Loonen brings spring water to your door in glass bottles

Loonen just entered the bottled water market. The brand sources from protected mountain springs, filters out contaminants, and packages exclusively in glass bottles. Each batch is third-party tested for over 300 impurities, with results accessible via QR codes on the packaging.

Why two beverage insiders started a water company

Clara Sieg, a venture investor and new mom, partnered with David Kimmell — formerly of SpinDrift —) after realizing how little oversight exists in bottled water. Nearly half of U.S. tap water contains PFAS, and over 55% of systems test positive for lead, while bottled options often face even fewer regulations than tap water.

“When I was pregnant with my daughter, I became aware of how much plastic and contamination hides in the water we drink,” says Sieg. Together, the pair learned bottled brands either repackage municipal tap water or source from springs that can still contain trace contaminants like nitrates and arsenic.

The filtration process

Loonen’s water is collected from protected mountain springs in California, transported in stainless steel tanks, and filtered through a chemical-free membrane system that runs it through several steps to clean it up. It’s then remineralized with trace magnesium and Celtic sea salt for balanced taste.
Each batch is verified by accredited third-party labs for over 300 contaminants, including forever chemicals and microplastics — all viewable by scanning the QR code on any bottle or box.

Glass bottles only

To minimize chemical leaching and microplastic exposure, Loonen bottles exclusively in glass. The approach aims to eliminate the risks that come from storing water in plastic bottles, especially those exposed to heat in transit or storage.

Where to buy

Loonen is available nationwide on Amazon and in select California retailers, with nationwide distribution planned for 2026. Learn more at loonen.com.
