Reverse Osmosis Systems

Proline Plus 5-Stage RO Compatible Replacement Filters

We want to help you keep your Proline Plus 5-stage Reverse Osmosis water filter system in top shape. We sell high-quality compatible filters, cartridges, and parts for your Proline Plus system that are guaranteed to produce the same delicious, pristine drinking water you expect. In addition, these filters can save you a bundle over purchasing proprietary filters. The Proline Plus uses a sediment pre-filter and 2 carbon block pre-filters to reduce sediment, chlorine and chlorine by-products before the RO membrane filters out impurities larger than .001 microns. The granular activated carbon (GAC) post filter treats for taste and odor. Filters should be changed every 6-12 months, depending on water quality and household usage. We've bundled everything you need for your filter replacements, which will save you time and money over purchasing each filter separately.

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.
