Waterway Plastics Filter Cartridge

This is a direct OEM replacement for Waterway filter systems. To ensure a perfect fit, verify that your current filter housing requires a cartridge with a 7-inch diameter and a 20-inch length.

You should rinse the cartridge with a garden hose whenever your pool's pressure gauge reads 8-10 PSI above the clean starting pressure. Depending on your pool's usage and debris levels, the cartridge typically needs a full replacement every 12 to 18 months.

Yes, this cartridge is designed to be versatile and performs effectively in both in-ground and above-ground pool filtration systems, provided the housing dimensions match the 7-inch by 20-inch specification.

Choosing an OEM (Original Equipment Manufacturer) part ensures the filter media density and dimensions are exactly what the manufacturer intended for your specific system. This guarantees a proper seal and optimal filtration efficiency, preventing debris from bypassing the filter.

The 75 square feet of surface area is engineered to balance high-capacity debris capture with adequate water flow. As long as you keep the pleats clean, this design maintains the necessary circulation to keep your pool water clear without straining your pump.
