### ⭐⭐⭐⭐⭐ Indispensable
*by C***N on December 11, 2025*

Three things: These cartridges are integral to proper function. These cartridges are expensive. Amazon is the best way to purchase this item.

### ⭐⭐⭐⭐⭐ Great replacement!

Great replacement! Easy to order and install

### ⭐ Freshwater Salt System cartridges are hit or miss
*by F***L on December 23, 2025*

The Freshwater Salt System cartridge has always been a hit or miss for us. A majority of the time they work to produce chlorine for the advertised ~4 months. But a lot of the time they either don't work at all (like this time), or work for far less 4 months. I've checked and rechecked the chemistry and salt level of the tub, so I don't think the issue is the water quality. And the filters are cleaned regularly. So, I'm just not sure how good this product is on a regular, repeatable basis.
