Your 5-Stage Water Purification System

The Proline Plus Reverse Osmosis Process features 5 stages for water purification:

  1. 5-micron polypropylene sediment pre-filter to extract suspended materials such as sediments, rust, insects, and other particles down to 5 microns in size. (Replace every 6-8 months*)
  2. Double carbon block filters to absorb heavy chlorine and chlorine byproducts such as chloramine, THM, and TCE. The double carbon briquettes filter out organic matter from water without release of carbon fines. The carbon block prepares water to enter the reverse osmosis element (Replace every 1 year*)
  3. Stage 2 is repeated.
  4. High rejection  (95-99%) Thin Film Composite (TFC) RO membrane to reject wide spectrum of impurities including Total Dissolved Solids (TDS), bacteria, and viruses down to 0.0001 micron. The product water is stored in the storage tank, while the reject water is automatically flushed down the drain. (Replace every 2-4 years).
  5. In-line GAC Filter is used to remove dissolved gasses, bad taste, and odor from product water. This is the final polishing stage before consumption. (Replace every 1-2 years).

*Depending on GPD consumed and quality of feed water.
