Q06 How do I add reverse Osmosis to this system? Or would it be cheaper just to purchase a new system?
Last Updated a year ago

You cannot add reverse osmosis to this system. If you need to reduce overall dissolved solids in the water (reduce TDS) or remove heavy concentrations of harmful metals like lead or copper, a reverse osmosis system like the RTW5 is recommended. But for all-around high-performance water filtration, or where space is at a premium, the CUW4 is the best and the most economical choice for instantly clean, fresh, great-tasting water.
