Tap water in the US contains PFAS (detected in 45% of tap water samples per USGS 2023), chlorine, chloramine, lead, and microplastics. Bottled water is not safer — it contains microplastics from the plastic bottle and often fails to meet tap water quality standards. A quality water filter is the most impactful single purchase for reducing chemical exposure.
