How does the 3-Stage Under the Sink System work?Updated 4 months ago
We developed our high performance Affinity® filtration technology by combining seven different materials, each of which is known for its strong absorbent properties. Together these materials work harmoniously in a process called ionic absorption. As your tap water passes through the filters, the contaminants will ionically bind to the materials, permanently removing them to give you expertly filtered water.
Each of the three filters in this system is dedicated to removing a different subset of contaminants. That allows the system to handle high quantities of water without excessive water pressure restrictions.
The system is designed for use with cold water only. It should only be installed on the cold water line. This system is not intended to be used with hot water/hot waterline.
You can read more on our technology page and, for the Under-the-Sink System specifically, you can see a more in-depth description of the filtration stages about halfway down in the section titled “How It Works.” And, as always, you can see the exact test results for any of our filters on our Test Results page.
