MXLTYMX 48 Sq. Ft. DE Filter Grids — Replacement Set (7 Full + 1 Partial) for Hayward, Jandy, Pentair

MXLTYMX 48 square-foot diatomaceous earth (DE) filter grid set is a direct-fit replacement pack designed to restore filtration performance in many 48 sq. ft. DE pool filters.

If your DE filter is due for new grids, this MXLTYMX set offers seven full-length grids and one shorter partial grid engineered to match common 48-square-foot cartridges used across Hayward, Jandy, Pentair-related models and other major brands. Built from a micro glass-fiber media and framed to standard dimensions, these grids aim to make swapping worn elements simple while returning surface area for efficient particle capture.

Will these MXLTYMX grids fit my existing 48 sq. ft. DE filter?

These grids are manufactured to the common dimensions used by many 48 square-foot DE filter models and are intended as replacements for PFS2448, Unicel FS-2004 and Filbur FC-9540 style elements. They work with a wide range of housings produced by Hayward, Jandy, Waterway, Pac Fab, Sta-Rite, Astral and several other makes when those models call for a 48 sq. ft. grid set.

• Seven full grids at approximately 24 x 11 inches plus one partial 24 x 9.75 inch grid.
• Compatible with many Hayward Pro-Grid and MicroClear 48 models.
• Fits various Jandy DEV/DEL, Waterway and Pac Fab 48 DE filter models.
• Check your filter model number against manufacturer compatibility lists before purchasing.

How simple is installing and cleaning these replacement grids?

Installation is straightforward for anyone familiar with routine DE filter maintenance: remove the old grids, position the full and partial grids on the center manifold, and reassemble following your filter’s service manual. The micro glass-fiber media sheds debris during backwash and rinses clean with a garden hose, making regular upkeep quick.

• Simple swap-in design mirrors factory grid layout.
• Micro glass-fiber material rinses clean faster than densely packed cloth types.
• Follow manufacturer torque and gasket seating instructions when reassembling.
• Inspect manifold and grid-top seals for wear during replacement.

What performance can I expect after replacing old grids?

Replacing worn or torn DE grids restores the filter’s effective surface area, which helps maintain lower pressure and clearer water between cleanings. While actual results depend on pump flow, DE charge amount and pool conditions, fresh grids typically reduce the frequency of deep cleans and help maintain steady circulation pressure.

• Restored surface area improves particle capture efficiency.
• Can lower operating pressure compared with degraded elements.
• Helps prolong the time between full grid cleanings.
• Use the correct amount of DE powder recommended for your filter model.

Are these MXLTYMX grids durable and safe for my system?

The grids use reinforced framing with glass-fiber media that resists tearing and chemical exposure under normal pool conditions. They are designed for mechanical compatibility rather than being a direct OEM product; routine visual inspection during service will help ensure gasket seals and manifold connections remain leak-free.

• Reinforced top and bottom supports to maintain shape under flow.
• Micro glass-fiber media resists fraying and holds DE coating well.
• Not an OEM-branded part, so confirm physical fit before final assembly.
• Replace any cracked manifold parts or old gaskets when upgrading grids.

Who this is for: Pool owners or service professionals running 48 sq. ft. DE filters who need a full replacement grid kit to regain filtration efficiency. This MXLTYMX set suits those who prefer a ready-made kit (seven full grids plus one partial) to match commonly used 48 sq. ft. filter housings from Hayward, Jandy, Waterway, Sta-Rite, Pac Fab and related brands. Ideal for seasonal overhauls or when grids show ripping, heavy staining, or persistent pressure spikes.
