This guide describes a product sold under the WFL name. When ordering a current AquaCo system or replacement cartridge, confirm the exact model and compatibility with AquaCo. Historical names do not by themselves establish that two products use the same cartridge or specifications.
The WFL ROUSA Reverse Osmosis Water Filter is a five stage reverse osmosis system with USA made components that connects to your mains under your kitchen bench.- Engineered to provide ultra pure and healthy drinking water.
- Gold Edition Reverse Osmosis Water Filter.
- Includes a sediment and carbon filter (pre-filters) that remove large contaminants and protect the RO membrane from chemicals (disinfectants) like chlorine and chloramines.
- To remineralise the water, at the end the system has an alkaline filter that also raises the pH levels.
- The heart of the ROUSA system is the Reverse Osmosis (RO) membrane that removes more than 1,000 contaminants found in tap water.
- The end result is great-tasting bottled-water quality.

What are the ROUSA Reverse Osmosis applications?
- Connects to the cold water line (Under your kitchen bench).

Recommendations
- If installed under the sink, this filter works with a flow rate of 16 L/h. Therefore, requires a reverse osmosis storage tank to collect water coming form the membrane to then have water available at 3 LPM.
- Because the reverse osmosis membrane rejects polluted water, this system has a black tube that connects to the drain.

What are the filtration Stages in the ROUSA Reverse Osmosis?

1st Stage: POLY SPUN SEDIMENT FILTER
- 9” x 2.5” Layered Polypropylene Sediment Filter with 20, 10, 5 gradient micron pore size for the most efficient reduction of rust, mud, dirt, sand, silt, and other fine particles.
- Protects the Carbon Block from premature blockages.
2nd Stage: OMNIPURE CARBON BLOCK FILTER CARTRIDGE
- 9” x 2.5” Made in USA NSF Certified Coconut Carbon Block Filter with 10 micron pore size for the most efficient membrane protection and funcitionality.
- Eco-friendly filter
- Developed in USA
- Protects the membrane from disinfectants such as chlorine and chloramines.
3rd Stage: ULTRAFINE TFC RO MEMBRANE
- Rejects all molecules greater than 0.0005 microns.
- Only water molecules pass through the membrane.
- Produces acidic water (like rainwater).
- Stores water in a reverse osmosis tank at a flow rate of 16 L/h.
4th Stage: OMNIPURE CARBON BLOCK FILTER CARTRIDGE
- 9” x 2.5” Made in USA NSF Certified Coconut Carbon Block Filter with 10 micron pore size for removal of any taste left behind.
5th Stage: ALKALISER INLINE FILTER
- The Alkaline Filter raises the water pH level, and restores water natural minerals.
