Cryspool 1004 DE Filter Compatible with FNS Plus 48 - 48 sq ft

In this review the Cryspool 1004 DE filter cartridge is evaluated as a replacement option for owners of FNS Plus 48 and several Jandy-style DE systems. The bottom line: it is a practical, cost-effective replacement for pool owners who need a full 48 sq. ft. filtration area and an easy-to-clean pleated structure. The reviewer found the cartridge installs cleanly, filters well, and is especially appealing if you value straightforward maintenance and a near-original fit without paying OEM prices.

Key Features

• 48 sq. ft. filtration: A full 48 sq. ft. of media provides plenty of surface area to trap fine debris and reduce how often you need to backwash or service the filter.
• 7 full + 1 partial grids: The included seven full grids and one partial grid create the correct stack size to match FNS Plus 48 style housings for consistent flow and sealing.
• Trilobal fiber material: Advanced trilobal fibers increase dirt-holding capacity and longevity compared with common point-bond fabrics.
• Improved cleaning: The fabric structure allows deep penetration of trapped particles so the cartridge rinses back to near-new condition during cleaning cycles.
• Wide compatibility: Designed to fit FNS Plus 48, Jandy DEL/DEV 48, DE4820 and other listed models, making it useful for multiple filter brands and housings.

Who It's For

This cartridge is aimed at pool owners with DE grid style filters that accept a 48 sq. ft. element, especially those replacing worn or damaged grids who want a cost-effective aftermarket option. It suits homeowners who perform regular maintenance and will clean the grids periodically to extend service life.

Those who should look elsewhere include owners of non-compatible housings or users who need exact OEM materials for warranty reasons; while Cryspool lists broad compatibility, the manufacturer name is used only for reference and Cryspool is an independent brand.

Pros & Cons

Pros

• Good filtration area and grid count: the 7 full plus 1 partial layout yields the intended 48 sq. ft. of filter media.
• Easy to clean: the trilobal fabric lets dirt wash out effectively, restoring flow after rinsing.
• Value for money: customers report it is a solid replacement without the premium OEM price.
• Broad fit: compatible with many FNS Plus 48 and Jandy-style models for cross-brand use.

Cons

• Build quality varies: some users find it not as robust as the original OEM grids, so longevity may differ by unit.

Our Verdict

The Cryspool 1004 is a sensible aftermarket choice for owners of FNS Plus 48 and compatible Jandy-style filters who want a 48 sq. ft. cartridge that balances cleaning performance and cost. It filters well and rinses clean, offering good value if you maintain the grids regularly; however, buyers seeking identical OEM durability should weigh that trade-off.

Frequently Asked Questions

Will this fit my FNS Plus 48 housing?

How often should I clean the cartridges?
Clean when your pressure gauge reaches the predetermined service value; regular rinsing restores flow because the trilobal fabric sheds trapped particles effectively.

Is this an OEM part?
