The Onnfang Reusable Pool Filter Sponge is a mechanical necessity for pool and spa owners looking to optimise their maintenance costs while maintaining high water clarity. Engineered as a high-durability replacement for standard S1 paper cartridges, this sponge acts as a mechanical barrier for capturing debris in Intex Bubble and Jetted Pure-spas. Its washable and reusable architecture acts as a mechanical necessity for reducing long-term overhead, providing a sustainable alternative to disposable paper filters without compromising filtration efficiency.

Key Features

• Integrated "Cost-Reduction" Architecture: Experience a mechanical necessity for economic pool management. While the initial investment is slightly higher than paper, the sponge acts as a mechanical necessity for long-term savings by lasting significantly longer than traditional cartons.

• Supportive "Wash-and-Reuse" Engineering: Achieve effortless maintenance. The sponge material acts as a mechanical necessity for repeated cleaning cycles; simply rinse and reinstall to maintain optimal water throughput.

• Technical "High-Flow" Utility: Designed for efficiency. The open-cell sponge structure acts as a mechanical necessity for maintaining consistent water flow while trapping fine particles, preventing strain on your spa’s pump system.

• Mechanical "S1-Replacement" Design: Engineered as a direct fit. This foam cartridge acts as a mechanical necessity for replacing the S1 carton, fitting perfectly into the standard filter housing of Intex Pure-spas and hot tubs.

• Durable "Compressed-Recovery" Utility: The resilient sponge material acts as a mechanical necessity for durability. Note: If the product arrives compressed, allowing it 2 hours to rest acts as a mechanical necessity for it to recover its full operational shape.
