WAVE Hot Tub Filter Cartridges | Replacement Spa Filters For Hot Tubs Purchased In 2020 & Later (Pack Of 16)… (Set of 16)

Wave spas is the only place that carries the right cartridge

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.

Screw on filters what can I say? They filter the water I don’t know what you expect my filter cleaner take them off once a week and clean them the last long.
