Replace your spa filter with the Hydropool Serenity 4520063 – Red/Blue Spa Filter with Bromine/Chlorine Dispenser 50 sq. ft.
 

 
This screw-in spa filter is designed for Hydropool Serenity spas and includes a built-in dispenser for bromine or chlorine. It helps support proper water filtration while allowing sanitizer to be dispensed directly from the filter, depending on your spa’s water care setup.
 

 
Made with pleated filtration fabric and offering 50 sq. ft. of filtration area, this filter is a practical replacement for a worn, dirty or end-of-life spa cartridge. It is compatible with Hydropool Serenity 2020 and newer models, as well as select Dynasty, Vita and Viking spas. Some models may require adapters.
 

 
This filter also replaces several common filter references, including Pleatco PWW50P3, Unicel 6CH-940 and Filbur FC-0359, making it easier for customers to find the correct replacement cartridge when searching by part number.
 

 
Because this model includes a bromine or chlorine dispenser, it is often recommended to order one 4520063 filter with dispenser and one 4520062 filter without dispenser, depending on your spa’s filter setup.
