About this site

Whole House Water Treatment is an independent, U.S.-focused review and water-quality resource. We cover whole-house carbon filtration, salt-based and salt-free softeners, whole-house and point-of-use reverse osmosis, and well-water treatment.

How we test and rate

Our reviews are built from manufacturer specifications, third-party certifications (NSF, IAPMO) and the real-world maintenance and warranty experience reported by long-term owners. We do not accept paid placement and we do not display prices on this site - pricing on whole-house systems changes frequently and the manufacturer's site is the source of truth.

How we frame water-quality data

Every U.S. utility we cover meets the federal EPA legal limits for drinking water. When we flag a contaminant as "above the health guideline," that refers to the stricter, non-enforceable benchmark published by the Environmental Working Group (EWG), not a legal violation. We pull figures from the EWG Tap Water Database, USGS and EPA, and we never invent or extrapolate numbers.

Why there is no contact page

We are an independent marketing partner of SpringWell, Aquasana, SoftPro and Pelican. We do not stock, ship, install or service their products and we cannot answer product-support questions. For warranty, installation or troubleshooting, contact the manufacturer directly - that's both faster and more accurate.
