Culligan AC-15

Reverse osmosis system

Culligan AC-15 Aqua-Cleer 4-Stage RO Compatible Replacement Filters

This 4 stage RO system uses sediment and carbon block pre-filters to reduce chlorine, chlorine by-products and sediment larger than 5 microns before the 18 GPD RO membrane filters out impurities larger than .001 microns. The carbon block post filter improves the taste, appearance and odor of drinking water. You can find and order all your filters at once, in our Culligan compatible replacement kits below.
