I use this in my Hot Tub
The filter fit my Caldera hot tub perfectly.
The filter was priced right and delivered on time. Well done!
Easy to acquire when needed
I had very fast shipment and the product fits perfectly. Nice doing business with.
So nice to have honest online business. Quality product and cheap price, quick shipping, thanks
I had to file about an 1/8 inch off the bottom hole so it would fit
I'm a repeat customer of spadepot. I have only got filters, but it's quick and easy to find the correct one. Products arrive in a timely fashion. Negative, pop up ads in the review page.
This does not fit a Caldera spa unless you cut or grind out the hard plastic lip at the base of the filter. A tedious and messy undertaking. I have purchased a number of this same filter over the years that slid right into place. Manufacturing error that needs to be corrected.
