No brainer if your warranty doesn't require you to buy manufacturer cartridges - Priced right - buy 2 sets of filters to swap when cleaning tub
No need to pay more money - in my opinion - for those overpriced Hot Tub manufacturer labeled cartridges and/or those can you can pick up at their showroom stores. Just be sure your warranty is protected if you go this route. I've got a second hand tub. This is my second set of 3 filters. The first set is in the tub, and I cleaned them when I drained my tub by soaking them in Simple Green for a day and then rinsing thoroughly. Had no bubbles or foam when inserting. To avoid any down time and since these were well worth the costs, I ordered a second set and will just switch out when draining and cleaning the tub to get me back up and running. I'll soak the others, let them dry and have them ready to go for the next time I drain/clean the tub. This one is a no-brainer. And these catch every thing that comes off your body or falls into your tub. The blue tops will fade, but that's due to your chemicals.
