My hot tub was given to me and before I got my hands on it, it was left alone and empty except for rain water and trash that sat in the bottom. Cleaning out the lines was extremely hard and time consuming. There was no way that I could clean it all out. This filter was one of the cheaper ones that I found on Amazon, so I figured that I would be replacing it soon. However I was wrong. In a matter of a week my spa was crystal clear and running perfectly. Every week I take it out and clean it and it looks brand new after every cleaning. It has been a month now and I know I should replace it soon, but it still works like it is brand new. I am ordering a few as back ups and I deffinately will replace in a month or so, but right now I am enjoying a beautiful crystal cleat spa and I have to note that I have four teenagers. three of them boys and there is a lot of traffic almost daily from several people.

Arrived broken on the top and possibly used. Caused the chemicals to become difficult to level. Took this one out and replaced it with another new one bought from the spa store locally and it cleared everything up.

Don't bother with the other brands - this filter does the job for half the price. Buy some spares so your tub is always ready to run while you clean (or toss) the old filter.

Replaced existing filter with this one and it works far better. The interior configuration appears to be more efficient. My waterfall no longer becomes clogged.
August 1, 2017
These are just the right size and perform well for my 10 year old Phoenix Spa.
August 17, 2017
The filter was exactly what was described and the packaging was perfect.

IT DOES WELL, LOTS OF FILTER MATERIAL, UNLIKE CHEAP CRAP.

    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.
