This product was supposed to be compatible with my hot tub but it didn't fit because it was too high! I only discovered this by putting the new brand next to the old Whirlpool brand. The new one is taller and slimmer than a hot tub. Luckily he's in the garage because there was water everywhere. I had to reassemble the filtration system without a filter and urgently needed to buy a new one. As you can see, one of them is about 1/4 inch shorter than this one.
