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

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.

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

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.

Produit parti et jamais livré

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.
