The ProAqua hot tub filter for Softub PA-625 has a closed top and 1-1/2 inch male MPT threads and is a compatible replacement for the Softub OEM filter 90-802 used in select older Softub 220 models which used the filter with threads instead of the newer style snap-on filter with the collar. It's best to confirm that your Softub model filter is the same size as this filter in order to ensure proper fitment and performance.

How long should ProAqua hot tub filters last?
While most hot tub filters need to be changed every six to twelve months, ProAqua brand filters are made with premium filtration media that delivers more surface area over standard rounded filter fibres and can last up to two years or more, depending on your level of use and cleaning routine.
