Good price

### ⭐⭐⭐⭐⭐ Identical to the Manufacturers
*by P***2 on 11 May 2023*

Today we opened the hot tub after it was closed for the winter. We cleaned the hot tub, emptied out the antifreeze and filled the hot tub. Then it was time to add the filter and the chemical. The filter did such a great job (and the chemicals) that I had PERFECT numbers on the hot tub testing strip. This hot tub filter is the correct size and fit just as promised. Could not be more pleased. Try it, it works!
