WAVE Hot Tub Filter Cartridges | Replacement Spa Filters For Hot Tubs Purchased In 2020 & Later (Pack Of 2)… (Set of 2)

Wave spas is the only place that carries the right cartridge

You can find these at a lower cost at various websites.

I bought this to have plenty of filter replacements as we heard the spa needs them to be replaced quite often. The first one is still going well after a few weeks .. have sat in the spa about 5 times so far. Rinsed it and put the same one back in…. So far so good

They're filters, they filter stuff like they should.

Excellent product for replacement in a timely manner.
