More Water, Less Waste

It’s no secret that the reverse osmosis process uses water to make drinking water. The WaterMaker Five is designed to reduce the amount of water down the drain by 25% over the typical RO system. This represents a significant water savings – over 400 gallons per year for the average family.

Green by Design®​
The WaterMaker Five is smaller, lighter and uses significantly fewer resources in the manufacturing process compared to the typical 5-stage RO. This compact design has an added benefit—the unique flow path utilizes water pressure more efficiently resulting in higher flow from the faucet.
The WaterMaker Five Delivers

The WaterMaker Five features a four-stage prefilter, membrane and postfilter housed in a single cartridge. The fifth stage, an in-line carbon filter, is placed between tank and faucet. Yearly maintenance is quick and easy. No complicated plumbing connections, no tools required.
