Most tap water contains contaminants, and many filters can’t remove newer threats like PFAS (“forever chemicals”). Loonen is UV-filtered to remove a broad range of contaminants, including PFAS, microplastics, pharmaceuticals, heavy metals, as well as chemicals like arsenic, radium and nitrates — all while maintaining the minerality you get from a spring source. Every batch is rigorously tested and verified by third parties.

Loonen is sourced from the Palomar Mountain Spring in California, which meets strict safety, quality, and environmental criteria. We selected Palomar Mountain for its exceptionally low contaminant profile, and natural mineral balance. We work closely with the spring to ensure purity over time.

Loonen is the only bottled water that combines third-party purity verification, PFAS-free test results, glass-only packaging, and complete ingredient transparency. Many other premium brands use plastic caps, do not publicly verify contamination levels, and lose the natural mineral balance of spring water. Loonen offers a US-based, sustainable option with obsessive quality control, great taste, and total openness. If you're looking for the cleanest water available — and want proof, not promises — Loonen stands apart.
