Culligan AC-30 Aqua-Cleer 4-Stage RO Compatible Replacement Filters

The Culligan AC-30 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 36 GPD RO membrane filters out impurities larger than .001 microns. The carbon block post filter improves the taste, appearance and odor of your drinking water. You can find and order Culligan-compatible filter replacement kits below.

Helpful Filter Information

Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.

Filter Replacement Schedule

We’ve taken the guesswork out of replacing your filters. Begin a filter replacement cycle by replacing all filters on your system (Filter Kit "YSM"). The following year, or sooner if recommended by the manufacturer, replace all filters except the RO membrane (Filter Kit "YS"). Repeat this cycle by following the helpful diagram below.
