Proline Millennium 5-Stage RO Compatible Replacement Filters

This high-flow, 5 stage RO system uses a sediment pre-filter and 2 carbon block pre-filters to reduce sediment, chlorine and chlorine by-products before the 75 GPD membrane filters out impurities larger than .001 microns. The granular activated carbon (GAC) post filter treats for taste and odor. NOTE: You can find and order all your filters at once in our 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.
