Proline Plus Five Stage RO System


Everything you need to keep your Proline Plus 5-stage Reverse Osmosis water filter system in top shape. We sell high-quality compatible filters, cartridges, and parts for the 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 12 months, and we've bundled everything you need for the annual filter change, which will save you time and money.
