The cartridge is a different size than prb 35 **Q: Are these the same as the Watkins 0969601, 90321A filters?** A: Yes they are. I was wondering the same thing, took a chance and ordered one. They are the exact same filter as the 096901, 90321A. **Q: Willthis fit a hot spring hot spot sx current filter is a filber 1807 ?** A: Morning Walter. That is not the correct filter for your tub, I looked up a 2011, 2018 and 2022 and they have the 71825 paper filter. So you would need to purchase that one. We do sell them on Amazon. **Q: How do I need to buy 3 for my jetsetter? Can I use one of these and 2 of the cheaper filters?** A: Depending on the model you most likely can use the ceramic ones or part #71825 which is the cheaper verison the the ceramic filters. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love thes filters *by A***R on April 19, 2026* These ceramic filter work so much better tan regular filters.
