Filter Cartridges by Measurements
for Hot Tubs and Spas

Here you'll find replacement filter cartridges for spas and hot tubs listed by dimensions. If you know the brand of your filter you may want to look here. If you know the brand of your spa can also look here. In order to find the correct filter cartridge you'll need the following information; the outside diameter of your existing hot tubs filter cartridge +/- 1/32", the length +/- 1/32" and the style (see below) or size (+/- 1/32") of the top and bottom hole. If you find more than one cartridge listed with the same measurements you may need to count the number of pleats. Having the brand name of the spa or filter may be helpful, although the brand name listed may differ from yours.

Ordering is as simple as clicking on the "price button". If there is no price listed, that particular filter cartridge may be a special order. Please call or contact us for special order pricing or if you aren't sure of the correct replacement filter cartridge.

Once you have the necessary information, click the number that matches the diameter of the filter cartridge below (e.g., if your measurement is 7 1/2" click 7). Please note, may pages start with the next smaller size, simply scroll down till you find the correct filter cartridge.
