OEM & Aftermarket Options Available

Keep your water crystal clear with replacement filter cartridges for all major pool and hot tub brands. We carry a wide selection of OEM (original manufacturer) filters and high-quality aftermarket cartridges, giving you flexible options to match your system, budget, and performance needs.

Designed to trap dirt, debris, oils, and fine particles, our filter cartridges help improve water clarity, extend equipment life, and reduce chemical usage. Whether you need a factory-original replacement or a compatible aftermarket filter built to meet or exceed OEM specifications, PTL Direct has the right fit.

Our cartridges are compatible with popular brands including Hayward®, Pentair®, Jacuzzi®, Pleatco®, Unicel®, Waterway®, Sundance®, Caldera®, Master Spas®, and many more. Each filter is manufactured using durable end caps, reinforced cores, and precision-pleated media for reliable flow and long service life.

OEM vs Aftermarket – What’s the Difference?

• OEM filters are produced by the original manufacturer for an exact factory match

• Aftermarket filters are designed to fit and perform like OEM, often at a lower cost

• Both options are available in multiple micron ratings, lengths, and diameters
