Keep your water cleaner with the Pleatco PBF36 Filter Cartridge - 35 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.
 
The Pleatco PBF36 is a practical replacement option when your current filter is worn, damaged, saturated or no longer cleaning effectively. It is commonly used for select Bullfrog 35 spas, especially 2013 to 2017 models using a long-thread modified ACME bottom connection.
 
Before purchasing, always verify your current filter’s dimensions, including length, outside diameter, handle top and bottom thread style.
