Clarathon 2-Pack Spa Filters Replacement for Unicel 6CH-940, Pleatco PWW50 P3, Filbur FC-0359

WOW, 2 day delivery, good price, and fit the filter housing perfectly. Happy buyer!

Mine was a 2 pack order, I'd like to return this filter that is still in it's plastic shipping encasement as it's not workable for my hot tub. The stock number is Clarathon 0359. I'd like to replace it with the correct size.

Threads are much shorter than my original filters. They do work with my tub, but I would be more pleased if there was just a bit more threads. The closed handle on the top is more difficult to pull out of the filter, but does make cleaning that much more difficult as a whole.

Did what it’s supposed to do And it fit perfectly

The threaded part was longer than the one I replaced. So install gently it was hard to remove due to that. But I just lightly tightened and seems ok. With the new filters there was instructions. This will help in the future. it included how to clean and reuse the filters. This is very helpful.

Here's what I love...that these filters, purchased in a two pack were half the price of the same filter-type...for a single filter! Yeah, we're talking nearly a four-to-one price advantage. Now, finding out what type of filter, you sort of need an NSA analyst to break the code, but once you do it's off to the races. Delivery was faster than advertised.

No dislikes I use them in my hot tub spa

Fit my application just fine. Alot cheaper than buying from a spa store.
