Unicel 5CH-35 | 35 sq ft Top Load Spa Filter Type_Igniters Use it every time youThe Unicel 5CH 35 is a top load spa filter cartridge delivering 35 square feet of filtration across 203 pleats of Reemay 2033 polyester media. Built to meet or exceed OEM specifications, it's a direct replacement for Elite Spas by Maax, Marquis, and other systems using this cartridge. Filtration is the quiet backbone of clean spa water.
