Proline Plus Five Stage RO System


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.


Complete Filter Replacement Kit - All the filters you need for annual filter change, including the Reverse Osmosis Membrane. Since the RO membrane only needs to be replaced every other year, on the second year, you can purchase the kit with no membrane.
