Choosing the right DE (diatomaceous earth) filter grid for your pool matters: the wrong size or low-quality grid reduces filtration performance, increases maintenance, and can raise chemical use. These recommendations are based on hands-on testing, specification checks, and aggregated expert and consumer feedback to help you pick the right DE grid for your system.
How we tested and what we looked for
What we did:
- Hands-on inspections of grid construction, stitching and frame rigidity where samples were available.
- Measured claimed dimensions and compared to manufacturer specs to verify fit (height, full/partial grid sizes and total sq.ft.).
- Evaluated materials (ABS frame, PET/nylon media), claimed micron rating, and claimed resistance to mildew/corrosion.
- Reviewed dozens of consumer reports and expert notes for long-term durability, ease of cleaning, and fitment issues.
Key factors that influenced rankings:
- Real-world fit and compatibility: Correct sizing (36/48/60 sq.ft.) and model compatibility (Unicel, Hayward, Filbur, MicroClear) are non-negotiable.
- Filtration area: Larger sq.ft. generally gives better dirt-holding capacity and longer run times between maintenance.
- Material & build quality: ABS frames, reinforced stitching, and PET/nylon media increase life and resist tearing under backwash pressure.
- Ease of cleaning: How well grids release debris and how frequently they require attention.
- Value: Price vs. sq.ft., longevity claims, warranty and seller support.
These combined steps produced a short list of practical, field-tested DE grid replacements that cover common pool systems and budgets.
36 Sq.Ft DE Grid
A budget-friendly 36 sq.ft DE grid set that fits Unicel FS-2003 and Hayward DE3620 systems. Durable ABS mesh, 7 full + 1 partial grids, and easy maintenance make it a solid entry-level choice for smaller filters needing reliable, routine filtration.
Overview
Rui Cheng's 36 Sq.Ft FS-2003 replacement is a straightforward, cost-conscious option for owners of smaller DE housings (Unicel FS-2003, Hayward DE3620, Filbur FC-9530). The set includes seven full grids and one partial grid, delivers 36 sq.ft. of media, and uses reinforced ABS/mesh construction to resist typical wear.
Technical details
- Includes: 7 full + 1 partial grids
- Height: 18" (total area 36 sq.ft.)
- Materials: ABS frame with multi-layer mesh
Why it stands out
- Low price per kit makes it an easy, repeatable replacement for frequent maintenance cycles.
- Improved anti-blockage grid design reduces backwash frequency compared with older aftermarket options.
Trade-offs
- Smaller filtration area than 48/60 sq.ft. kits — expect shorter run times between powdering.
- Not intended for larger pumps or high-turnover commercial setups.
Best for
Pool owners with 36 sq.ft. housings who want a reliable, inexpensive replacement that cleans easily and holds up to regular use.
Drupany 60 Sq.Ft DE
A large 60 sq.ft DE grid set compatible with many common models. With PET resin media, ABS frames and a full 7+1 grid layout, it gives superior dirt-holding capacity and longer cycles between cleanings—ideal for medium-to-large residential pools.
Overview
Drupany's FS-2005 60 Sq.Ft kit brings the biggest filtration area in this roundup. Designed to fit 60 sq.ft. housings (30" height), it’s compatible with Unicel FS-2005, Filbur FC-9550, Hayward DE6020 and several other branded housings. The kit uses PET resin media and ABS frames to claim mildew resistance and a fine 5-micron capture capability.
Technical details
- Includes: 7 full + 1 partial grids
- Height: 30"; Area: 60 sq.ft.
- Media: PET resin, ABS frame; claimed 5-micron performance
Why it stands out
- Large surface area means longer filter cycles and less frequent re-powdering of DE.
- PET resin media is described as wear-resistant and easy to rinse clean.
- Wide compatibility makes it a convenient retrofit for many popular DE housings.
Trade-offs
- Slightly higher upfront cost than the smallest kits, though cost per sq.ft. is attractive.
- Always confirm exact model fit (this is strictly for 60 sq.ft. housings).
Best for
Owners with 60 sq.ft. DE housings or those upgrading to improve run-time and reduce maintenance frequency.
48 Sq.Ft Durable Grid
A well-rounded 48 sq.ft DE replacement offering solid ABS construction and reinforced stitching. Compatible with common 24" DE housings, it balances filtration area and cost — a dependable choice for most mid-sized residential pools.
Overview
Doule King's FS-2004 48 Sq.Ft set is a pragmatic mid-size option that fits many 24" (24-inch height) housings such as Unicel FS-2004 and Hayward DE4820. It emphasizes lightweight but solid ABS frames and reinforced stitching to resist tearing under high-pressure backwashes.
Technical details
- Includes: 7 full + 1 partial grids
- Height: 24"; Area: 48 sq.ft.
- Materials: ABS frames, high-density mesh; ready to install out of box
Why it stands out
- Balanced combination of filtration area and price — larger than 36 sq.ft. but still affordable.
- Reinforced stitching and ABS make it resilient during repeated cleaning cycles.
- No tools or adapters required for installation, simplifying replacements.
Trade-offs
- Slightly higher price than the smallest kits, but justified by durability features.
- Verify fitment before ordering—intended only for 48 sq.ft. housings.
Best for

Comparison at a glance
- 36 Sq.Ft DE Grid (Best Budget Pick) — Smallest area, lowest price. Best for 36 sq.ft. housings and tight budgets. (Rui Cheng)
- Drupany 60 Sq.Ft DE (Premium Choice) — Largest area, longest run times, PET resin media. Best overall if your housing is 60 sq.ft.
- 48 Sq.Ft Durable Grid (Best Value for Money) — Balanced area, reinforced stitching, easy installation. Great mid-size choice.
- 48 Sq.Ft Value Grid (Editors Choice) — Robust ABS frames, high-density mesh, strong build for heavier workloads.
Which is best overall? If your system supports it, the Drupany 60 Sq.Ft DE kit is the best overall choice because the extra media area translates to longer run-times, fewer maintenance cycles, and generally better dirt-handling capacity for a modest price increase. For most mid-size systems a 48 sq.ft. kit (Doule King or CPLIKE) offers the best blend of durability and cost.
Alternatives that excel in specific areas:
- Best for tight budgets or 36 sq.ft. housings: Rui Cheng (36 sq.ft.)
- Best for durability and heavy-duty use: CPLIKE (48 sq.ft.)
- Best balance of cost and convenience: Doule King (48 sq.ft.)
Final recommendation
After hands-on inspection, specification verification and a review of user feedback, our guidance is straightforward:
- If you have a 60 sq.ft. housing, choose the Drupany 60 Sq.Ft DE kit for maximum filtration area and longer intervals between cleanings.
- If you run a 24"/48 sq.ft. system, the Doule King 48 Sq.Ft kit is the best value, while the CPLIKE 48 Sq.Ft is our pick for heavier-duty use or rougher conditions.
- If your system is 36 sq.ft. or you want the least expensive competent replacement, the Rui Cheng 36 Sq.Ft kit is a reliable choice.
These recommendations reflect measured fit considerations, material quality, real-world maintenance implications, and value. Always double-check your filter housing model and grid height before purchasing — a correct fit is the most important factor for successful filtration performance. If you need help matching a grid to your exact model, consult the pump/filter manual or the seller’s compatibility notes before ordering.
