Tier1 Pool & Spa Filter Cartridge 2-pk | Replacement for Spas Freeflow Legend, Pleatco PFF50P4, Filbur FC-2401, Unicel 5CH-45 and More | 45 sq ft Pleated Fabric Filter Media

Looking for a replacement filter is not like ordering a standard part code. They come in multiple sizes and shapes. The description and dimensions given were spot on. I matched up my old filter right to the millimeter....The cost was a 1/3 of what I would of paid in Canada from a Spa dealer.

Came packaged well and shipment arrived in a timely manner. Fit great and easy to use. Will buy again.

they worked out fine

The only filter I use on my spa

Works great! Good price, I will buy again!

I have had a hard time keeping the hot tub maintained properly and these filters work fine along with the right amounts of chemicals . Will buy these again. And for the price, it's easier to change them out more often.

This filter work well for my aqua-terra hot tub that used the Pleatco PFF50P4 open top, threaded type filter

While the filters seem like decent quality, I don't really know. They did not fit my Watkins spa. I did not test them when they arrived, and waited until I needed to replace my filter. It's now too late to return them for a refund.I recommend testing these immediately to ensure proper fit. If they do fit your spa, they seem to be a good value, but I really can't comment on quality.
