Hydropool® Compatible 75 Sq Ft Filter Cartridge – OEM Fit – part #4520008

One-piece, no-core design filter cartridge offering 75 sq ft of pleated filtration media to trap sediment, oils, and particles as fine as 10 microns, ensuring clear, healthy spa water.

Compatible with Hydropool Self‑Cleaning models—AquaSport, AquaTrainer, Executive Sport/Trainer 16EX/19EX, and 19DTAX produced from 2021 to 2025.

Constructed with matching top and bottom ports sized at 2⅛″ (54 mm), simplifying installation without adapters or core assembly.

Compact yet powerful—measuring approximately 20⅛″ long with a 5″ diameter—to fit tight filter housings while maximizing water flow and capacity.

Durable spunbond polyester media resists high-temperature spa environments, chemical exposure, and repeated cleanings to provide extended service life.

No separate core to manage—just rinse weekly and deep clean monthly; replace every 12 months depending on usage to maintain peak performance.

OEM-level construction ensures optimal pump and heater protection by enhancing flow and blocking contaminants effectively.

Ideal for Hydropool spa owners and service techs seeking cost-effective, reliable filtration without sacrificing brand compatibility.
