When I first started looking for alkaline water options, Costco quickly came up as a popular choice due to its reputation for quality and value. After trying their alkaline water myself, I wanted to share my experience and some key points to consider before making your purchase.
Why I Chose Costco Alkaline Water
I was drawn to Costco’s alkaline water because of the brand’s focus on purity and balanced pH levels.
