How Much Do Whole Home Reverse Osmosis Systems Cost?

Whole home reverse osmosis systems usually range from $12,000 - $18,000 as an installed price. The cost depends on a number of factors but is most closely linked to the amount of water that needs to be generated per day. The amount of pre-filtration equipment required is another factor.  The more water demand, the larger the system required, and the higher the price. Whole home reverse osmosis systems are best suited to rural water situations that have multiple challenges such as high hardness + high salinity (TDS).  They are also well suited to urban residents who simply want the highest quality water available from every tap in their home.

The total cost of ownership of the RO system is also tied to the frequency of membrane and pre-filter replacements. Most whole home RO systems also send significant amounts of water to drain which can drive high water bills. Some systems on the market have minimal or zero waste such as as this system made by Crio Water.
