6540-501 Spa/Jacuzzi Filter

Direct replacement, works great, my old one seemed fine, but had been in there for quite a while and wanted to make sure that it wasn't harboring unwanted nasties.

After some research, this was the filter in needed for our Sundance Certa tub. Came promptly and fit perfectly in the tub.

Although stated to fit Sundance Altamar, it doesn't. We have an older Altamar that takes another size filter. I would have thought the vendor would know there are two different sizes/fittings.

Works for our spa

Works as expected. Hope will works long time.
