100% real photography—no CGI, no modeling. What you see is exactly what you get.Package Contents: 7 Full Grids (24" L x 11" W) + 1 Partial Grid (24" L x 9 3/4" W). Filtration Area: 48 Sq.ft.offers superior large-capacity performance and efficiency.Crystal clear water again Constructed from High-Quality Hard ABS Material combined with a Modified High-Density Nylon Mesh, the filter demonstrates excellent wear resistance. This composition enhances structural stability and durability, while simultaneously improving filtration efficiency. High-Efficiency Performance - The enhanced grid structure prevents DE from agglomerating and ensures its even distribution, thereby reducing hydraulic resistance and maintaining efficient water flow. This contributes to maximizing filtration efficiency while extending the intervals between backwashes. Compatible with DE Pool Filter Models : Hayward Pro-Grid DE4820 (DEX4800DA) , Pentair FNS Plus 48 , Unicel FS-2004 , Jandy DEL/DEV 48 , PFS2448 , Filbur FC-9540 , MicroClear DE4800 , DE480S and MicroClear SS DE4800. This DE Pool Filter Grids provides 48 square feet of filtration area, enabling efficient handling of high water flow rates. It is capable of effectively capturing particles ranging in size from 2 to 5 microns, thereby removing hair, dust, sand, suspended solids, impurities, and organic matter from the water, ensuring consistently clear and clean pool water. Great Value & Performance.
Once you've replaced your old filter with these, you'll notice an immediate improvement in water clarity.
The replacement process is quick and easy, which is always a plus.

It is recommended to clean the grid filter element on a quarterly basis or whenever the pressure gauge indicates a predetermined threshold, in order to ensure optimal performance.

You know when you get a sinking feeling that replacing a pool filter system is going to be a huge cost because the filter is no longer working appropriately and just spitting back the dirt into the inground pool?
However replacing these filters will be the best decision you'll ever make, it easily solves your problem and turn your green pool into clear in a day of pumping.
This was an exact fit to your DE filter at a fraction of the price of a Brand Name unit.


The Enhanced Filter Structure allows for the deep penetration of impurities into the filter pleats during cleaning, effectively restoring the filter to a like-new condition after the process. It is recommended to clean the filter when the pressure gauge reaches the predetermined threshold to fully leverage its performance capabilities.

The upgraded fabric is a bit tighter than the others.
Since DE tends to clump more in spots, the Pressure has substantially dropped as well since switching grids.
The filter's service life is extended, replacement frequency is reduced, and the overall efficiency of the pool's water circulation system is improved.

Want to get 10 years out of them?
Then please plan for a muriatic acid bath at least annually, and pay attention to backwashing and refreshing your DE, plan to do a full hose down at least once during the season. DE is more maintenance than Sand, but creates so much clearer water.
