Artesian Hot Tub Replacement Filters
Artesian Spas (Las Vegas) makes the Island Series and South Seas Series, which sit in the mid-to-upper end of the spa market. Filter sizing has shifted a couple times over the years as Artesian has updated their housings, so don't assume your Island cartridge is the same as your neighbor's South Seas. The label printed on your existing cartridge end cap is the most reliable cross-reference.
The 3 Artesian models below cover the most common configurations.

Quick tip: the fastest way to confirm the right cartridge is to pull yours and read the part number off the end cap. The owner's manual is the backup if the printing has worn off.
