Proline EZ Proline-450EZ RO System

Replacement filters for the Proline EZ 450EZ and everything you need to maintain your reverse osmosis system. These aftermarket filters and parts will save you money and produce outstanding filtered drinking water. The Proline EZ 450EZ is a 4-stage RO system that uses a sediment filter and a carbon block filter as pre-filters to reduce sediment, chlorine and chlorine by-products before the RO membrane. The TLC membrane provides 50 gallons of filtered water each day before passing water through an inline GAC (granular activated carbon) post filter that treats for taste and odor to produce clean and great tasting water.
