PLEATCO ADVANCED – THE NEW STANDARD IN POOL AND SPA FILTRATION. The world’s most advanced scientifically engineered swimming pool and spa filter cartridges and DE grids.

Pleatco's Free Flow Tecnology uses updated technology instead of PVC pipe with holes drilled in them! Pleatco’s cores allow for the even flow of water through the entire cartridge which increases filtration and makes it easier for your pump to move water through the entire cartridge. Pleatco’s Free Flow Cores operate 50% more efficiently saving money, energy, and the environment. PLEATCO DE GRIDS – PERFORMANCE, DURABILITY, EFFICIENCY. Boasting a reinforced center tube, a Pleatco engineered frame and expertly sewn seams – Pleatco’s DE Grids feature an exclusive woven polypropylene which contains only virgin resins to assure the highest strength and to maximize filtration! Pleatco’s “snap-lock” feature keeps the sections from coming apart during filtration when water is in motion. All seams are stitched with a chemical resistant, heavy-duty 4-ply thread.
