Soft Tub, Sun Rise

The unicel 6CH-25 hot tub filter with a closed top and 1-1/2 inch male MPT threads 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.
