Peak Products Freshwater Salt Replacement Cartridge (Single)

We bought these thinking we would save money. I was wrong, these only last about 6-8 weeks instead of 3-4 months. I would suggest not buying these as they actually cost us more.

Appears to be defective as others have mentioned. Only installed for approx 3 weeks and my salt system went inactive. Water is green, smells of no chlorine. When I took the cartridge out, it appeared as if the bottom may have fallen off and there were recesses on both sides of the cartridge bottom with brown rock-like material which I believe is calcium.

Works great in the salt water hot tub from hot springs spa. Lasts a long time. Easy installation. Same price as in store.

Originally bought this from the whirlpool company I purchased the spa from. Difficult to get back there SoFi checked Amazon & Bingo! It’s here. Quick delivery, easy install.

Great product

The cartridge works good for our hot tub and is a good product the the money we spent on it.

This item was defective. Does not read proper salt level and therefore doesnt work at all.

This is an excellent replacement for our Hot Tub salt water system,
