Choose Your Whole Home Unit

First choose your water source. On the product page, select the 5–10, 10–20, or 20–40 GPM size that matches your maximum water demand.

A Whole Home Unit can cover your entire home. For existing homes, we recommend point-of-use UnderSink units as a second barrier because older plastic or copper plumbing may contribute microplastics, lead solder, or remnants of past water quality.
