I tried 3 different filters that ""sort of"" fit my particular spa, but I now realize that only SpaDepot had what I actually needed. I entered the make and model of my spa and they sent exactly the right part for my needs. And it didn't cost any more than the other guys. Well done.
can't tell any difference from the original (& more expensive) filters, Will definitely buy again. Thanks
Easy to order. Fast to deliver.
It goes right in the tuff spa. Cleans easy. Seems to be holding up.
I finally found a filter that fits Thank you. Will be ordering again....👍
I use these in my Strong Hot tub. These filters have the most pleats and do an excellent job of filtering the water and they also clean up quickly and well.
No problems with it.
