Sta-Rite UDF-10

[patacke]

I am replacing a filter in my under sink two stage filter system. The label on the cartridge I need is Sta-Rite UDF-10. Flow rate 1GPM, service lifer 3500 GAL, 20 Micron Nominal Filtration. It does not have a size on the label. The other filter in the system is a LIquatec CB-975-10 and I have plenty of those. The side of the Liquatec is 2.5 ODx1.25 IDx 9.75L

Here is a filter with the same dimensions and performance as your Sta-Rite filter:
