Spa Mineral Silver Ion Ag+ Cartridge Filter Sticks for Fresh and Crystal Clear Hot Tubs

I use it for 16 years for hot springs Solana TX. I never fails. I've tried a few times "a yellow" replacement but it's not the same. It's pricey but it's always worth it.

I use these all the time in my Hot Springs Spa Hot tub. I like that they are delivered, great price and same great product that I find in the Hot Springs store

Love the silver stick to keep spa clean.

Works as expected.

Exactly what I ordered

Had to have it . Nice that Amazon Carrie’s this

Have used for years. Very easy to change. I have no reason to try a different brand.

I replace every 4-6 months since my hot tub does not get much use in the winter

These work with my hot spring hot tub, fitting the filter hole. Some other makes don’t. It’s just a matter of shopping round to find lowest price.

Produit parti et jamais livré

Easy fit into our old Hot Springs Grandee hot tub. Very clear water, no problems, even when skipping daily chlorination for a few days eg long weekends away etc. Does exactly what it’s supposed to do.

The product was for the running of a hot tub

These are the standard product I use which is good. However, although advertised as a double pack and working out cheaper I only received one and Amazon refunded the difference. So no real saving on this item
