Perfect fit.

I was using the original filter for quite some time and finally got a new filter and fit perfectly and works excellent big change and long overdue.

Spa Depot needs to wake up to the 21st Century

Shipping these days is how you get and keep customers. Not charging HALF the Price of a Filter to Replace it with another product From You!

Bad G.
Works well in my Coast spa!

Used this filter to replace a different version. Was concerned as this filter had less surface area (150 vs. 175) than the original filter. 150 works great---really keeps the water clean.
