About this item

This big guy has 50 square feet of filter area and will fit many of the spas sold on


Carefully check our size specifications to make sure there's a match with your need. Unlike other filter cartridges manufactured for the pool/spa marketplace, our filter cartridges have endcaps that are 100% antimicrobial. This means our cartridges are more effective in prohibiting the growth of mold, mildew, and odor causing bacteria. A unique modular adapter replaces the typical threaded extensions and allows mounting of the cartridge to the filter housing for top load models.

    How to Identify the Filter Cartridge You Need:
    1) Measure the outside diameter of the cartridge in inches (+/- 1/16").
    2) Measure the overall length of the cartridge in inches (+/- 1/16"), including the end caps (do not include any handles, strings, etc.; a more accurate measurement is made by measuring through the center of the cartridge when possible.
    3) If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16"); match the cartridge end cap configuration.
    4) Make note of the manufacturer (OEM) and model number of the filter the replacement cartridge will be installed in.
    5) Take note whether or not there is a center core (PVC pipe in center).
    6) It is also beneficial to count the number of pleats (+/- 2) in your old filter.
