I have a Culligan AC-30 with 3/8″ and some 1/4″ Guest fittings.
Is the OmniPure K2333KK the right post carbon filter?
How does the RO membrane compare to the one they used in area, filtering ability, etc.
Culligan Reverse Osmosis systems all use the same activated carbon prefilter, activated carbon post filter, and particulate filter. However the reverse osmosis module/membrane varies between the units, and the Post Filters come with different connection settings. In most cases, the membrane is from same manufacturer, with different label.
