designed to fit standard frames and simplify replacement tasks. This thoughtful configuration means you can refresh your filter pack without guessing at compatibility, saving time and minimizing downtime.

What’s in the box

• 7 full grids: 24" L x 11" W, each offering 48 sq ft of filtration area
• 1 partial grid: 24" L x 9¾" W to fill gaps in the grid pack
• Clear labeling and exact sizing guidance for quick on-site checks
• Precise contents that align with common DE filter configurations

Why these grids stand out

Designed for broad compatibility, TOREAD FS-2004 grids work with models such as Unicel FS-2004, PFS2448, Filbur FC-9540, Hayward DE4820 (DEX4800DA), MicroClear DE4800, and MicroClear SS DE4800. The grid system uses Diatomaceous Earth powder to capture fine particles, contributing to improved water clarity. A reinforced ABS core resists warping and corrosion from chlorine or saltwater, while the PET surface cleans quickly with a simple rinse, helping you keep maintenance simple between pool seasons.

• Precision grid design helps prevent DE clumping and supports even distribution for efficient filtration
• Vertical ribs promote uniform DE flow for consistent performance
• Backwash frequency can be reduced relative to standard grids, supporting efficiency gains

Durability, maintenance, and trust

As a proud member of the Pool & Hot Tub Alliance, TOREAD aligns with industry standards for filtration performance and safety. The grids feature reinforced ABS cores to resist warping and corrosion, with a PET surface that is easy to rinse clean after use. For best results, a regular maintenance cadence—2 to 4 weeks between cleanings depending on usage—helps keep your system running smoothly without unnecessary downtime.

Real-world use

Imagine weekends spent enjoying a pool that looks consistently clear, thanks to a filtration system designed to handle fine particles with ease. These grids are made to refresh aging DE filters without replacing the entire housing, offering a practical option for improving daily pool care. Results vary by setup, but the combination of precise sizing, durable construction, and easy maintenance creates a compelling upgrade path for many homes.
