Rings on both filters mostly broken, cracked and falling off. After 30 minutes of walking I still see muddy water. It was shrink-wrapped, not boxed, so they were probably confused. Bad choice of shipping practices. There was also a 2019 sticker on the shrink wrap so it might have been old. I would stay away from this hot tub brand and find another replacement filter even if I have a hot tub system.
