    These, INTEX 29001E PureSpa Type S1, look like the same ones that I use in my intex pool. I wonder if they will work in my spa. Thanks for the heads up!

    So many different styles to go with. How is the heck I supposed to know which one is for my hot tub? It is about 10 years old now and I cannot figure out what model number it is.
