Does Kirkland Water Have Fluoride In It? (The Truth Is Out!)

Does Kirkland Water Have Fluoride

Kirkland Water, aka Costco Water, is one of the fluoride-free bottled water brands in the US.

Its purified water division has 0 ppm fluoride; spring water has 0.3 ppm, whereas Italian sparkling mineral water has 0.1 ppm.

To give context, FDA limits fluoride content in bottled water to 0.7 ppm, so Kirkland Water clearly satisfies this directive.

But what about other drinking water contaminants and other contaminants? How safe is Kirkland water? Let’s dive deep into this!

💪How Healthy Is Kirkland Water?

How healthy is Kirkland Water

Kirkland bottled water comes from the Cedar River Watershed and the South Fork Tolt River Watershed in the city of Kirkland in Colorado.

These areas, which are strategically close to the well-known Rocky Mountains, provide a source of water that is very clean and free of pollution.

Kirkland water is available in various types, including:

  • Kirkland Signature Purified Water: This type of Kirkland signature water undergoes water purification processes such as reverse osmosis, or filtration process to eliminate impurities and contaminants, providing clean and purified drinking water.
  • Kirkland Signature Spring Water: Kirkland Signature Spring Water is sourced directly from natural springs. It undergoes minimal processing to retain its natural minerals while ensuring it is free from larger particles and impurities.

Niagara Bottling, which owns Kirkland Water, is a member of the International Bottled Water Association (IBWA). 

Now, coming to the part that everyone is waiting for!

🧪Does Kirkland Water Have Chlorine?

The Kirkland purified water is not chlorinated water, and also it doesn’t contain chloramine, as revealed in the 2023 Niagra water quality report. It contains chlorides (salt) like sodium chloride but is way below the 250 mg/L FDA limit.

⚗️Does Kirkland Water Have Pfas?

PFAS (Per- and Polyfluoroalkyl Substances) are a group of artificial chemicals that can disrupt hormones and increase cholesterol levels even if present in levels as low as 2 ppt in water.

Kirkland Purified Water doesn’t have PFAs and other chemicals because it is sourced from springs or regulated tap water.
