TOREAD NSF-50 Certified Watkins 31114 Replacement Tiger River Spa Filter, Compatible Unicel C-8465, PWK65, Filbur FC-3960, 71827, 71828 Hot Tub Filter, 65 sq. ft Hot Spring Spa Filter 1pack

I got this as a replacement for the filter in my Hot Springs Hot Spot spa. So far, I have bought three of these and they are all consistently good quality filters. They work well and seem to be compatible with my spa. They are less expensive than the ones that my local store sells and seem to work just as well.

Perfect fit same as original and alot cheaper. I'll e back for another when needed. Thank you 😊

Excellent filter. Saved $$ over the pool supply place!

Works as it should. I try to extend the life by rinsing every month or so.

These are high quality and they last. We use and re-use them. No complaints.

fit my hot tub

It’s supposed to filter the hot tub So far it seems to do that.

I was so excited to find this filter for my hot tub. It’s a little cheaper than the ones I have previously purchased and so I was a little concerned about that. But so far it has done a fantastic job. I do remove the filter approximately every two weeks and rinse it out with the jet stream function of my water hose. Very economical and perfect for replacing filters in your hot tub!

Great cartridge, good fit. Long lasting
