About This Item

The Unicel FS-2002 is a complete replacement DE filter grid set engineered for Hayward ProGrid and Pentair FNS / PacFab / American Products 24 square foot diatomaceous earth filter systems. This full 8-grid set — 7 full grids and 1 partial grid — contains everything needed to perform one complete filter re-grid service, built to precise OEM specifications for a proper manifold fit and restored filtration performance.

📦 Complete DE Filter Grid Set — 8 Grids Included
This set includes all grids needed for one complete filter re-grid: 7 full grids (Unicel FG-1002) + 1 partial grid (Unicel FG-1902). One set = one complete filter service.

Note from Unicel: Collar has open slot (2 notches). Length is measured from one end of the grid to the other (collar not included).

⚠️ IMPORTANT: VERIFY COMPATIBILITY BEFORE ORDERING
Match your filter system's OEM part number to the cross-references listed above. The collar's open-slot, 2-notch design must match your filter manifold exactly — if your system uses a different collar configuration, this set will not seat correctly. Confirm your filter model before ordering.

Pro Tips

Always turn off the pump and release all pressure from the filter tank via the air relief valve before opening the tank to replace grids. When measuring your existing grids for verification, measure end to end — do not include the collar length. Inspect the manifold o-ring and collar notches for wear or cracking before reassembling the tank.

About Unicel Filter Cartridges and DE Grids

The "Gold Standard" of Replacement Cartridges
For over 50 years, Unicel (Meissner Mfg.) has been the professional's choice for restoring pool water clarity. While generic "knock-off" filters often use cheap, fuzzy fabric that clogs quickly, Unicel uses genuine Reemay® Filtration Media. This patented synthetic fiber features a unique trilobal shape that traps significantly more dirt and oils without choking your pump's water flow. Based in California, Unicel doesn't just copy filter dimensions; they engineer them to strict Original Equipment Manufacturer (OEM) specifications. This ensures a "lock-tight" fit in your filter tank, preventing debris from bypassing the system and returning to your pool.

Why We Trust Unicel Filter Cartridges and DE Grids
Genuine Reemay® Media: Uses continuous trilobal fibers to capture microscopic debris without restricting water flow.

Precision "Exact Fit": Engineered to match your tank's original specifications for a 100% leak-free seal.

Made in the USA: Manufactured in California with heavy-duty urethane end caps that resist cracking under pressure.

Longer Lifespan: Sharp, rigid pleats resist collapsing during cleaning, meaning you buy fewer replacements over time.
