Spa brand alone is not enough to identify a filter. Manufacturers frequently change filtration systems between models and production years, so always compare your existing cartridge before ordering.

Before You Order

One pair is generally used for a 100 sqft housing and two pairs for a 200 sqft widemouth housing. Compare the overall stacked height and the 40mm centre hole against your existing cartridges before ordering.

Measure the overall length, the outside diameter, the top style and the bottom connection and compare them against this listing. If you are unsure, send us a photo and the measurements of your old cartridge and we will confirm the correct replacement.

Filter Replacement Guide

Spa filters should generally be replaced every 1 to 2 years, depending on usage, water quality, chemical balance and cleaning routine. Rinsing the pleats regularly and soaking the cartridge in a dedicated filter cleaner will extend its working life between replacements.
