Got the filter for a old Softub

Got the filter for a old Softub my old one was over 30 years old but kept it washed every 30 days and looks as clean as the day I got it. The new one is perfect and a great price!. Thank you

Perfect fit

I bought a used softub with a threaded filter and was worried where I would find replacements. And I cross-referenced with a another website and got 2 from The Spa Depot for an amazing price! They will be my go-to for my spa needs.
