Guardian Filtration ProductsReplacement Pool Spa Filter, For Pleatco PDM25P4, Unicel 4CH-21, Filbur FC-0136

This is the biggest piece of crap i have ever bought not only does it say in desription it was 25 sq.ft. filter its not it is 18 sq.ft.but as soon as i started to thread it in the whole base fell apart im a lic. Plumber by the way so it wasnt me this is thin as paper!! I think it might b another cheaper Chinese brand made to look like a quality brand buyer b ware

I wrote a previous review on this product not being correct. Unfortunately that was not correct. After buying multiple filters and having no luck, I got someone to come out and take a look at my spa. Turns out someone had broken the threads off in the spa to the point that you could not tell by simply looking. This product worked perfectly to replace my Pleatco PDM25P4. P.S. I deleted the bad review.

I used old filter numbers to order and this wa not even close the picture showed item looked right but when I received it it did not even have my old filter cross reference numbers sounds like human error at their company pack wrong.

Fit my dream maker spa hotub perfect and will continue to use these filters like I always have.

I have a Lifesmart LS450DX hot tub and this filter fits nicely. It is slightly smaller than the original filter but the bottom nozzle twist in tightly and the filter works as advertise. Good replacement for a fraction of the cost. I will buy more in the future.

I use this for my hot tub. Fits perfectly.

Does not exactly fit my Spaberry hottub, does not screw into place,but it does fitvin tge chamber, so it works.

Perfect fit.

it did the job ..and fast delivery
