Why D.E. Filter Grids Matter
-
Superior Filtration – Capture particles as small as 2–5 microns.
-
Cleaner, Safer Water – Removes algae spores, oils, and fine debris.
-
Efficient Operation – Maintains proper flow and pressure.
-
Extended Filter Life – Keeps tanks, manifolds, and plumbing in better condition.
-
Professional-Level Results – Preferred by commercial pools and service pros.
D.E. filter grids work together with D.E. powder to capture fine particles, while related filter parts, manifolds, O-rings, and air relief assemblies help keep the entire filtration system sealed and operating correctly.
Types of D.E. Filter Grids
1. Full Grids
Use this version:
Full D.E. filter grids are the large panels that make up most of the internal grid assembly. They are commonly used in D.E. pool filters and must be matched to the correct filter size, such as 36 sq ft, 48 sq ft, or 60 sq ft systems.
2. Partial Small Grids
Use this version:
Partial D.E. grids, sometimes called small grids, complete the filter grid assembly and help balance water flow inside the filter tank. When replacing one damaged grid, inspect the matching filter O-rings, manifold, and internal filter parts at the same time.
3. Complete Grid Sets
Use this version:
Complete D.E. grid sets usually include 7 full grids and 1 partial grid. A full replacement set, such as the Unicel FS-2005 60 Sq Ft D.E. filter grid set, is ideal when older grids are stained, brittle, torn, or causing D.E. powder to return to the pool.
4. High-Quality Aftermarket Options
Use this version:
High-quality aftermarket D.E. filter grids can be a cost-effective alternative to OEM grids. Options like Unicel D.E. filter grid replacements are designed to restore filtration performance while helping pool owners avoid replacing the entire filter system.
Signs It’s Time to Replace Your D.E. Grids
If you notice cloudy water, high filter pressure, or D.E. powder blowing back into the pool, your grids may be torn, collapsed, or no longer sealing properly. These symptoms can also point to damaged filter parts, worn filter O-rings, a cracked manifold, or a failing air relief assembly like the Air Relief Valve with Pressure Gauge (SW-26-900) pentair style.
Maintenance Tips for D.E. Grids
Backwash your D.E. filter regularly, recharge it with fresh D.E. powder, and deep clean the grids with a quality pool filter cleaner at least once per season. During cleaning, inspect each grid, manifold, standpipe O-ring, air relief assembly, and other internal pool filter parts for cracks, tears, or wear.

✅ FAQ – D.E. Filter Grids
Q: How often should I replace my D.E. filter grids?
A: On average, every 3–5 years. Heavy use or poor maintenance can shorten their lifespan.
Q: Do I need to replace all grids at once?
A: Not always. If only one grid is damaged, you can replace it individually. However, for older sets, replacing the full set is recommended.
Q: Can I use my filter without D.E. powder?
A: No. D.E. powder is essential for filtration. Grids hold the powder but don’t filter alone.
Q: Are aftermarket D.E. grids as good as OEM?
A: High-quality aftermarket grids often perform just as well at a lower cost.
Q: How do I know what size grid I need?
A: To find the correct D.E. filter grid size, measure the length of your existing grid or check your filter’s model number. Common options include 36 sq ft D.E. grid sets, 48 sq ft D.E. grid sets, and 60 sq ft D.E. grid sets.
Q: Why is D.E. powder returning to my pool?
A: D.E. powder returning to the pool usually means there is a torn D.E. filter grid, cracked manifold, damaged standpipe O-ring, or failed internal filter part. Inspect the grids, manifold, air bleed assembly, and O-rings before recharging the filter with new D.E. powder.
