Works great!
This is the 2nd one of these we have purchased. It fits great and lasts a long time! We clean ours several times before needing to replace. Good product.

Not fully compatible with OEM filter
Price was less, but the trade-offs diminished its value. Thread size for base is slightly smaller and the square footage of the filter paper is only 37.5 sq ft versus 50 sq ft for OEM filter. I had to add teflon pipe thread tape to get a secure fit.

Fits Aqua Terra Grayson
I’m fairly new to the spa thing and when it was time for a new filter, I had a hard time finding the right replacement. I bought this based on another review saying it would fit and doing some measurements. It’s perfect for my little Aqua Terra Grayson spa that I bought at Costco.
