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

This cartridge is very similar to the Spas Direct Type B filter but uses a slightly different thread. Measure the spigot thread outside diameter carefully before ordering. Alpine also use a longer CD20 cartridge, so check the overall height too.

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.
