Keep your water cleaner with the Pleatco PWW50P3 Filter Cartridge - 50 sq ft.
 

 
This replacement filter is designed to support water filtration by helping capture debris, fine particles, hair, oils and other contaminants that can be found in spa water. A clean, well-maintained filter helps support proper water circulation, better filtration and clearer water.
