Tap water often contains disinfection byproducts (DBPs), which are compounds that form when disinfectants react with organics in water during treatment. These byproducts, including trihalomethanes (THMs) and haloacetic acids (HAAs), are notoriously difficult to filter out once they form, even with advanced home systems.

That’s why we avoid chemical disinfection entirely and start with a pristine spring source, rather than trying to filter out these byproducts after they’ve formed.

Our water is transported in sealed stainless steel tankers, flows through stainless steel lines, and is purified with a non-chemical, physical membrane. It doesn't touch municipal infrastructure or plastic. The result is an ultra-pure baseline, then tastefully remineralized with lab-tested ingredients of the highest quality — clean, balanced, and certified by independent third parties.

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

Loonen is the first purified water that starts with spring water - not municipal sources with disinfection byproducts, and not untreated spring water that can carry contaminants. Our water undergoes a physical membrane, non-chemical purification process that ensures safety and consistency.

Loonen pairs that foundation with third-party certification, glass-only packaging, and ingredient transparency.

The result is a U.S.-based, sustainable option with obsessive quality control and exceptional taste. With proof, not promises, Loonen stands apart.
