KetofaFC-2402 Spa Filter Cartridge Replacement for Watkins 303279, PFF42TC-P4, 78460, SD-01322, 5CH-37, LSX1057 Free Flow and Lifesmart Hot Tub Filter, 1 1/2" MPT Finer Thread Spa Filter - 2 Packs

Almost as good as factory original at an affordable price. Fits well.

Both the tops and bottoms came unglued. I even tried hot gluing them back on to see if that would work. Nope! I needed pliers to remove the one where the bottom came off while installed in the hot tub. Not worth it. Don't buy!

Thanks for finding my Lifesmart, four person, plug and Play hot tub. They fit much like the original filter and are well made. They're easy to put in and take out, and to clean them I just hose them down well and let them air dry. Two lasted me through the winter last year along with the original. They kept my hot tub running and looking good.Of course these don't replace normal chlorine treatment. I still need to buy the chlorine crystals, and these will not remove any surface gum you might get usually. They make little sponges or balls that will clean that up if you have that problem. That's usually caused by wearing creams, lotions, ect., that get in the water. I just keep one of those floating around in mine so I never have to worry about that.

These filters fit my LifeSmart 7-person hot tub perfectly. They have kept the water crystal clear even in the summer when it becomes harder to keep clean with the excessive heat. They screw in perfectly with no issues and have been able to rinse between cleanings. Overall, very satisfied with this brand and the cost.

not good quality at all. One of them fell apart after being used for a couple of weeks. The blue cap on one end just came off!
