Unicel 48 Sq Ft Partial DE Filter Grid Replacement
Restore Your Pool’s Filtration Performance with a Trusted Replacement Grid
Diatomaceous earth (DE) filters are known for delivering some of the clearest water possible, but their performance depends on high-quality grids inside the filter tank. Over time, factory grids can clog, tear, or break down, reducing efficiency and leaving water cloudy. That’s why pool owners and service professionals trust Unicel 48 Sq Ft Partial DE Filter Grid Replacements—a dependable, OEM-quality solution engineered with durable Reemay® filtration fabric for long-lasting performance.
Designed to fit DE filter systems with a 48 sq ft grid set, this partial grid replacement is built to match or exceed OEM specifications, giving you peace of mind and cleaner water with every cycle.
Why Replace Your DE Filter Grids?
DE filters use a set of full and partial grids coated with diatomaceous earth powder to capture microscopic debris. Over time, however, grids deteriorate due to:
-
Chemical exposure (chlorine, shock, algaecides)
-
High pressure during filtration cycles
-
Wear and tear from backwashing and cleaning
-
Organic debris clogging the fabric
When a grid rips, water bypasses filtration, allowing dirt and algae spores to recirculate. Replacing worn or broken grids ensures that your DE filter continues performing at its peak, keeping your pool water sparkling clear.

Full vs. Partial Grids: What’s the Difference?
A typical 48 sq ft DE filter contains 7 full grids and 1 partial grid. The partial grid is slightly smaller and sits alongside the full grids inside the filter manifold. If just one partial grid fails, you don’t need to replace the entire set—simply swap it with a Unicel replacement for reliable performance at a lower cost.
