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.
