I have a swim spa and the company did not send me any information about what size filter to replace, and so I didn't know anything about how to do it. I came to the site and it actually had my company listed as one of the companies and they were able to select a filter for me. It arrived quickly, and it was the exact right one and it's good quality. I would recommend the products on the seller's site and also the seller because they made it so easy for me!
Just what I thought it would be and it is working great , and best of all it saved be about 18.00
I would buy this product again. Exactly the right product. Excellent filter for a good price. The delivery was fast too.

I have used these hot tub filters for several years, replace every other season. Alternate, wash and reuse. Work great, and a great price!
Always have what I need.
