Rainbow Waterway 50

Keep your spa water clean and clear with the Magnum Filters Rainbow / Waterway 50 Cartridge Filter. This replacement cartridge provides 50 square feet of filtration and suits compatible Rainbow and Waterway top-load spa filter systems. The pleated filter media captures dirt, oils, hair and fine debris from the water, helping maintain clear water and good circulation. The RD50 cartridge measures approximately 338 mm long and 125 mm in diameter. It has a 54 mm open hole at both ends.

Regularly rinse the cartridge to remove trapped debris and maintain water flow. Use a suitable spa filter cleaner for deeper cleaning and to remove oils and build-up.
